COB Active Cooled LED High Bay Fixtures

The COB LED high bay fixtures are the most powerful LED fixtures for green house and indoor cultivation. They deliver up to 200% of the Par value with 50% of the energy consumption compared to HPS lighting. Their high intensity and effective wavelength increase your production yields with overall energy savings.

The standard COB fixture can be used for all phases of growing, can be customized with specific light recipes. The COB LED high bay fixture is active cooled and supports dimming control.  The level of light intensity can controlled and dimmed by groups or individual unit.  Wireless programmable application control is optional.
