Change of plans. What about this over a standard 125g. 3 pendants.
1 50w hybrid 20 20k/30 447-450 run 12 hours
2 20w 10k run 8 hours
Total of 270W total. Is that enough?
How deeps is the tank? Though, sounds pretty good.

for those of you guys running your leds on a controller. What driver are you using? do i need to get one thats labeled dimmable? I have an apex controller and id love to test out my 20watt blue chip on my controller to adjust the intensity. Can someone explain this to me? These are the pieces i purchased and im pretty sure i cant dim this driver on my apex correct? If not which driver would you guys recommend for me to be able to do this?

advice is greatly appreciated.
hi.. does anyone know the result (in my tank with 100cm x 50cm x 50cm dimension) if i use :
5pc

and
5pc
http://www.ebay.com/itm/2pcs-10W-Ac...721?pt=LH_DefaultDomain_0&hash=item19d27e5799
in design like lassef like picture o attach.
are this design was good enough to replace my 2x39W T5 ? most in my tank was LPS.
please help me..
also if i use a 2x50W dimmable driver for each series LED (5xwhite and 5xblue) will it work ?
Generally - 100 watt LED replaces more than enough 2 * 39 watt T5. My choice would be however five pieces of 16 000 K white and 5 pieces of RB with different wavelengths (445 and 455 nm). I would use the lenses, at least to the white and put the chips in two rows of each color separately.
It is difficult to find a perfect drive for 5 * 10 watts. If you go down a little from the maximum current of 1000 mA thera are some including the HLG-40H-54B, which would give about 80% of the effect (about 40 watts)
Sincerely Lasse
thanks lasse..what lens do you prefer to use ? are 60 or 90 degres ?
Depends on. Near the shortsides of the aquarium I prefer 60 degres - in the middle with your deepth probably 90 degre will be great. But there is no must, but its good if you get the light there it should be (inside the aquarium) and not on the glass.

This is DIY. Saving cash is part of the satisfaction. Flexibiltiy is a big part of it too. For me, power output more than makes up any shortcomings even if the build cost was equivalent to a Kessil. It's not for everyone. Part of the attraction of the multichip LED light point source is to get away from having to wire up multiple smaller 3W LEDs. To quote someone who's built mutliple 3W fixtures, "And so much less annoying then the 3watt builds (I've built 5 or so 3w fixtures and they get annoying)."
Like I said, it's not for everyone.
thanks you Lasse.
so..you means to separately 5white LED in 1 rows and the other 5blue led in 1 rows ? about the driver,can i use 50W driver if each row i build the led in series ?
if yes,then i need 2 long heatsink like what you build in picture.can you tell me please,where you get the heatsink ?
no I get it, saving cash is great, I just thought it would be more of a cash savings.
Lassef i cone du another build fore diffrent tank 48x24x20 inch i was think two pendants each vith 1-50w multy chip , 2-10w 10k , 2-10w 16k , 4-10w RB, should i need add any UV led vhot you think thanks for respond.
That's a pretty deep tank. I'd start with a 60W (10000K/445-447 royal blue) hybrid for each section of the tank. Then supplement with a few more multichip LEDs to get each section up around 100W total.
Attached multichip.
