FHWA Lighting Systems Recommendations for Roadways and Temporary Work Zones

The Federal Highway Administration (FHWA) oversees the wide-scale implementation of lighting systems for streets, road construction, temporary work zones and railroad crossings across the US.

When it comes to work zones, defined as a non-permanent work site that takes place on the road or close to it, the guidelines set forth by the agency provide several tips for improving illumination and safety.

Illuminance Levels

Due to the presence of pedestrians and drivers around public work zones, operators cannot deploy extremely bright fixtures at the site. Furthermore, certain lighting systems, such as light towers, should not be pointed at angles exceeding 65 degrees. Failing to adhere to this recommendation may cause unwanted light spillage, resulting in the creation of glare or blinding (when light beams are directed at passing cars).

For dangerous and detailed tasks, including pothole filling, 216 lux of illumination is recommended by the FHWA. Moderately complex works, such as paving or milling, should be supplemented with a light source that is capable of providing 108 lux. Low-risk tasks, which includes sweeping, surveying and deployment of construction equipment, require at least 54 lux of illumination for temporary work zones.

Conditions for Non-Permanent Road Lighting

According to the FHWA, certain conditions must be met in order to validate the use of temporary lighting systems on roads. When fixed, existing lighting structures are not working or must be removed to make room for the task, regulators recommend deploying temporary fixtures.

Moreover, when safety barriers and pylons are obstructed, lamps should be utilized to illuminate the section of the road. In most cases, one can find temporary lighting systems at non-permanent roadway projects that are supplemented with detours. The fixtures are usually directed at signs and dangerous sections of the work zone. For comprehensive illumination, the FHWA recommends the use of portable light towers which can be found here http://www.larsonelectronics.com/c-189-light-towers.aspx

Overview of Savings for LED Construction Lights Used on RTG Cranes

LED Construction Lights

On construction sites, cranes use numerous lights for safety and illumination. Just how much lighting does a crane require during operation?

A heavy-duty rubber tyred gantry (RTG) crane, which is commonly found in shipyards and ports that hold or stack containers, uses around 14 different lights on a regular basis. These units range from obstruction lights for pedestrian safety to floodlights located on the stacking carrier to illuminate containers during lifting maneuvers.

Operating Costs and Savings

Previously, RTG cranes utilized metal halide lamps for illumination. Although bright, the lights were inefficient and costly for operators. Now construction businesses are transitioning to LEDs, in order to address pitfalls associated with traditional metal halide lamps.

Switching to LEDs can save RTG crane operators up to $5,000 per year (per crane), according to a Milwaukee-based company that specializes in the port crane market. When spread over a fleet of RTG cranes, the savings are enormous. For instance, a fleet of 100 RTG cranes outfitted with LEDs provide $500,000 in savings per year.

Expected Lifespans of LEDs

One of the main reasons LEDs perform exceptionally well on construction sites is due to their extended lifespans. In controlled, ideal environments, LED chips can last up to 100,000+ hours. Most LED lights offer an average lifespan of 50,000+ hours, as the units are rarely installed in locations that are perfectly suitable for the lights. In most cases, the fixtures are exposed to vibrations, water and extreme temperatures. RTG crane operators who use LED lighting systems around 12 hours per day can expect them to last 10+ years.

After its intended lifespan, LEDs will continue to provide illumination. This phase of the luminary’s lifespan typically comes with decreased output. However, unlike metal halide lamps, LED construction lights for cranes may continue to operate more reliably, displaying less issues related to color temperature, flickering and discoloring.

What is Polycarbonate and why is it used for commercial lighting

Traditionally, lighting manufacturers used thick glass to protect the sensitive components of luminaries. Benefiting from its transparent features, the material allows ample amounts of light to pass through for illumination. However, as we all know, glass is breakable. For rugged work environments, like construction sites, operators need something more sturdy and reliable. Because of this, engineers began incorporating polycarbonate into their designs. The amorphous thermoplastic, which can also be transparent or colored (depending on its intended application), is capable of withstanding rough impacts with minimal degradation over long periods of use.

Properties and Characteristics

Compared to ABS, PVC and acrylic, polycarbonate offers higher impact strength ratings. Furthermore, working with the material is considerably easier, with less wastage during formation. Minor bends can be performed without the application of high heat.

Polycarbonate can withstand temperatures up to 155 degrees Celsius. At this threshold, the material turns into liquid. It is important to highlight that the thermoplastic can be heated and cooled several times without sacrificing durability or performance. By comparison, thermoset plastics should only be heated up once, typically when injection molding is performed. A chemical change on a molecular level prevents the reversal of the material. Exposing thermoset plastics to a second wave of high heat will cause it to burn.

Heavy-duty Applications

Based on the benefits and characteristics of polycarbonate, it is possible understand how the material is being used to improve heavy-duty hazardous area lighting systems. Serving as a protective barrier, it prevents harsh impacts, vibrations and foreign contaminants from damaging luminaries. Moreover, the thermoplastic can be molded to create the housing of unit, resulting in sturdy, lightweight benefits.

These days, lighting companies incorporate polycarbonate in compact luminaries to reduce manufacturing costs, unwanted weight and component failure by forgoing the need to install secondary lenses. The thermoplastic is also highly resistant to ignition.

Construction Lights – The benefits

Many people already know about the benefits of using LED lights in their respective homes. And one of the benefits is the economic benefit in terms of using energy effectively and as a better green solution for saving money. Many are also aware that LED lighting solutions can last for a long period. click here for related information.

LED lighting have a number of advantages, especially when it is utilize in working environments. Here are few of the reasons why construction lights could be an excellent solution to many working areas such as offices, construction sites and also in the sports field.

  1. Cost-saving benefits. This is needed to be mentioned as one of the biggest benefits an individual or business people have can have upon buying construction lighting. The LED products aims to achieve for maximum effectiveness in terms of money matters. It will fulfil the needs of every company in making the most out of their budgets.
  2. It boasts an exceptional high-quality performance. This benefit is such a great opportunity to use as a solution for all big companies. While other energy saving lightings solutions may take for a moment to warm it up, the LED lights provide a bright light quickly. This could be very useful in an environment which requires brighter lit spaces for work to be carried out right away safely and more effectively.
  3. Energy-saving alternatives. The CFL will actually decrease the quality of light over time if frequently used. But even if CFL remains so reliable to users as an energy-saving solutions, it is still not efficient as using GU10 spotlight and or shall we say the LED floodlight having PIR to both on which will retain its brightness during the final day on their total life span as what it expects the start of its installation.

Factories, production lines, office spaces, workshops, studious, and the rest of the areas where the workers need to look for the exact detail were all just the specific workplaces which can benefit from this kind of aspects in using LEDs. for further details, click on : http://www.fhtimes.com/news/local_news/construction-to-disrupt-avenue-lighting/article_b7acb5e2-212b-11e7-8ab8-cf9b482f1fec.html
