The Official Asylum Reef Tank Thread

[shilala]

Lance, I've got so many freakin cigars that I can't even find them all. I did buy five or six boxes of "save for later" stuff last week, though.

Now I'm really strongly considering LED lighting for the tank.
Will you guys please take a look at this for me, and see what you think?
Here's where I am so far...
I'm trying to figure out how to get from watts/gallon to lumens/gallon to size my fixture. I already plan on getting the biggest one at that Foster Smith link cause I think it'll fit my tank.
The reef capable lighting are rated for 50,000 hours, which is 17 years of 8 hour days. Right now I run a little over 8 hours, but I need to back that up.
The fixture is $365, you never replace bulbs. In 17 years, I'd spend somewhere between $1600 and $3200 for t5 lamps. I'd also have to replace the fixture at least twice, and that'd cost about $1,000.
So it's t5's for $2600-$4200 or led for under $800. (Apparantly I need two fixtures because these things really focus the lights into a very thin, straight down wall of light.)
With two fixtures, I'd be down to 108 watts from my current 432 watts, so I'm looking at 1/4 the energy use and I'm guessing 1/4 the heat.

Being that I was already going to spill $200 for tubes, I'm really looking at $530.00 to make this upgrade. I'm sure I can sell my 48" t5's on Craigslist or to one of the reefers in my club, bringing down the price even more.

The one drawback is that there's a polycarbonate lens on this thing that creates a "realistic ocean shimmer effect" that is only realistic to people who have never been in the water. It's more like a strobe light cranked all the way up to max, almost constant on, or at least that's how I perceive it when I look at them.
I'm hoping that's more prominent with one light than with two.

Will you guys please take a look when you have time and let me know what you think? I could use a bunch more negatives so I can weigh this out a bit better.
