The Mars II grow light redefines expectations for yield and quality in indoor and greenhouse agriculture. The new 5watt LED grow lights are absolutely the most powerful grow lights on the market today. Watt for watt and chip for chip, best in the world.  It is unnecessary to make low power chips or double lens to focus the weak LEDs on a small footprint. The Mars II is made up of the most advanced LED grow lights. We designed this square light, because you the growers gave us feedback. This more efficient shape works much better than others for square rooms. Truth is everything, with more power, higher wattage, and greater penetration. The Mars II guarantees that your plants will be healthier and happier than ever before.

 Mars II led grow lights; now use the most powerful high output 5watt LEDs. As you know, higher power equals higher temperature. To solve this heat problem. We have integrated bigger, quieter fans that have been tested and are the same decibel levels.  From the following picture you can see we are using better heat sink high grade aluminum than before. You can also see the distance between led’s is wider than the 3watt models. All aspects have been improved, for optimal growth!

So far I'm a very satisfied customer. My package arrived in 7 days, and the lights are very bright. My plants love the light, and I do too. It's the best $200.00 I ever spent. There are so many LED company's out there, and I'm so glad I choose top led lights. Amazing! Almost too good to be true.

Great packaging, and fast delivery time. Very bright light, and sturdily built. After reading so many positive reviews on 420.com, I can't wait to put this baby to work!

I've been using 2x of the 400watt mars 2 LED, one in veg spectrum and one in flower spectrum each in separate 4ftx4ft rooms. My plants have almost doubled in size compared to using a 400watt hps bulb. Each light only increased the temperature about 2-3 degrees per light per 4x4 room. Also my electric cost each month was cut by 65%-75% compared to hps!!!! If you are doubting whether or not LED lights actually work, trust me when I tell you that they are amazing! I defiantly recommended these lights to anyone trying to keep the heat down both for your room and for your wallet!

This is a very heavy duty light, it's rather heavy and very bright. I would certainly recommend it to anyone wanting the latest technology in led, the price is actually amazing and in the world if 5w led panels it can't be beat.

If anyone ever tells you LED's don't compare to HPS or similar bulbs is wrong! These work absolutely amazing. I love the quality of the product and the amazing customer service. Couldn't be any happier!
