Ok finally.. I got my lights today from a local reefer!!! The guy was really cool, we talked at his house for like 4 hours lol. he gave me alot of first-hand knowledge hes picked up, and some donts that hes learned. \r\nI got a dual 175 MH with magnetic ballast and 2 vho 48 inch for 0\r\n\r\nI have to buy new vho bulbs. He gave me 2 sets of MH bulbs. 1 set is true 10000K and the otehr set is 12000K. He said he switched them back and forth for a bit until he decided he liked the 10k better. The bulbs are 4 months old. \r\n\r\nHow long do mh bulbs with magnetic ballast usually last?\r\nand should I clean them with alcohol and let them air dry since they've been touched on the way home??
