Pre-planning for upgrading the 8'er, some input on LEDs needed

They are also the same fixtures that are being sold by SWC on their web site. Does this help you with being able to recommend or not? Thanks!

Well its using XREWHT-L1-Q5-0000-00D01 3W White.... XREROY-L1-D3-0000-00703 3W Blue

10 of each, with 60 degree optics which is good.

The only issues I see with it is its using some older models. The XRE are much less efficient than the XP-G and XM-L

Also the XP-E royal blue bin its using is very low end. For instance, the one they are using is 250mW flux and the one that we carry and most of the DIY sites are starting to carry is basically two models higher which runs at 350mW flux.

Its better than most of the ones Ive seen. And your corals should do good under it (SPS, etc).

Thanks for getting back to me. I think I'll try one out (it's only $275 including shipping directly from Eshine) and maybe contact you in the future about DIY for a new 6' tank I'm planning as soon as my house is finished being built. I really just want to feel the waters before I invest further into something I don't care for. A LFS had a cheap unit on display in the store last year and it gave me a headache to look at the tank for more than a minute or two, scared me off LED's a bit.

Can any one tell me how many 3w LEDs ( 1:1 cool white / royal blue ) I would require for a 96"L x 24"W x 30"D tank. I am thinking of using 12" x 12" heat sinks.

Any input would be greatly appreciated.

3W LEDs arent all made the same.

I can tell you that if you go with XP-E and XP-G CREE LEDs you will need about 150 total LEDs.

If you go with CREE XM-L CW and XP-E Royal Blue then you would need something like 90 Royal Blue and 30 Cool White.

Going with these, Cree Part Number: XPEWHT-L1-0000-00F01 & Cree Part Number:**XPEROY-L1-0000-00A01.

If I go with the 12 x 12 heatsink, I am thinking I will need 4, each should cover a 24" x 24" area.

Hey Grizz, have you checked out modularled.ca? They have an awesome website and they're right out of Red Deer.

Are you sure you got the Cool White correct? that is an XP-E not XP-G that most sell, didnt think anyone purchased the XP-E CW.

Both of those are about 82-85% as efficient as the recent XP-E RB and XP-G CW.

Taking that into consideration you can get away with about 180 on a mainly SPS tank.

I would recommend going with 60 NW and 120 RB though because that ratio is more aesthetically pleasing. In pods of 3 to do better color rendering.

Yes I am sure I have the cool whites correct, came right of the web site I am going with. Currently they don't have NW LEDs but I want to go with this company because they are local and I can see what I am getting before I buy, actually physically hold things in my hand. Screw it...... Going with MODULAR LED

Going with only 3 pods would only give me a 6' coverage on my 8' tank.
