I posted something on this a while back and most of the responses where either can’t afford it or just too expensive. But because I got bored I started comparing this light with option #2 and #3 on lighting my 300 DD;

Option #1 ATI Light $1,469 with lamps
Replace lamps each year $250
Cost for power usage per year $306
For 5 years (ELEC)$1,530 + (Lamps)$1,250 + (Light)$1,469 = 4,249 + Tax

Option #2 Canopy with MH and VHO
Canopy from Marineland $500?
3- 250 watt MH ballast, lamps and reflectors $750
1 – 160 watt VHO Ballast and Lamp $100
Total $1,350
Replace lamps each year $250
Cost for power usage per year $365
For 5 years (ELEC)$1,825 + (Lamps)$1,250 + (Light)$1,350 = 4,425 + Tax

Option #3 Pendant Fixtures
3-400 watt MH $1,050
Replace lamps each year $240
Cost for power usage per year $ 481
For 5 years (ELEC)$2,405 + (Lamps)$1,200 + (Light)$1,050 = 4,655 + Tax

The electrical cost are based upon running the lights for 10 hours a day x $0.10 a KWH

Now I nickel and dime, beg borrow steal so I run my lamps 8 hrs a day and I built my own canopy and had the reflectors and ballast from my old tank but if not the ATI fixture would of made sense.
