The Optic 1 XL Dimmable by Optic LED features white-light technology via a single CREE CXB3590 chip-on-board array running at 100 watts. Featuring a passive heatsink, dimmable Mean Well driver, and 6' power cord, this fixture is a complete light engine. 

The passive cooling system has been overbuilt by 25% to help the light run cooler and extend the lifespan of the COB. 

Modern-day glass lens technology allows the photons to be focused into the desired coverage area (2'x2' for flower) while giving you unprecedented canopy penetration resulting in more developed flowers deeper into your canopy and higher end yields. 

Optic 1 XL is plug and play ready, features a hanging hook on the top side which easily attaches to your ratchet hanger.



The 3500K spectrum is ideal for flowering as it contains alot of red, but is also capable of full-cycle growing.
