I bought one, then bought two more (so far) - the light pattern on these is the most balanced I’ve found so far. All comparable lights are the same cost/watt. My only complaint is that they could be easier to hang. There are 2 oval openings on each end (maybe 3cm wide) which I found narrow S-hooks I hang directly to the tent ceiling polls. (You could also loop the two S-hooks around a traditional adjustable hanging set but there is nothing on the light big enough to put a clip through directly.) Heat-wise they're very good. Also very bright, don’t look directly at it without UV sunglasses or you’ll likely have semi-blurry vision for a few hours. I’ve got three lights in a 5x5 daisy-chained to one control knob (you still need to plug all three in individually). My first light was an SF-4000 which I was very happy with at first but ultimately on that one I realized the importance of the evenness of PAR and will stick with these for now. I can’t speak to the higher-end lights out there and whether they’re worth the extra money but this is definitely a great mid-range light. You may also want to research Far Red lights that you setup to come on 15 min before normal lights and are on for 15 min after the lights go off which acts like a sunrise/sunset and wakes the plants up whereas supposedly without Far Red the first two hours the plant isn’t really using the light but rather in the wakeup process - same thing at night, plants rebuild at night like people (and actually do the growing at night) but without Far Red they waste the first two hours of darkness. Those lights are cheap, use little power and only need to be on 30 minutes/day. You’d hate to think you’re wasting 1/6th of your electricity and available time while plants wake up from total darkness to 100% intensity for 12 hours then back to total darkness. - You might also try 13.5 hours of light in flower. Between the first SF-4000, One of these lights (750 total watts) and one Far Red I got 1.5 GPW (trimmed and cured) on my first run - hoping for 2+ with 900 watts of even coverage on the next.

This light is excellent. I've been consistently hitting at least 7oz dry with 2 plants in a 4x2x5 foot tent. I recently upped some of the nutrient levels in my DWC buckets, and it has made a dramatic increase in growth. The pictures in this review are my current plants under the Mars Hydro. Based on their growth rate, the should easily top 8oz each. This is a very good light. It doesn't get very hot. You can mount the power supply outside of the tent, because they give you a long enough cord to do so... unlike most other lights. Most of all, it has a very good and even light distribution. The light is almost 4 feet long but only a few inches wide, yet it covers a 2 foot wide canopy very well. The light is worth the money.

I was in search of a good quality light for my plants. I had made an enclosure I have bought 2 mars hydro fans. One is Bluetooth controlled which is pretty cool. My new light showed up an I got it hanging and level. Then I realized it didn't have an on off switch or a dimmer knob. I was a little worried because I thought great now I'm going to need to box it up and send it back. I really didn't want to do this and have my plants in the dark. I decided maybe if I reach out to Mars Hydro we can figure something out or I can just have my timer be the switch and just change the height. I reached out through email and these guys are awesome! After a few emails back and forth and a couple pics they are sending me the dimmer switch and then sent me a link with an installation video. Everything was handled and they are sending me the new switch. No hassle hands down the best customer service I have ever had to deal with. And this light is amazing. There products are really nice I'm impressed 😁

I like the quality of the light. Nice and heavy but not too heavy. The best on the market Samsung chip led's that put out great light. The Samsung led's and Meanwhile driver is a must for me. That made me switch from Spiderfarmer. This SP3000 is the Best quality light I've owned. Only downfall, doesn't have a designated place to use the hooks it came with to hook the light up to the daisy chains. I sat and tried to figure it out longer than I should have. All in all I'll give 4 stars. If it had a designated spot to hook up I would've given a rare 5 stars.

So far so good. The wattage is 286 at the max setting. It fills a 2x4 nicely. I bought a mars hydro ts 3000 and a cheap brand 3.5 years ago. The cheap brand had a led strip go out and was only putting half the power but the mars hydro is still going strong so that's what made me go with mars hydro.

My girlfriend and I wanted a project so we started indoor gardening. Although she's gone and I've given up I still feel I need to leave a review. I've used many lights for my aquariums and sprouting vegetables over the years but nothing like this. They are mostly correct that one SP3000 light will cover an entire 2x4 tent. However, when your plants are really going at it and reaching out toward the light you will absolutely have uneven growth patterns. If you run 2 of these in a 2x4 you can dim them down, have redundancy in case of failure and 100% even light distribution. They run cool compared to sosen driven LEDs or cheaper models. If you take enough caution you can get these about 8" from your garden without burning them down.
