Global Lighting Technologies (Brecksville, OH) has improved the performance of its standard 2×2 ft.-square, edgelit, LED-based flat panel downlight assembly by developing a brighter and more efficient SSL for ceiling lights that delivers efficiencies greater than 70 lumens per watt using standard GLT 2×2-ft troffer packaging with a CRI of >80. The LEDs used in the new panel have increased in brightness from approximately 100 lumens up to 130 lumens. Using the same number of LEDs (100) as in the previous iteration, GLT offers an increase in brightness of up to 3,250 lumens at a color temperature of 4,000 K.
