Want to get a powerful grow light that uses minimal energy? Grower's Choice 680W ROI-E680S LED Grow Light is the right option. It is an improved redesign of 680W ROI-E680 (one of the best LED grow lights on the market). It has a balanced slimmer profile, improved controller potential, and upgraded internal components for enhanced performance.
- Excellent Par Output: It comes with high PAR intensity (2.6 umol/J), which means increased plant growth rates.
- More Controller Capability: This grow light is compatible with Grower's Choice Master Lighting controller and other brand controllers on the market.
- Better Heat and light Distribution: 680W ROI-E680 provides optimal light distribution and better heat management for high-performance.
- Saves Energy: The grow light offers upto 40%. It helps you save tons of money in the long run.
The 680 Watt ROI-E680S is an affordable and high-performance lightning solution for commercial horticulture. It uses 6 bars rather than 8 and includes 3K CMH Full Phase Spectrum for better growing power. This lighting fixture gives you complete control over everything.
It maximizes light output and ensures the light from the bulb reaches those hard-to-reach plant leaves. In addition, this LED light bulb is highly compatible with any lightning controller on the market - Master Lighting Controller by Grower’s Choice and others.
Another advantage is that the light fixture is that it uses minimal energy in the long run. ROI-E680S usually ensures uniform light distribution and photosynthesis flux density or PPFD. The onboard dimming feature allows growers to set the perfect intensity to any growth stage to ensure better photosynthesis. For example, you can set the light intensity to 40%, 60%, 80%, and 100%.
This grow light generates 2.6 umol/JPAR efficacy and PPF output of 1770 umol/s. Thus, it makes ROI-E680S highly efficient, unlike other commercial grow lights. Also, this specialized full spectrum light has an overall color temperature range of 3000 to 3300 K. It builds a great working environment and a more realistic color production degree at a CRI level of 85.
The dual-channel controller allows daisy-chaining of about 100 lights/zone. It provides full control over the grow environment using sunset/sunrise, timed on-off switching, precise temperature readings (with auto dim-shutdown and dual thermal probes.)
Make sure you do not disassemble or open the lighting fixture because it can cause damage to it and avoid warranty. It has safety certifications such as IP65 ETL and DLC. ROI-E680S system also comes with an E680S LED, instruction manual, and 9-inch connecting cable.
