We bring Dual Arc grow light bulb technology to the Hydroponics grower. A dual arc bulb incorporates a 400W MH and a 600W HPS arc tube in one bulb, that runs on a single 1000W HPS Ballast. By combining lamp types in one grow light bulb, the gardener achieves the most balanced light spectrum for plants available from any bulb.

 

With an initial output of 110,000 Lumens, this Dual Arc MH/HPS grow light lamp is easily a match for any HPS bulb on the market. If you would like to maximize the potential of your plants, this is the bulb for you!
