For the first time EVER there ia a LED grow light that delivers results comparable to a 750W HID! The all new Magnum Plus LED is the direct result of time, technology, creative genius and countless hours of R&D. Our revolutionary PARAmp optical technology is now combined with a blinding 40W full spectrum LED. The result is a MASSIVE amount of light from a small footprint!

Or you can adjust color settings based on what crop you are growing for optimal yields. Whatever your desire, you are in full control of your garden! Move over HID and get ready for the new generation of PAR AMP and Spectrol fortified growing machines!

New PARAmp™ Combined TIR Optics

Multiple angles of penetration. This is the key to maximizing coverage, penetration and light absorption between leaf layers.

The new PARAmp TIR Optic features a 105° beam angle for the 40W PARMax LED. The 3W LEDs are then boosted with a focused 78° beam angle. The result is pure photosynthetic bliss... and the deepest penetration known to man.

More Light, Smaller Package

More Light, Smaller Package

The new Magnum Plus delivers more light from a smaller package. This is thanks to our new 40W PARMax LED.

A smaller package makes the new Magnum Plus easier for you to hang, adjust, and position. It means less cost on materials and shipping which equals more savings passed on to you!

I have been using (10) Magnum Plus for two years. You want good bud, vegation, growth, this is the the unit. Now the new unit is availabe the magnum plus 2, I can't wait to get these units to try. If you don't think you cann't afford one of these unit, you cann't afford not to buy at least TWO. Save Electicty, Heat, and mental worry that something is wrong in the grow room.

Great light, great service. I put the light on a light mover, in a 4 x 4 tent. The light mover only moves 18" to 24". I also added 4 T-5, due to the fact my room wasn't above 75*. The T-5s maintain my 82*. This run is 25 (36" tall) plants. I have one month left.
