MARS HYDRO FC6500 730W Samsung LM301H EVO LED Grow Light 5x5, 1530Pcs Diodes with Smart Control Function, 730W Full Spectrum Foldable Dimmable Daisy Chain Grow Lights Bar for Indoor Growing

Great little light, exactly right for my tiny growing space. Plants love it.Does not raise the temps in my space at all. If I had worse ventilation that would likely be another story, but you can totally hold even the hottest part of this light comfortably for a minutes without the risk of burning yourself. That means most of its power is going into producing photons.Seemingly very economical as well, has not impacted my bill year over year compared to not running anything at all. I think there might be a hidden variable there though.

Great even light distribution and low heat. Dimmer works well and plants are happy!!

800 watts is great for producing large fruits and supplying the plants with energy. The spectrum of the light is fine for the Vegetative or Flower phase of plants and is usable for the entire grow cycle. I really enjoy being able to dim the light if I need to control heat or reduce par output for younger plants. LED technology is a great upgrade from the traditional HPS and MH lamps (more control, less heat issues, wider spectrum, safer.) which is why I would recommend these lights for any home grower but I do suggest using a fan to directly cool the transformer and its connection point as they will get hot.

Great quality…. LG driver to power the light….Evo Samsung horticulture diodes …. Quality build…. Nicer than my spider farmer light…. Even par across 2x2 canopy!!! Amazing light for the price point!!!

They were very difficult to get up and running using the software. They work well and are a quality product. If you purchase this light make sure that you purchase the USB controller or you will never get it to work wirelessly. here is the link to it.https://www.amazon.com/dp/B0CT2PVLVN?ref=ppx_yo2ov_dt_b_fed_asin_title

I mean what can I say? This is exactly what I was looking for. This is more than enough for a 3x3 tent. It's actually a little more than most need. I have to keep mine 24 in or above.(Veg) When on 100%. But that's exactly why I bought this light because I wanted better coverage around the perimeter and this is definitely going to provide it. I can tell already after 3 days. This is definitely a commercial grade light. At least to me at a steel of a price. It came highly recommended and I highly recommend it.So update only a few weeks to harvest, this lights great, I am adding 1200-1300ppm c02 in a 3x3 AC Infinity tent, so I am running it @ about 16in @ 100% and it's measuring 72,000-73,000 lux at the very top bud site.If your looking into growing, and you're trying to do it right once like I was. Don't waste your time, just buy this light. Even if for some reason you can't afford it at the moment, wait until you can. Because the performance the price is great. Haven't had any issues and if I do I'll be sure to update. But I am extremely happy with the purchase. I mean let's call it what it is. It's a commercial grow light and it performs like one.

Only just over a year and one side stopped working. Not happy and most likely will not buy Mars Hydro anymore.This was a big investment and for $529, I would expect it to have lasted a lot longer.

It works fines, time will tell how it holds up. They recently updated the app and firmware for the dongle and smart timing and other functions now work correctly with the light.
