PPF & Par Efficacy

The ROI-E680S produces a PPF output of 1770 umol/s and a PAR efficacy of 2.6 umol/J making this fixture incredibly efficient compared to other commercial fixures.

Energy Output

The Growers Choice ROI-E680S provides its users with an average 40% less HVAC costs and up to 40% energy savings! The ROI-E680S not only maximizes light output to help penetrate the canopy and reach those hard to see leaves, but saves you money using less energy in the long run.

The Growers Choice ROI-680S LED grow light allows for even light distribution, and is precisely designed to deliver uniform levels of photosynthesis flux density, or PPFD.


The highly specialized full spectrum fills the negligence of the main photoreceptors and pigments outside the 660nm and 450nm range, and it is suitable for reproduction to aging in indoor environments.

The overall color temperature of FSM's full spectrum is controlled at 3000-3300K, which increases the radiant energy of red light at 660nm wavelength in white light. It provides a beautiful working environment and a more realistic color reproduction degree at a CRI level of 85.

External Control

Pair the ROI-E680S with the Growers Choice Master Lighting Controller

This dual-channel controller allows daisy chaining up to 100 fixtures per zone.
