I have 3 fixtures shipping monday. Lumatek adjustable ballasts with lumen max elite reflectors. Bet you are gonna ask why? Well here goes (This is NOT an anti LED thread) 1. my lights are getting older and I'm going to need to replace them (or the led pucks at least) in the next 2 years. And I don't have 3 grand to buy the lights I would need. Yes I'd rather buy 3 new bulbs a year 2. I didn't save any money on electricity! I replaced my 3 halides(750w@7hrs) with 4 sol blues(120w@10hrs counting ramp times). But without the heat from the lights my heaters are now working 24 hours a day that's an extra 800 watts banging away. 3. I don't care about the heat they add. My tank is in a finished basement and I have central air. My house is never above 77. It only helps the heaters run less 4. My tank was always at its best when I ran MH so I'm going back. I do get concerned that they will stop making the MH bulb I want (this happened with the Phoenix 14k se) but that's a bridge I can cross later.
