Towards the indestructible LED
on
The fantastic chemical resistance is partially attributed to its gold-plated lead-frame and it has been tested to IEC68-2-43 (15 ppm): DLOP < 10%, Du’v’ < 0.006 after 21 days.
Lumileds' Matthew Everett claims that engineering for chemical resistance is all about selecting the best materials and then testing those materials under harsh conditions. The results: an LED that lights 100 Khours at 105 degrees C. Its 4,000-K and 70-CRI output is 125 lm at 134 lm/W driven at 150mA. At 70 CRI, options are 4,000, 5,000 and 5,700 K. At 80 CRI, options are 2,700, 3,000, 4,000 and 5,700K.
So shine a light om me, HR30!
