600 MH Conversion Bulb (ED 25) 68,000 lumens: G
This is a MH bulb that works with an HPS ballast. If you bought a 600-watt HPS lighting system to use during the flowering stage, and now you want to use the same lighting system to grow plants in the vegetative stage instead, then this is the bulb you need. Simply unscrew the existing HPS bulb and replace it with this one and your set.
