The Hydro Crunch grow light system combines our digital ballast which is UL listed and has the ability to dim 600W, 400W, 250W and also has a super lumen enhanced setting to maximize the grow light systems output. Digital ballast lighting systems generate roughly 30% more PAR (photo synthetically active radiation) for every watt of electricity consumed compared to the magnetic (core and coil) ballasts of the past. Digital ballasts are more efficient at turning electricity into light and because light intensity often directly correlates to yield you can expect more production for the same electric bill. The Cool Tube with Wing cylinder shaped reflector comes pre-wired with detachable ballast cord and an E39 socket which will accommodate HID bulbs (both HPS and MH). The 6 in. Cool Tube with Hood grow light reflector comes with a pebbled, polished reflector for ultimate dispersion and reflectivity and can be air cooled allowing you to reroute unwanted heat out of the growing area using 6 in. ducting and inline fan (not included). The grow light system comes with a grounded multi-pin timer to control your photo cycles along with a ratchet light hanger for easy hanging and up and down adjustments over the plant canopy.

Comes complete with ballast, reflector, 600W HPS bulb x 1, timer and adjustable light ratchet hanger
