The 1000 watt HPS light has, typically, 140,000 lumens. It makes no sense however, to compare this number to the number of lumens emitted by an LED. Lumen is a measure of a light's visible brightness. The brightest light is emitted in the yellow, green and orange spectrums of light. This spectrum is the least absorbed in the Photosynthetic Active Radiation (PAR) zone. Therefore the largest portion of those impressive 140,000 lumens from an HID light is wasted! While the lumen measurement of LEDs appears less than a 1000 watt HPS, Stealth Grow LEDs actually emit a much brighter light in the plant's usable red and blue spectrum.
2-watt Hi-power LED chips are what give Stealth Grow lights their spectacular intensity. While most LED grow light companies use the weaker and less expensive single watt LED chip, we have spared no expense to bring you the highest quality LED grow light available. Our goal to supply commercial growers with the brightest light possible so that they can produce the yields they have come to expect with a 1000-watt HPS.
