    • Good results
Size: 2×4(320W)
I've been using this light for about 6 months and it's been working great. I have had less than stellar customer service from them - but the product itself is really good.

    • Great Light Great Proce
Size: 2×4(320W)
So far I am really enjoying this light, or better yet my plants are loving this light. Great distribution great price great value. If your in the market for a 2x4 light and your not adding supplemental CO2 this is the best value light on the market.

The performance of this product is very disappointing. I wrote a bad review about this product. I'm rewriting because Mars-Hydro did step up. Communication with the company has been good. I'm receiving a new driver, may take some time to get it ,but they stood behind their product

    • Didn't make it 2 months
Size: 2×4(320W)
As stated, into the second month it started flickering, and the dimmer stopped working. I haven't dealt with customer service yet. I'd actually say 2.5 stars because when it did work, it was a beast of a light. Just a monster. If you manage to get one that lasts I would imagine you'd be very happy with it. 800-900+ par Measured with an apogee meter around 18-20" Edit: I upped the fixture by one star because of how quickly the customer service reached out to me to resolve the issue. So a technical 3.5. It still crapped out in the midst of use, lesson learned. Always have a basic backup. ... show more

    • Great Quality - Does not give off high-risk UV light
Size: 2×4(320W)
UV light can be helpful in certain grow applications, but it is also the largest risk for cancer exposure, so I prefer having the option to add it or not. This is a quality light that promotes the full spectrum but also does not contain extra UV.
