Aircraft lighting is the cornerstone of Day-Ray’s products and
we produce some of the most reliable lighting products in the industry.
Our focus is on developing more efficient, reliable, lightweight products
that create less heat and require less maintenance. We have designed
and built some of the best interior aircraft lighting systems in the industry
and pioneered many of the technologies in use today, including our
patented fluorescent dimming, and our arc detection and suppression
systems. We are also on the leading edge of new LED lighting
technology.

Day-Ray provides sophisticated electronic circuitry across a vast range
of ballasts, transformers and dimmers to meet the lighting requirements of
any aircraft. We have more than 100 PMA designs to meet your lighting needs.
Our revolutionary K100-140-001 incorporates the most advanced arcing protection
