Posted by on for ProLampSales

Should you buy that cheap UVC LED bulb on Amazon or eBay? It's a 500W equivalent and screws into your table lamp. Great deal, right? Unfortunately, it's starting to come out that these bulbs are fake. Instead of outputting UVC light, many are likely UVA blacklights, and manufacturers are exploiting coronavirus fears to sell fakes to consumers and medical professionals.

LED Direct Replacement: A Guide for 26W, 32W and 42W 4-Pin CFLs

LED Direct Replacement: A Guide for 26W, 32W and 42W 4-Pin CFLs

Posted by on for ProLampSales

Before LED replacements arrived on the scene, CFL pin-based lamps were preferred for commercial downlights. Because of lower energy and demand costs compared to incandescent or halogen, CFL recessed downlights became a common feature in commercial, retail, hospitality and similar spaces. How does LED compare now?

LED Lighting and Power Quality: The High Cost of Ignoring Power Quality Issues When Switching to LED

LED Lighting and Power Quality: The High Cost of Ignoring Power Quality Issues When Switching to LED

Posted by on for ProLampSales

The effects of power quality on LED lighting performance generally receive little attention prior to installation for most commercial building applications. Power quality issues such as dips, harmonics, interruptions, transients and surges can result in expensive, early replacement of damaged or failed LED lighting equipment. While facility managers involved with smaller commercial projects may be able to ignore power quality without much consequence, larger industrial LED lighting projects, such as the replacement of existing HID...

LED Troffers Offer Strong Case To Replace Fluorescent

LED Troffers Offer Strong Case To Replace Fluorescent

Posted by on for ProLampSales

When comparing LED troffers and retrofits to fluorescent troffers, the most LED fixtures will either exceed or match the specifications of the fluorescent fixtures. LED lumen output often matches that of various fluorescent configurations but it, along with control compatibility, requires careful consideration to ensure the LED installation will meet the needs specific to the application.

Lighting Uniformity: Study Shows An Important Advantage of LED Fixtures for Parking Lots

Posted by on for ProLampSales

One of the fastest growing segments of the LED commercial lighting market is site, area, street and parking lot lighting. Owners of commercial property and municipalities in particular are looking at LED solutions for new developments or to replace HID fixtures in existing applications. In this post we will look at occupant perceptions of safety, security and visibility in parking lots. Specifically, we will review a study that uses LED parking lot light fixtures to...

Evaluating an LED Retrofit of HID High Bay Fixtures in a Maintenance Facility

Evaluating an LED Retrofit of HID High Bay Fixtures in a Maintenance Facility

Posted by on for ProLampSales

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has conducted a field research project evaluating installation issues and performance of a high bay retrofit where the existing metal halide bulbs have been changed to LED. High bay fixtures that use metal halide lamps in warehouses, shops, sports facilities and big box retail offer an opportunity for significant energy savings with LED HID replacement lamps. The high wattages for metal halide range from 175 watts...

How to Make Sure Photocontrols Are Compatible With LED Lighting

How to Make Sure Photocontrols Are Compatible With LED Lighting

Posted by on for ProLampSales

Photocontrol devices use photocells to determine ON/OFF status of outdoor lighting based on the ambient light level. While generally understood as responding to visible light, some photosensors also respond to infrared (IR) and ultraviolet (UV) radiation. Normally used for roadway, area, parking, flood and security lighting, photocontrols automatically control the ON/OFF cycle to optimize the effectiveness of the lighting and maximize energy savings. In daylight harvesting applications, the photocontrol is mounted inside the occupied space...

Guide to Beam Metrics for Comparing LED to Halogen Directional Bulbs

Guide to Beam Metrics for Comparing LED to Halogen Directional Bulbs

Posted by on for ProLampSales

LED light is inherently directional. Most traditional light sources - incandescent, halogen, compact fluorescent and HID - emit light in all directions. For these light sources to have specific directional characteristics, the lamp is made with a reflector and sometimes a lens to modify the illumination so it becomes more focused, or directional. For example, PAR halogen lamps are available in a range of beam angles from 60°, a wide flood, to 8° a narrow...

What Happened to the 100,000 Hour LED Bulb?

What Happened to the 100,000 Hour LED Bulb?

Posted by on for ProLampSales

Years ago, LED bulbs were often advertised as having 100,000 hours of rated life. However, that has largely disappeared in favor of the 25,000 hour bulb. Some manufacturers even make 11,000 hour LEDs. Learn what's changed in how we measure the rated life of LED bulbs, because of the unique nature of solid state lighting technology.
