LUXEON CoB
High Uniformity and High Efficiency Array
LUXEON
®
CoB is a high-voltage, high-lumen array solution enabling the best efficacy and performance in a very small
Light Emitting Surface. LUXEON CoB is the best choice for high lumen downlights (1000-6000 lm) and directional bulbs
(like PAR/AR111) due to its uniform, robust package.

Notes for Table:
1. Philips Lumileds maintains a tolerance of ±6.5% on luminous flux, ±2 on CRI.
2. Light Emitting Surface (LES) is the inner diameter (phosphor area) inside the dam.
3. Thermal Resistance is based on junction to case with a tolerance of ±0.05 K/W.
