Soraa Raises the Bar for Precise Color Rendering
Posted by Dave on for ProLampSales
Soraa’s reputation as a premium manufacturer of LED directional lighting rests largely on its VIVID line of LED MR and PAR lamps. On the traditional color rendering scale, VIVID series lamps have a 95 CRI making them suitable for most color critical lighting applications including art galleries, museums, restaurants and high end retail. Other brands also offer LED lamps with CRI in the 90’s. What sets Soraa apart is how they have added other color science...

LED Downlight Retrofits Offer Cost Effective Upgrade
Posted by Dave on for ProLampSales
LED downlight modules provide both an easy upgrade solution for existing incandescent or halogen downlight and an all-in-one package that makes for a seamless looking new downlight. The downlight module includes a non-replaceable LED array or light engine (not a bulb), an LED driver, a diffuser and the trim that sits flush to the ceiling. Advantages of LED Increased rated life is the main advantage of an LED downlight retrofit compared to replacing the existing...
Most Existing Incandescent, Halogen and Fluorescent Photocontrols Will Not Work with LED
Posted by Dave on for ProLampSales
It's not uncommon today for an incandescent, halogen or fluorescent light source to be replaced with an LED light source. Many LEDs are made to be direct replacements for traditional light bulbs and fixtures. In some cases, those traditional light sources have been controlled by photocells that are still in place. When this is the case, it usually results in an LED that does not respond to the photocell. Traditionally, photocontrol manufacturers only had to...

MR16 Luminous Intensity - How Does LED Compare to Halogen?
Posted by Dave on for ProLampSales
We've written here before about one of the toughest problems for manufacturers of LED replacement lamps: achieving light intensity comparable to halogen in the MR16 form factor - particularly for narrow beam distribution. The initial blog post was written in 2014, then updated in late 2016. The update concluded by stating that new breakthroughs in GaN on GaN technology had allowed the manufacturing of single point source LED MR16's – an important step toward replicating...
LED Lighting and Power Quality: The High Cost of Ignoring Power Quality Issues When Switching to LED
Posted by Dave 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...

Lighting Uniformity: Study Shows An Important Advantage of LED Fixtures for Parking Lots
Posted by Dave 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
Posted by Dave 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
Posted by Dave 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...
