Sunlight Direct brings us a very effective and useful hybrid solar lighting technology. It consist of a device on the roof that collects and concentrates sunlight throughout the day. After filtering the UV and Infra Red spectrum (for heat reasons), this light is piped down to the building interior where it can be distributed via hybrid fixtures. On sunny days the fixtures might emit 80% natural sunlight mixed with 20% fluorescent or incandescent. On cloudy days it might be just the opposite. The natural light has been shown to improve our productivity, help synchronize our circadian rhythms or sleep patterns. Microprocessors control the system, aiming the collector directly at the sun (within accuracy of .1 degrees) throughout the day and adjusting the blend of natural light and artificial light at the fixtures to keep a steady light level.

Lightpipe lighting from Sunlight Direct has the ability to make a significant difference in your energy cost. With some proven health benefits as well. We’ll certainly be keeping an eye on this and future developments like it.
