The PhatSlim One XL Gen7 LED grow light from Optic LED features top bin Samsung LM301H LEDs combined with 8 Version 2 LH351H 660nm Deep Red LEDs and a Meanwell driver.

It is one of the most efficient lights on the market, delivering a full 2.78 umol per joule.

This UFO LED emits a warm white light with a color temperature of 3500K. It is a full cycle light that works well for any stage of growth.

It now comes with a free 120 degree secondary acrylic lens/cover.

It provides additional protection and a more uniform 120 degree beam angle. The downside is that the lens absorbs some of the light, resulting in around 5% lower PAR values.

NEW: we now also have a smaller and less expensive version with half the power. Check it out here.

Top Quality LEDs And Driver For Incredible Power

The PhatSlim 1 XL uses a Meanwell driver, which is the best in the industry, to drive the CREE and Samsung LEDs. It is cooled by a passive heatsink, so there is no noisy fan. It covers a large area (2 by 2 for flowering) for a 104 watt light and delivers an incredible amount of light.

Perfect Full Spectrum Light For Flowering

The 3500K Samsung diodes provide a warm white light that is great for all stages of growth, but especially good for flowering due to more red and orange light. The CREE diodes provide additional red and blue for a bloom boost.

This is a awesome light

This is a awesome light I'm using it now with no complaints at all, if it was anything I could change at all I would make the dimmer switch where it could go outside of the tent but it's no big deal and again the light is awesome and I like it so much if I wasn't living on disability I would have one more next to it in my 2×4 but I'm blessed to have the one I do have..... thanks so much for a awesome light...
