Retrofit Guide

Compare all light types, wattage, and specs in order to accurately upgrade your lighting.

The current solid-state lighting market is very dynamic with many exciting and innovative improvements, however, outdated and low quality technology is abundant at various pricing levels. It is very important to pay attention to the efficacy and lumen output when upgrading to LED lighting, in addition to the LED chip manufacturer. Investing in name brand LED chips will ensure your LED lamp lasts the listed lifespan and you realize the expected energy savings.

Many LEDs focus their light output to a specific beam angle(rather than 360 degrees), often times making it difficult to strictly compare the lumen specs of LED lighting to traditional incandescent and fluorescent lighting which emit light in 360 degrees)
