The ROI-E680 is a high-performance LED grow light, ideal for small and large indoor growth systems. It's 1700 Umol/sec output provides just the right environment for sufficient indoor growth.

With up to 40% better efficiency, the E680 can cut down your bills while providing a full spectrum of light at a 120-degree distribution angle. It features better controllability at ranges beyond 660nm, giving more realistic growing conditions for photosynthesis.

The light is suitable for mounting at any height beyond six inches. It offers passive thermal management with up to 10 Volts dimming. It comes with a nine-inch connecting cable and a complete compatibility range to operate with most LED controllers.

At full potential, it can offer a life cycle of more than 54,000 hours, so you grow more and spend less.

The ROI-E680 features a 42.4” x 42” size. So, it’s most suited for 4’ x 4’ or 5’ x 5’ grow tents. It’s a powerful light for such a compact design. With IP65 certification, there is guaranteed water and dust proofing, so it's a perfect option for rugged use.


Balanced spectrum, Incorporating Grower’s Choice famous 3K CMH Full Phase Spectrum for superior growing power with best possible LED diodes available.

High Performance:

  • 1700 μmol/s Total Output
  • 2.5 μmol/J System Efficacy

Energy Saving and Easy HVAC:

  • Up to 40% energy saving
  • 40% less HVAC requirement

Full Spectrum

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.

Total Control

With onboard dimming function, growers can set the ideal intensity at any stage of plant growth for optimal photosynthesis activation. Also, it is compatible with most lighting controllers including Grower’s Choice Master Lighting controller.

Even Light Distribution

Precisely designed to deliver uniform levels of photosynthetic photon flux density (PPFD)

Quality Components

Industrial grade manufactured with Osram Top Bin Diodes and ultra-efficient driver
