Highly-Efficient LED Grow Light
Mars Hydro SP3000 LED grow light consumes only 300 watts but provides 824 umol photon flux per second to indoor plants and has a high PPE of 2.8 umol/j, saving 25% of electrical power compared with HPS lights. It’s installed with the plant-centric diodes Samsung LM301B to boost the accumulation of plant-based phytochemicals. SP3000 is the upgrade version of SP250.
*Best fit for a 120x60x180 cm grow tent, supplemental grow lighting situation, cultivation with high trusses, and greenhouse grows.
High Light Penetration
Mars Hydro SP3000 is mounted Samsung diodes on a single light bar, so its light penetration is strong enough to bring photons deep down to the branches in the shadow. And with the deep red of 660 nm wavelength in the spectrum, the light is able to penetrate through leaves and carry much energy. Thus, for cultivation rooms that have high hangers or high trusses (for example, greenhouses), SP3000 is the best grow lighting option.
Special Recipe of Sunlike Full Spectrum
SP3000 outputs sunlike full spectrum lighting, very good for all types of indoor plants. Enhanced the red light in the white light to make the SP3000 grow light perform well from seed to harvest for the full cycle of plant growth.
Dimmable Grow Light & Daisy-Chaining
SP3000 is a dimmable grow light that is easy to switch on/off and adjust the light level via the dimmer, which can help indoor growers easily meet the changeable PPFD requirements of various plants from the seedling, vegetative and flowering, to the fruiting phases. If you have multiple LEDs, the mars hydro SP Series can be daisy-chained in series with one another so it’s convenient to control them with one master LED light. (up to 30 lights can be connected)
Thick Finned Heat Sink & Passive Cooling Designs
The Mars Hydros SP series has a large aluminum heatsink with dozens of individual fins that quickly draw heat and disperse it into the air, keeping the LED lights working at low temperatures. A detachable power supply with a 2-meter-long extension cable can be mounted remotely on the side of a grow tent/rack or on an adjacent wall to remove heat from the growing space.
Safety Certified & Excellent Customer Care
All Mars Hydro LED grow lights have been CE, ETL, RoHS, and UKCA certified, safe to use worldwide. Mars Hydro officially guarantees 24 hours customer service, a 5-year limited warranty, and local warehouses & repair centers to offer the best after-sale services to growers around the world.

As the first light like this or me I’d say I like it. First off it doesn’t get as hot as some of my other grow lights. My seed started trees are growing well, and will soon go outside.

Easy set up. Brightens a dark shelf & let’s me buy more plants!

“I have only had these for a few weeks, actually I have had 1 SP3000 for 3 weeks and I added the 2nd one a week ago. On 1/2 of my 4×8 text I have a Spider Farmer SF4000. 589$ light that is designed for 4×4 flower or 5×5 veg. By all means a pretty good light from all the reviews. I bought the 1st SP3000 the days before I flipped these 7 plants to flower. The first 2 weeks of flower I had 3 plants under 1 SP3000 in a 4×4 area. 4 plants were under the SF4000. I added the 2nd SP3000 to run next to the other 8 days ago, and moved 1 more plant from the SF4000 to the Mars Hydro side. The pictures are there but I am not even sure they do it justice, the difference is huge. 1 week under the 2 lights and I can’t tell the difference in the one I moved from the other side. All 4 are growing bigger buds then the Spider Farmer side. Ever the buds directly under the SF4000 in the hot spots still don’t match the Mars SP3000 buds. Yes, 2 SP3000’s cost 200$ more than the 1 SF4000 but the yield difference is gonna be huge.
Look the the PAR map, that thing is legit amazing. I am soon going to get an apogee par meter and verify…but right now the results are right there in buds…good for you MARRS! These lights are awesome.
I am considering a bunch of these for the new grow room I am building. How about a Black Friday sale Marrs? You cheap jerks would not even let the discount codes that can be used on your website work on Amazon…kidding I love you but seriously…give us a sale!”

Just a perfect light for tent! I have a 5×5 tent and had this light and another one from a different company. The ones under the Mars light grew much fuller and produced more than the ones with the other light. I will be purchasing another Mars for my tent. It emits enough just the right amount of heat to keep it warm enough on cold days but not too hot. I purchased this after researching par test videos, and it was clear this was the best value for my money.

I’ve been waiting to review these lights until I saw some results, these plants are 2 weeks into flower and look pretty decent. I’m waiting to see if they come out as good as they would with an HPS, but so far, so good. They’re definitely brighter than a 1000W MH, but they’re so white, that’s the only thing that has me thinking the HPS are going to be better for flower. The put off very little heat though, so you won’t need an air conditioner to cool the tent like you do with the old schools. You’ll save a lot on the electric bill too, probably at least half since you shouldn’t need the AC unless you’re trying to make them turn purple.

Worth every penny!

This is a great light!! Initially, I had an issue with it. It was consuming less power than advertised. So I contacted customer support and they explained various reasons why the power consumption off the wall could be different. They guided me step by step on how to unmount and change some settings for better performance but when explained I was not very tech-savvy they sent me a replacement without any issues. The company & its customer service were quick to solve my issues with their product. SOLID !!! The lamp itself its also great. I’ve been vegging with 60% power and my plants seem to love the light. I would recommend.

Don’t think about buying this, just do it. Your plants will love you for it. 50% power for veg, and increase to 100% during flowering.”

Adjustable lighting is a plus. These lights have really amped up the growth for my plants. Light hangers are a bit wonky, just make sure you have enough clearance above plants. Great buy and SO worth the money!
