The New Optic LED Slim 600H Gen2 vertical farming LED Grow Light takes vertical farming into the new era.

It is fully equipped with the Latest in High End LED technology from the best of Samsung, the best of CREE and the best from Meanwell. The Slim 600H Gen2 is a massive 41 by 42 inch fixture which delivers uniform light intensity and promotes uniform growth across your canopy.

Dimming gives you full control of your intensity and allows you to only use what you need, taking efficiency to the next level, reducing BTU output and extending the lifespan of the fixture.

The Slim 600H is for growers who want to grow with the latest and greatest LED Tech from Samsung and their new Horticulture specific line of LEDs. It is the first vertical farming LED to feature Samsung's LM301H LEDs in a high powered fixture that flowers a 4x4 area or bigger.

It is also the first to deliver over 4.5 LEDs per watt with Samsung LED Tech and the first to be engineered with a ppf/w rating of 3.0 umols/j. Imagine what a Slim 600H can do for your grow!


Optic Slim 600H Gen2 Features

  • Samsung LM301H LEDS: 2688 diodes with a mix of 3000K and 4000K white light; driven at 200 watts total (2.4 LEDs per watt)
  • CREE XPE LEDs: 24x 460 nm royal blue and 48x 660 deep red
  • 120 degree lens: each Samsung and CREE diode has a 120 degree lens for protection and to focus the beam for better efficiency
  • Meanwell driver: top of the line MeanWell HLG Series 600 watt dimmable driver
  • Large coverage: 4 by 4 feet
  • Dimmable: dimmer has 4 possible settings of 25%, 50%, 75% and 100%. Note this is a single dimmer which means that all spectrums dimm together.
  • Yield: Up to 1200 grams / 42.85 oz / 2.67 lbs (2 grams per watt)
  • Highly efficient: 600 watt power consumption (at 100%), but is equivalent to 1000 watt HID
  • 10-year warranty: you'll see other stores call it a lifetime warranty, but read the fine print...it's 10 years
  • Controller Port: use Optic's 7" Touchscreen Optic LED Master Controller to control light(s) remotely (but not required, you can also use the settings directly on the fixture); add the controller option above to save $100 over buying it separately


Top Quality LEDs And Driver For Incredible Power

The key to unleashing the full potential of Samsung's Vertical Farming LEDs is the number of LEDs used per watt of electricity. Most companies are using 2.5 LEDs per watt or less, which only unlocks a portion of the full potential.

The Slim 600H uses over 4.5 LEDs per watt which increases cost substantially but also delivers industry best efficacy for LED grow lights using Samsung LEDs at 3.0 umols/j.

Double Row LED strips with 2,760 LEDs all being under driven to max efficiency to deliver next generation Par efficacy and a mind blowing 1200+ ppfd at 10" and 12".

The Slim 600H integrates USA Made CREE XPE Red and Blue LEDs which are proven to be the most efficient bloom enhancers on the mainstream market today giving you a balanced spectrum that can be easily absorbed at higher intensities and allow you to get the light as close as 10" from the canopy.

It also uses a dimmable Meanwell driver, which is the best in the industry, to drive the CREE and Samsung LEDs.

It is cooled by passive heatsinks, so there is no noisy fan. It delivers an incredible amount of light and covers a 4 by 4 area.

The PPF per watt is 3.034. The PPFD at 10 inches is 1264. The following table shows the PAR footprint over a 4x4 area at 10 inches:
