The PhatSlim One XL Bloom LED grow light packs a lot in a little light

Featuring 360 Top Bin Samsung LM301H White LEDs combined with 16 Samsung LH351H v2 660nm Deep Reds and 2 UV and 2 IR LEDs. It's powered by a Meanwell driver. It is one of the most efficient lights on the market, delivering a full 2.8 umol per joule.

This UFO LED emits a warm white light with a warm color temperature. It is a full cycle light that works well for any stage of growth but with increased resin production from the added UV lights

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.

  • Samsung LM301H LEDS: 360 of the worlds most efficient Samsung LED's providing 3500K white light
  • 12 CREE XPE LEDs: 8x 660nm deep red and 4x 450nm royal blue for a better plant spectrum, meaning larger yields

  • Meanwell driver: top of the line LED driver
  • Large coverage: 2 by 2 feet for flowering and 3 by 3 for veg is larger than similarly-sized lights (2 lights cover a 2x4 area and 4 lights a 4x4)

  • Yield: Up to 291 grams/ 10.4 ounces
  • 100,000+ hour life span: 17 years at 16 hours per day
  • 6 foot power cord: ships with the standard cord for your country

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.


And the PAR data at 12 inches (PPFD 627.43):

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 deep red light.
