light suggestions for TL550

Reports indicate you need Up to 3x more brushwood leds as you do crees

I know but when I look at them side by side in my hood its hard to really tell the difference and I understand the PUR is not exactly the same as what we see but even my corals haven't shown a big difference since I added the crees.

White creed are also rated for 1500ma bridgelux 700ma I think. On my own tank I can't see much difference in light from the cree between 60% or 100% but my corals do
 
Mine are Xp-e similar but max driving current is 1000ma on mine.
 
In a Tl450

Temp normally a stable 25C
 
wow very nice mod, still doing some research, at this point now, looking at doing a cree led diy into the hood of the TL550, hoping top find somehwere local i can get a heat sink or something i could use as a heat sink.
Thank you for all the replies and help and advice so far guys

It may be that they are not at the max driving current.

the bridgelux? if you run them over 700ma they will burn out..

No I mean the crees running under max.
 
Yeah I guess you right, cant wait for dual core leds.;)
 
LEDs are the best lighting to go at the moment, thats without any doubt, Choosing the number and the color of LEDs , First depends on your budget, secondly on what you want to keep,
I can see you want to keep Clam in your tank, remember for keeping a healthy living clam you need the maximum lighting possible for your tank,
I'm sure you understand the difference between CREE and Bridgelux from different advise given above, i would strongly suggest CREE for any LED build (i haven't used bridglux but i believe they are one third of CREE's power)
I like to make provision for future so i like to use maximum lights possible for the tank and adjust depending on my Tank need,
You can put any thing between 14 to 24 CREE LEDs in your tank, going with more gives you an option to use different colors, which brings more colors out of your LEDs, and also running LEDs on lower current, makes the chips lives longer and minimizes the amount of heat generated (you still need at least one fan for your hood )
each meanwell 48P (controller compatible ) can support upto 14LEDs, if you decide to go with more LEDs 2drivers max. is enough for your build,
I recommend using Typhon controller (its not essential for your build , its more for personal convenience ).
I hope i have added a bit to your knowledge about LEDs ;)
 
Shot for all the top notch advice guys. If I should go with 2 drivers, I can have 28 leds, so how does one decide one how many of each colour to choose? Must one have an equal amount of blues and whites? What other colours are there to choose from?
Will be stripping the tanks hood tomorrow hopefully to see what size heatsink I am able to fit in there.
Have any of you guys any idea what the 2drivers,heatsink,typhoon controller and 28leds would cost? Just a rough estimate?

Sharp,ima shower quik and be on my to sams.haha.
Enjoy
