Hey, so I found that site a few months ago and thought I had bookmarked it... I was wrong ;). Anyone know which one I'm talking about? It's got a bunch of drop down menus for selecting different lamp and ballast combo's.

Anyway, I'm getting those 250 watt Icecap's from my other thread, but the lamps are 6-8 months old. So I wanted to try and figure out what I want to do with them. I'm debating selling/trading the fixtures for a single end set up but I want to check the PAR on my options first. Thinking single end for cost of lamp replacement, they seem to be $30 (or more) less than the DE's I'm finding.

Thanks!
Chris

EDIT: The other reason for SE's is I should be able to DIY some lumenarc's pretty easy ;).

Thanks to both of you!

... and bookmarked lol ;)

Any thoughts on what to do with the lights long term? The tanks are 36 x 20 x 12. I was toying with the idea of both 250's on one tank and some T5 HO's or PC's on the other for low light. Buuut really I'm open right now ;).

Fair enough about the t5's. The main reason I'm thinking of that is I've started to get frags and cuttings from other locals and there's been a few I've had to put in my mantis tank. No matter where I put them in my reef they seemed to not acclimate to the light (150 HQI on a 20gal). So having somplace to put items like that would be nice. I guess I could use egg crate or shade cloth off to the side with the 250's though...

Yeah, I started looking at the options for SE's but there's a lot to sort through. He really does know his lights eh? lol ;) You're very lucky to have him in your local club!

So I'm a little disapointed with the results from the Icecap 250... The energy draw is AWESOME but the PAR is kinda lacking compaired to even a normal M81 with the lamps I'm looking at. Here's the best ones I could find locally.

1)XDE 10,000K DE @ 121 PPFD; 7541 CCT and 253 watts

2)XM 10,000K SE @ 115 PPFD; 11,543 CCT and 256 watts

Taking into account price difference, availability, and PAR I'm leaning towards the DE... but the colour has me a little concerned. I have a feeling I'd need some supplamental lights to get the look I like. That means more power, equipment, lamp changes ect... Any opinions on whether or not I should even worry about such a small differance in PAR? The SE is only $10 cheaper so cost isn't even going to be a consideration so far as that goes.
