The Optic XL 1 features a single CREE XLamp® CXB3590 COB LED. It is one of the most efficient lights on the market, delivering a full 2.10 umol per watt.

While the standard Optic 1 is driven at 54 watts, the Meanwell driver in the XL drives it at 100 watts, generating twice the output (see the PPFD charts below). This extra power results in yields of 7.14 ounces (200 g), which means up to 2 grams per watt.

The XL 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.

Optic 1 XL 3500K COB Grow Light Features

  • XLamp® CXB3590 LED Array: brightest member of the second generation of the CXA family; up to 30% higher efficacy and 20% higher lumens than first generation
  • 3500K CREE COBs: warm white light that is great for all stages, but especially flowering
  • Meanwell HBG-100: 100 watt driver means twice the power of the standard Optic 1
  • Grams Per Watt: Up to 2
  • Yield: Up to 200 grams / 7.14 ounces
  • Large coverage: 2 by 2 feet for flowering and 4 by 4 for veg is larger than similarly-sized lights
  • 50,000 hour life span: 8.5 years at 16 hours per day
  • 6 foot power cord: ships with the standard cord for your country
  • 10-year warranty: you'll see other stores call it a lifetime warranty, but read the fine print...it's 10 years

Top Quality LED And Driver For Incredible Power

The Optic 1 XL uses a Meanwell HBG-100 driver, which is the best in the industry, to drive the CREE COB LED at 100 watts.

It is cooled by a passive heatsink, so there is no noisy fan. It covers an area of 2 by 2 feet for flowering (4 by 4 for veg) and delivers an incredible amount of light.

At a 16.5 inch hanging height, the PPFD over the 2x2 coverage area is 549.

Perfect Full Spectrum Light For Flowering

The 3500K COBs 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.
