Pic the bones of this -


Yeah, I know it ain't your bulb... but I think it's fair to say that the HID loss of lumen is a low manufacturer trick to make you buy, buy, buy

Both my sunmaster hps duel spec bulbs are at least 3 years old and run 365 days of the year

My current bulb is brand new! - A mistake as, when I swapped the existing 400w bulb from the cooltube, I picked up the wrong box rather than putting the old one in - But I also gave the inside & outside of the tube a clean after 5 years of ownership
