Group LED buy

So I've narrowed it down to what someone stated about 72 LEDs being too bright. So I think that 24 LEDs seems the right move. But here is my question, if my tank is 72" long, and I plan one building a led strip basically, to fill the length of my tank I would essentially have to space each led out by 3". So, would this be too far apart between LEDs? Give me a spot light effect? If I made them shorter would the light not reach the outside of the tank? I want it for colour not par really.... Par helps, but not my main reason. I need some blue. Heeelllllp!!!!!!
Well my halides are about 12" off the water. Give or take... I had planned on building a strip out of heat sinks and attaching the LEDs to the sinks. If I mount it to my canopy I'm about 15" off the water. I would assume the higher the more dispursed the light would be and less spot light effect. Am I correct? I'm just worries I'll spend the money, build it, and turn em on and bam.... Nothing noticeable ....
you are right but at 15" you are goign to want at least an 80 degree optic I would guess
Maybe even tighter
The optics will forcus the light deeper in to the tank ... that will help with par but thats no what you are lookign for it
you just want more blue and more colorful coral correct?

Hey Karl. A picture of your hood and MH setup would be nice.
I think the best route would be a strip of LED in the front and a strip in the back with the MH in the middle.
I would build it out of U channel. The U channel I used works great. It was 1.25x1.25" and .12" thick. It was $20 with tax for 5 feet worth.
Right now I run 20 royal blues but I also run 20k and 2 x VHO super actinic bulbs.....so I would recommend you do at least twice as many, especially considering the bridgelux are not quite as powerful.

My canopy measures 72lx18wx15h. Dead nuts in the middle is a 2 bulb mh retro with crappy DIY reflectors. I def need two good reflectors im losing alot of light bc of this. I have room for a strip in the front and back but towards the back I'm not sure alot of the light would penetrate the tank as it would almost be sitting above the back brace.
So now you think I should run atleast 40 LEDs? Next kit available is 36 then 72. 36 would be better with only two inch spacing and if I hung the u channel I can vary the height. The kit comes with 60 deg optics.... Ugh, I hate trying to make a decision I'll be really bummed out if it makes absolutely no visual appearance whatsoever

it will make a difference... I have a single red led mounted with no optic on each fixture.... I can see the difference in the red colorings in the tank if I cover it up or not.... Gives a real nasty old skool blue/red 3d kinda effect with out the whites tuened on too...
not sure on how blue it will turn the overall appearance of the tank but the corals will pop alot more

i sent this company an email about the heatsinks and better prices here is the reply i got
c/p:
Hi Phil,
thanks for inquiry.
we are located in Hong Kong.
for a 90 leds DIY kit, if you are going to use our heatsinks, it need 3 of 7.1"x15.8" heatsinks.
2 heatsinks carries 36 leds, 1 heatsink carries 18 leds.
Sure, we can offer a better deal for 2 kits, would you please tell do you need the heatsinks?
best regards
Ray

i havent decided,just inquirering as i want led as well but want the best price as well more info regarding the assembly
it appears to me that the lights mount directly on the heatsink?so they have pre-drilled heatsinks not included in any kit larger than 24 LED kit?and in the email i recieved heatsinks come in 2 sizes that holds either 18 or 36 bulbs that are pre-drilled,still havent heard back but they are 12hrs ahead of us so probably not till monday,but im leaning towards waiting to see your results first,even if i lose out on any shipping savings on a single group shipping order

They say the 72 kit will do a 75 gallon tank...however if your going all LED, myself I would probally lean towards the 90 kit. Worse case scenario youll have to dim back the LED's a bit, the leds will last longer, and run cooler, also 90 leds would give a more even coverage.

I apparently do not know how to do math. For my tank, I need

Blob - can you update my order and get an approximate cost for all of us at this point?
After all, money is money.
