The High Power 4S Solid State Sun Spectrum Series are full-spectrum LED grow lights perfect for all types of growing --- from the initial Veg stages all the way through the flowering process (depending on spectrum option). This light only draws 334 watts, but delivers high-intensity light that will replace a 1000 watt MH or 1000 watt HPS setup over 25 sq ft of coverage. LEDs available either in 3200K (tungsten for HPS replacement) or 5400K (daylight for full spectrum growing).

The 4S Series was designed to give customers the ability to utilize technology that performs better than conventional lighting while saving money and controlling cost factors. The Alta LED Patented COB's create a viable light source that uses 70% less energy while reducing heat output by 70%. 

The 4S Series includes a durable, heavy-duty, aluminum housing enclosure and is damp location rated. The stealth look of this fixture brings this American technology to the world with unmatched performance. 

High Power 4S develops products that make less of an impact on the environment and use materials that are not harmful to the Earth or its inhabitants. All products are mercury free.

  • LED dies are the same color, yet are 97% accurate to the sun’s spectrum
  • Fixtures are commercial grade, IP65 rated
