Also it is compatible with most lighting controllers including Growers Choice Master Lighting Controller


PPF & Par Efficacy

The ROI E680 produces a PPF output of 1700 umol/s and a PAR efficacy of 2.5 umol/J making this fixture incredibly efficient compared to other commercial fixures.


Energy Output

The Growers Choice ROI E680 provides its users with an average 40% reduction on energy and HVAC costs. This is the ultimate combination of increasing the amount of light energy reaching your plants while also shrinking costs.


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



The specially deployed 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-E680 with the Growers Choice Master Lighting Controller

This dual-channel controller allows daisy chaining up to 100 fixtures per zone. Enabling complete control of your growing environment with timed on/off switching, sunrise/sunset, and precise temperature readings with dual thermal probes and thermal-threshold auto dim-shutdown for additional protection.
