Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Lite and Brite!!!


This was first time using, I was so very surprised about the service I recieved and the speedy process in getting me my order as it was on short time frame to complete my commerical project. I also would like to say that the packaging was great and not one broken lamp in shipment and when we powered project up we did not have a single lamp that failed!!!!!! This is almost un-heard of. I would like to thank all that was involved in ordering my materials, packing and shipment and I might add, I had all my lamps on dock at shop in three days and it was late afternoon when I ordered. I will definetly tell others about the service, quality of product and speed at which your company acts. AGAIN THANKS!!! Jasper Brooks J. Brooks Electrical Serv. & Contr.
