ROI-E680

Great light. Seems to encourage short internodal distance and lateral branching. Seed to harvest.

Still getting used to this light, it's super powerful and I was maybe over cautious this run after cooking my last one!

👍🤠

Had a driver issue right after this grow. Customer support was A+++++ and got a brand new E680s that is now being used in the next grow.

Solid light solid light, a bit pricey at 750 dollars. I'm planning to order future lights directly from Chinese factories for even cheaper costs.

For price they throw down! Customer service is top notch with theses people! I’ve only have had a good experience dealing with issues with my lights!

Super dope light coming hot with a heavy dense bud production(running the roi-e680s)

Love this light

Loved this light, used the dimming function as the plants matured.

Buy one.

This light is very powerful I had to be careful because I would find curling leaves on my plants but just raised the light and dimmed and everything worked out. Great trichome production and size.

Very high quality light. The dimming option is great and the heat dispersion came in clutch too. My AC broke 2 weeks before harvest and at 80% dim the grow room remained under 80F. The yield came out to ~1 gram/watt so if feeding/training properly expect to yield about 1.5 lbs or 680g per light!
