Large, monolithic chip with uniform emitting area of 9mm²
Un-encapsulated die with low profile protective window optimizes optical coupling in endue-limited applications
Lumen maintenance of greater than 70% after 60,000 hours
Variable drive current: less than 1 A through 18 A
Environmentally friendly
RoHS compliant
Applicable for medical lighting, machine vision and microscopy
