What is UL1598C?

UL1598C is the new UL standard covering LED retrofits intended for existing UL rated fixtures. If the user is retrofitting with a UL1598C classified LED product then the modified fixture retains it's UL rating!  Previously UL ruled considered the modified fixture's UL listing voided.  Light Efficient Design is the industry leader in embracing this new standard across it's HID retrofit product line.

Current 1598C Classified Models:
15 HID retrofit models  replacing up to 400w lamps

2', 3', 4', 5' T8 LED retrofits, 4' 4000K T8 now DLC approved.
