Understanding NEC Guidelines for Lampholders and Lighting Guards

Lighting components used in extreme work sites need to be protected with lighting guards, to prevent damage to the luminary. The National Electric Code (NEC) has acknowledged this requirement in their handbook, specifically in Section 410.

Read on to learn about NEC recommendations for equipping industrial lights with protective components.

Damp and Wet Locations

The 2011 edition of the NEC handbook suggests that lampholders be applied, based on the environment of the work site (Section 410.96). This is an update from a previous version of the code, which recommended lampholders used inside damp or wet locations to be weatherproof. The update was needed because weatherproof is not a common feature in lights for damp locations (based on its definition).

The NEC defines damp locations as environments with moderate protection from harsh weather and the ingress of liquids. Examples of such locations include porches and canopies where only special types of spotlights should be used.

From a cost perspective, the updated NEC guideline could help businesses reduce operational and equipment costs in damp locations (while streamlining compliance with the NEC handbook), as weatherproof protection requires robust materials and ratings.

Combustible Materials

Lights setup next to combustible materials must also be well protected, via shades or guards, as set forth in NEC Section 410.11. Notice that this guideline does not include lampholders.

An update to the 2011 handbook includes lampholders, but with special temperature-related conditions. According to NEC Section 410.97, such components should be reinforced with guards, when next to a combustible material, ensuring exposure does not exceed 194°F.

But why this threshold?

By design, lampholders are subject to increased heat and high temperatures due to their applications. The units are primarily used to hold lights that emit large amounts of heat. With this in mind, there is a risk of accidental ignition. Most lampholders typically fail due to overheating, rough contact or mechanical oversight.…


Green LED Strobe Light Applications in Industrial Work Sites

LED strobe light can come in different colors and flashing patterns, depending on their applications.

For instance, red strobing units are typically associated with emergency vehicle fleets, including fire fighters and police. Blue LED strobe lamps are suitable for law enforcement, while white or clear is a secondary color to boost visibility during operation.

This article focuses on widespread applications for green LED strobe lights.

Applications and Specifications

Green LED strobe fixtures are not associated with any official activities. However, the light color can be applied to improve safety or security, as it is a preferred choice by emergency representatives.

The Department of Homeland Security recommends these compact lamps for use on private vehicles, which must be owned by a certified personnel in the medical field. Such professions include medical service driver, first responders and more.

According to the agency, the units should be capable of emitting more than 50 candlepower and must be installed at the roof of the vehicle. Furthermore, the LED lights must strobe at 360 degrees in a flashing pattern for maximum visibility. Only two lamps can be displayed at a time.

The type of LED strobe light recommended by the Department of Homeland Security is a unit that utilizes a green lens for color. Green bulbs with clear or uncolored lenses are not preferred by the agency. The robust units should also be standalone (not incorporated with other LED lighting systems on the emergency vehicle).

Acquiring a Strobing Permit

In some locations in the US, a permit from the relevant agency is required, when operating a green LED strobe light. Requirements for the permit are minimal and may vary from state to state. In Indianapolis, the application for green light permit requires the individual to first obtain a state certificate number and a valid driver’s license.…


FAA Regulations for Obstruction Lighting on Industrial Wind Turbines

Tall industrial structures, from cranes to temporary towers, are closely regulated by the FAA. The agency asserts guidelines for visual safety, ensuring that proper lighting is available for detection. Aircraft pilots rely on obstruction lighting to evade the structures at night.

For wind turbines, the FAA provides several recommendations in relation to the type of lights, flashing efficiency rates and spacing during installation.

FAA Regulations and Wind Turbines

The application of obstruction lighting in wind farms is governed in FAA Advisory Circular AC 70/7460-1K (Chapter 13).  When a group of wind turbines is used to form a ‘farm’ the agency asserts that only three turbines exceeding 200 feet (from ground level) can be utilized.

Interestingly, not all of the units require obstruction lighting.

According to the FAA, operators must carefully install the lights, so that spacing does not exceed ½ statute mile. By definition, a statute mile is equivalent to 5,280 feet or 1,609.34 meters.

Flashing and Durability

The FAA cited Type L-864 red flashing luminaries as the standard for illumination at night. In most cases, these are strobe lights (with flashing capabilities), which are used for visual notification. When multiple flashing lights are applied in a wind turbine farm, the luminaries must have simultaneous flashing patterns.

As for materials used, the FAA recommends the use of aluminum (under IFH-1710). At high altitudes, the units are exposed to devastating winds, rough weather and debris. Because of this, ease of maintenance is prioritized by the FAA.

Field-repairable features are required to streamline access and reduce complex maintenance tasks. For obstruction lights on wind turbines, this includes an accessible hinged door that can be locked and secured for protection. To reduce frequency of maintenance, LED lights can be utilized. The luminaries offer 50,000+ hours of illumination and support compatibility with low voltage (DC) sources and photocell sensors.…


3 Advantages Of Led Temporary Lighting For Applications

Nowadays, technology is changing almost faster than you can blink and the world of lamps is not any different. LED Temporary Construction Lights is the new frenzy, but what exactly are the huge benefits and just how do they apply to users of temporary job site lamps?

Higher Durability

Typically LED lamps are replacing some lighting with a glass envelope and possibly a fragile filament, such as fluorescent, incandescent, or high strength discharge (HID). Through the elimination of these vulnerable components, LED Temporary Construction Lights offers users a more solid solution for industrial work lights. This is key for users of short-term jobsite lamps, where lighting is subjected to a whole lot of misuse from disassembly, travel, and reassembly.

Longer Life

LEDTemporary Construction Lights has the benefit of offering a long life period, typically 25,000 hours or more.  Compared to incandescent, which even durable models are often rated at 10,000 hours or less, LEDs can offer users the best profits in return even before their lower ability consumption is considered!

Lower Electricity Consumption

Lower power intake means lower voltages, lower currents, or both. This offers to the end user:

  • LOWER CURRENT DRAW

LED Temporary Construction Lights use less electricity, and less vitality means lower current. For users of temporary job site lighting, this is key. Often short-term work lights are being used in the format of long strings, such as what is employed during tunnel construction. Over these long strings, voltage damage due to the resistance to the cable can be considerable. To pay heavy gauge lower resistance cable television is used. This lower current draw allows a lighter measure cable to be used, which to the end user means lower cost. Alternatively, LED light allows a lot longer strings have been recently available.

  • LOWER VOLTAGE

Less power also means that you can run the LEDs at alower voltage (if you are by using a light made for this type of software), meaning that high lumen outputs are now open to users who have low voltage requirements.  Incandescent offerings have been designed for low voltage users for a long period, but their high power consumption offers a significant disadvantage at these low voltages.

High electricity at low voltages means high current, and high current means high voltage drops over long cable lengths. In earlier this, low voltage users got to pay by using fewer light bulbs or shorter strings than their higher voltage counterparts. No more! Now low voltage users can decide on a temporary lamp solution in an LED. These LED Temporary Construction Lights provide light outputs and string measures that are competitive with their high voltage incandescent equivalents.

  • LOWER COST

Lower wattage means fewer kilowatt time on your expenses. A 100-watt incandescent uses that, 100 watts. A typical 100 watt LED comparable uses 15 w.

For a 1000 foot string with bulbs every ten feet and an electricity cost of $0.07 per kilowatt hour, the LED will save the end user $0.70 each hour. In the 25,000-hourlifespan of the bulb that means a personal savings of $17,500!

There are various advantages to using LED Temporary Construction Lights as your short-term job site lighting provider. Keeping up with the trends can allow your job site to get the job done well and do it securely.…


Improving Lighting Enclosures Designs for the IoT Era

The Internet-of-Things (IoT) sector is heating up with advancements in connected technology reaching a myriad of industrial products, such as lights, sensors and lighting enclosures. The cutting-edge trend is here to stay, forcing manufacturers to rethink traditional enclosure designs for their products.

How will new enclosure designs cater to IoT-powered lighting systems? Find out below!

Boosting Exposure and Security

A set of smart lamps connected via a secure network is typically equipped with sensors that gather data about the surrounding environment in real-time. To improve effectiveness, the fixtures (along with their sensors) must be installed within the target location. This allows the sensors to operate optimally, with minimal obstructions.

Such installation requirements would make the lamps more susceptible to tampering. To discourage unwanted interference, the enclosure of the fixture should include physical locks.

Alternatively, it would also be possible to install an additional sensor in the enclosure that notifies the controller or supervisor, in the event the unit was opened or compromised.

For rugged, extreme work sites, it is common practice to utilize a NEMA-rated enclosure that is designed to prevent the ingress of destructive compounds for lights. This requirement will likely become more widespread and important for IoT-powered luminaries, especially in hazardous locations.

Modularity and Scalable Lighting Solutions

Industrial facilities are large consumers of heavy-duty lamps and custom-built solutions for demanding projects. The ability to expand lighting capacity – quickly and efficiently – is a huge advantage for fast-moving businesses. Improving the modularity of lighting enclosures for fixtures is a great way to promote expansion. For instance, a modular enclosure may include increased power management features to cater to custom, dense lighting configurations.

Additionally, the units should be modifiable to serve custom cable connections and space-saving requirements. For seamless access to the enclosure during inspections or maintenance, it is also recommended for the doors or openings to be reversible.…


Non-sparking vs Anti-static Equipment For Industrial Work Sites

For hazardous locations, mitigating sparks and static is a critical part of reducing unwanted ignitions of flammable compounds. To address such issues, industrial equipment manufacturers utilize non-sparking materials, such as plastic, aluminum and wood. While anti-static equipment mostly relies on specific practices to reduce the buildup of charged elements.

What’s the difference between non-sparking and anti-static tools? Find out below!

Non-sparking Materials

Non-sparking materials are commonly applied to explosion proof equipment, such as lights, power distribution stations, fans and etc. Furthermore, facilities that handle flammable substances on a regular basis, such as oil and gas, refineries and chemical processing plants, are known to rely on non-sparking tools for safety.

This type of material may also be used to decrease hazards related to combustible dust, mostly found in Class II, Division 1 & 2 work sites. Powdered milk, flour and cornstarch are examples of volatile dust.

The term “non-sparking” simply refers to materials that do not contain ferrous metals, such as steel and iron. Generally speaking, manufacturers may select non-sparking materials for their products based on strength (in addition to the ability to reduce sparks), as the range between extremely durable, non-sparking materials, such as copper-aluminum alloys, and weak options, such as leather, is very wide.

Anti-static Surfaces and Practices

Anti-static materials are effective against electrostatic-related elements around sensitive electronics. However, in classified work sites, static can ignite flammable compounds in the atmosphere.

In some cases, reducing the risk of static is achieved through the observation of safety guidelines in the workplace. For example, to avoid the creation of static, workers and affected materials should be grounded.

A facility may also use tools made out of specially-engineered plastics to address static build up. Such materials must have low surface resistivity rates, in order to decrease hazardous interactions with nearby surfaces. Additionally, temperature and humidity levels should be managed to support anti-static equipment.

Light for Commercial Work Sites- Natural vs Artificial

Light for Commercial Work Sites

Light is vital to sustaining business operations and employee productivity rates in commercial sites. However, not all light sources are equal. At a very basic level, illumination can be implemented over the work area using natural sunlight or artificial lighting systems. OSHA has also set standard for work site lighting.

Improving Moods and Energy Consumption

Natural lighting comes from the sun. This form of illumination can be maximized by installing large windows and sky-lighting systems at the ceiling. For daytime operations, natural sunlight is directly connected to an increase in productivity, mood and motivation. It also contributes to vitamin D, for individuals who are lacking the vitamin.

Drawbacks related to natural lighting includes the generation of heat. Sitting next to a big window with the sun beaming directly at the computer or one’s face can be frustrating, due to heat generated by the beams. Additionally, natural light could also cause unsightly glare and may be difficult to control without the right equipment. It is only possible to direct sunlight to general locations of the facility. For task lighting, it is almost impossible to efficiently “funnel” sunlight beams to a dark part of the office. Furthermore, natural sunlight isn’t always available, as cloudy and nighttime conditions could affect the amount of natural light entering the building.

Task Lighting and Accurate Illumination

Artificial light sources include lamps, permanent lighting systems, handheld lights and more. They are incredibly useful for illumination in rooms without access to natural sunlight, such as laboratories, classified facilities, underground storage centers and projector rooms. In some cases, even with natural sunlight available, artificial lighting is preferred because it can easily be controlled to suit the needs of the facility.

Artificial lighting is also very reliable. As long as power is available and the lighting system is operational, illumination can remain constant. From a cost perspective, natural sunlight is free and artificial lighting comes at a price. This doesn’t usually affect the adoption of artificial lights, as such equipment is considered to be essential to maintaining commercial operations.…


How Safety Light Curtains Work?

 Safety light curtains are a modern way of protecting personnel around many risky machines. Safety light curtains offer freedom just like temporary Construction Lights, flexibility and reduced operator tiredness when compared with traditional guarding methods, for example, mechanical barriers, sliding gates and pull-back restraints.

By reducing the need, where applicable, for solid guards, safety lights curtains merely simplify routine tasks like machine setup, maintenance and repairwork the same as construction light.

How The Safety Light Curtain Work?

A photoelectric transmitter projects an array of synchronised, parallel infrared light beams to a receiver unit. When an opaque object blockbeams in the sensing field, the control logic of the light curtain then sends a stop signal to the protected machine.

The transmitter unit has light emitting diodes (LEDs) that produce pulses of invisible infrared light when energised by the light curtain’s timing and logic circuitry. The light pulses are both sequenced – one LED is energised after another – and modulated – pulsed at a particularrate. The corresponding phototransistors and assisting circuitry in the receiving unit are made in such a way that they detect only the particular pulse and frequency made for it. These methodsprovide enhanced safety and rejection of external light sources. The control logic, user controls and diagnostic signals may be contained in a different enclosure or be closed together in the same housing as the receiver electronics.

The use of construction light Safety light curtains is Control Reliable. Control Reliability is the machine capability to control components and related interfacing to attain a safe state in the event where a failure occurs within their safety-related functions.

In contrast to photoelectric sensors, light safety curtains use self-checking circuitry to monitor the light curtains for internal faults. If an internal error is identified, the light safety curtain in an instantcommunicates a stop signal to the guarded machine. The light curtain then places itself in a lockout condition. Only after replacement of the failed component and an appropriate reset will the light curtain be restored to operating condition. Another example of safety monitoring are the safety redundant safety outputs as done using construction light.

Typical Applications
Protecting an operator from the risk associated with material positioning or where a process is performed is known as the point of operation guarding. Construction light is Another name for the point of operations is the zone of hazardous operation or the pinch point. This design of safeguarding is associated with mechanical and hydraulic power presses,  forming,  moulding presses, stamping, riveting, automated assembly machinery and eyelet. Light curtains used in these applications are chosen for finger and hand safety.

Perimeter guards safeguard the edge or boundary defined by a robot machine or other equipment. In these applications, light curtains are usually selected to detect the presence of personnel and signal the device controller to hinder hazardous conditions while staff are present within the safeguarded area. The light curtain reset switch also must be located outside and around the view of the protected area to avoid an inadvertent resumption of machine movement. Light curtains for perimeter guarding applications are chosen for torso detection although you can still use construction light.

The Importance of Choosing the Right Work Lights for Harsh Conditions

Illuminating work areas at night can increase safety and productivity. It’s important to choose work lights that light up the area effectively to improve visibility and increase safety aspects. This is especially true in harsh conditions, such as the Australian outback, or in touch industries, such as mining, drilling, earth moving or agricultural industries. See other details and make sure you have it all.

Here are some things to look for before choosing work lights for harsh conditions:

Durability and Toughness

Always seek out heavy-duty lighting built specifically to withstand the environment they’ll be used in. This means ensuring that all lamps are encased in high impact nylon housing that reduces the risk of breakage. Lights should also be made with hardened glass lenses.

There are plenty of heavy-duty flood lights and spot lights available that are specifically designed and made to withstand extreme conditions that exist in the mining, drilling, earth moving, or agricultural industries.

Longevity

Illuminating work areas properly at night is important for safety and for productivity. For this reason, you need to be sure you choose lighting that will last a long time without needing to be replaced. This reduces maintenance time and ensures work areas remain well-lit when you need them most.

Halogen bulbs do offer long life spans, but there are also many benefits to considering LED lights as well. For instance, LED lights don’t simply go out when their life span ends. Rather, they tend to dim gradually over a period of time. This still allows the area to remain well-lit until the lamp can be replaced, thus improving safety on the work site at night.Get some information from http://www.mustangandfords.com/parts/1704-mychanic-expands-led-work-lighting-with-two-new-offerings/

Weather Resistant

The harsh weather conditions in the Outback mean that any lights or lamps chosen need to be able to withstand the elements. Ideally, you should always choose work lights that are encased in dust resistant and water-resistant casing.
The power switch should also be housed in waterproof silicon rubber casing to prevent electrical shorting and other hazards.

LED vs. Halogen Lighting

Work LightsHalogen burns very hot, producing plenty of yellowish light and plenty of heat. Work lights using halogen bulbs are good for casting a wide area of light around a work space. This makes them ideal for use as flood lights or for spot beams to illuminate specific areas properly. Take care that safety precautions are taken, as the bulbs can become extremely hot after use.

LED lights cast a very bright, white light, which can be ideal for lighting work areas for maximum visibility at night. These lights use much less power than other forms of lighting, so they’re very efficient. They also don’t generate heat, which increases safety and reduces risk of fire accidents. No more extra tricks, choose what you want, and choose only the best.

Working in extreme or harsh conditions is difficult enough. Don’t make it any more difficult than it needs to be when working at night. Choose the right work lamps to keep important areas well-lit and you’ll reduce safety risks dramatically.…


How To Choose The Appropriate Work Light for Your Needs

Whether you work inside or out, lighting is always an important element that must be considered. When you work outside during the evening, you are likely to need a high intensity work light to help you complete your tasks. However, not all work lights are the same nor do they offer the same features. Choosing work lighting is not easy but looking into the Internet is the best solutions to have. With so many different options on the market, how do you go about picking the best light for your needs? When choosing a work light, there are three considerations that you will want to keep in mind.

Purpose

When picking out a light, you need to know exactly what you are using the light for. For example, working outdoors at night on construction projects will require more intense lighting than working in an office or garage. Photography also requires more specific types of lighting. Once you have established the purpose for which the light is needed, you can begin to compare the lights that are designed for your particular needs and thus, narrow down your list. This is such a very important thing to keep in mind and one of the most important features to consider on work place.

Power Source

You may not always have access to a power source and this is something that you need to keep in mind. Many lights are designed to run on battery power for extended periods of time, but come with other considerations such as the cost and availability of batteries. If you have access to a power source, such as a vehicle or a power outlet, your options will be considerably larger. Also keep in mind that some lighting sources do not adapt to the normal power outlets that are available. Be sure to research the appropriate power source that you will need before purchasing any type of lighting element. Power saving is also important to see before choosing a lighting source to save money.Read post from http://www.stuff.co.nz/manawatu-standard/news/92600978/led-street-lights-are-fine-but-there-are-not-enough-of-them for more details.

Brightness

Led lightsDepending upon the scope of work you do, the brightness of your required work light may vary. Some variations of work lights come with fluorescent lighting while others rely on LED lighting. If you are working in a dark atmosphere, fluorescent lighting may be what you need. Other purposes may be carried out with simple LED or regular wattage bulbs, especially if you are working indoors. Lots of people choose LED lights not just because they can save money, but also they can use it well in their work as it really delivers a high-quality, clear lights at night.Checkout website at http://www.larsonelectronics.com/c-603-temporary-construction-lights.aspx
