Philips GreenPower LED Production Module is available in an UL-approved 110-volt version in the U. S. The modules are available in deep red/blue (general light good for a variety of growing applications) and deep red/white (if work light is needed). At between 35-43 watts, the modules can replace many T5 or T8 grow light applications and reduce energy consumption. The Production Modules are being tested on ornamentals for day length extension and photoperiodic manipulation.
