Watch for my thread on those LED
's. My units (1-120w Master and two 120w slaves) should be arriving from Poland tomorrow or Friday. When you combine the light output with the control software it's less than buying a top line 250w MH
fixture with similar features. In fact I was offered a 1 year old used MH
for $2800 which is aprox a $1,000 off new. I got these LEDs units for less than that and they can output PAR of a 400w MH
down to 12".
Right now I'm designing the canopy or shelf or hood to hold them. Deciding between stainless or plexi too. Ah decisions, decisions.
Initially I'm going to just raise them about 4" off the surface and remove my 150w fixture.
The savings in electricity should take into account not needing a chiller and annual bulb replacement too. On a 72" tank with 3 MH
and 4 PC
lamps that's a couple of hundred a year just for bulbs.
