Now with 40% more light output over the Gen2 model!

The Optic 4 by Optic LED features white-light technology viafour 80-watt CREE CXB2540 chip-on-board arrays. 64 supplemental 5-watt Bridgelux and Epistar diodes surround each COB to further enhance the spectrum and increase intensity.Secondary lenses surround each COB or LED to further increase intensity.

Optic LED's spectrum ranges from 380nm to 780nm, covering the entire PAR spectrum + UV-A and near infrared (far red). The additional green light helps increase photosynthesis deep in the leaves and inside the canopy.Far red light, when combined with red light, has been proven to increase the rate of photosynthesis. 

The Optic 4 offers dual grow channels - channel A turns on the COBs and channel B activates the 5-watt arrays. Turn both buttons on for maximum light intensity during flower.

Forget using an external wall timer because the Optic 4 has a 6-stage timer built right into the side of the unit. Set your timer between 10 to 24 hours with a push of a button.

This fixture is ideal for vegging a 4' x 4' area or flowering a 3' x 3' area.

    VERY Efficient Light but Hot

    This is a great light. It gets really hot though. You'll need a lot of fans if using a tent. Especially during flower. Love the built in timer and the bloom enhancer but the heat output is kind of on the bad side. You probably should buy a really tall tent as much as your space can hold. I'm using a 4" x 2" x 5". Tent closed is 90°+ Tent open/door open is around 84°-88°. This light is better for a room not a tent.
