Ok. The LEDs came today from the group buy site. Very pleased.
The solder pads are smaller than I expected. What gauge wire are people using for their led interconnect? |

Anybody think these would work? http://www.rapidled.com/servlet/the-...lbs/Categories
I have a 125 gallon 72" long 24" deep. I'm wondering if these would work and how many I would need? You could make a rack with sockets in it for however many you need. That way you could buy one every couple weeks. Say I started with 2 That Way maybe I could get my first piece of coral. If they would work how far from the surface should they be. Probably a Hair brain idea but I would try it anybody thought I could get by with six of these. Could always split them later. Anybody give me your thoughts. |

Does not say what type of lenses are on them. BUT from what I understand PAR bulbs tend to be more spotlight than most fixtures. So if you want even coverage you actually need more LEDs than with most fixtures. No if you only want a few corals or in limited location maybe that would work for you.
But a standard 72 will need 50-100 3 watts LEDs (according to the DIY numbers) that would be 7 to 14 of these PAR 38s.

So what have DIY folks done for splash shields to prevent salt spray from getting on the electronics? I was thinking of using a few standoffs from the heat sink and mounting a sheet of acrylic to it that is an inch all of the way around larger than the eat sink.

That would work, or mount them 2 or more off the surface and uses lenses.

Anyone have any experience with the Thomas Research drivers? I saw on their website they make a driver thats 0-10v dimmable in the 200w Series (TRC-200S140DT). I was looking to try and wire one of these up with some XM-Ls in series. Also, if at all possible, I want to avoid wiring in parallel since I really don't want to balance out strings, use fuses, etc etc etc. Any good high voltage drivers out there that would let me do this? Also, what are the draw backs to using a high voltage drivers besides the obvious that if there were a short, I could get zapped pretty good. On that note, could I run a wire down from the heatsink to a ground to prevent me from getting zapped if I touch the heatsink?

fns,
not just a good zap, but maybe death. kcress did a good post on the danger of high voltage. But basically the way I (and I think most) took it was that anything over 50 volts we need to be really careful with. So IMHO that would me covering each connection, grounds, fuses (still, but really really very fast blow), and who know what else. Thanks, I will just balance the strings. But some here did a real nice one, but he understood all the risks.

Danger is the thing and not recommended...just use Ohms law and solve for I, use 1 Ohm, and change the voltage between 48V and 200V and you will see the danger.
You could get zapped pretty good with 48V....200V can be fatal. Quote:

Is 48 Cree LED too much for a 55 gallon (30x18x24) with ratio 1:1 and 4 UV ??

Amnezik, I have 48 over a 75 at half power and they seem ok. Get dimmable drivers and you will be able to make it work. 36 might work. Lenses also play a role, but I am not sure what kind yet.
