Quantity: 1 x Optic 4
COB Spectrum: 3000K COBS ( Best for Bloom )

The Optic 4 by Optic LED features white-light technology via four 50-watt CREE CXA2530 chip-on-board arrays64 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 lighthelps 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 3.5' x 3.5' area.
