Good quality of light is a basic requisite in any commercial or domestic buildings. The Solid State Lighting due to its inherited property of color tuning has crossed the threshold of the market replacing conventional light source. A systematic understanding of performance of LEDs at different Correlated Color Temperatures (CCTs) is required to design tunable LED module. Optics in LEDs dictates the quality of light output from the luminaire. This paper brings out the outcome of the experiment conducted on multichip RGB LED at different CCTs. Color quality of the LED module is assessed using CIE TC1-90 recommended metrics.CollimatorPL119940 is identifi ed as suitable secondary optics for LED luminaire that produces optimized spectral profi les with high color rendering index.
