Cheng,
I love your level of detail. you put a biblio on a forum post that rocks!

 

[poolkeeper1]

Too much free time on his hands as far as i can tell LOL
Bill

 

[Jennifier615]

So what is the grand total Cheng? I am interested and want to go to the LED's hopefully by the time my halides are due for a change. I would rather spend money on a new fixture with better light output then spend 500 for bulbs for expensive juice eating lights.

Bill

lol it took me like 4 weeks to come out w/ the list. lol
total is around 800-850 or so if you don't count the one time cost.

 

[NeveSSL]

Cheng, check out the drivers from Nano-Tuners. They're much more efficient than the meanwells. They have some for $80 that will do 30 LEDs each. They're dimmable, too.

Brandon

 

[pelagic7]

Too late. hehe thanks for the info thou.

The drivers I got are around 90% eff, I could pay more and get something high eff, than I thought about if I want to pay $30 for $2% more eff? hehe. I went w/ cheap one, 24 per driver just in case I screw up.

 

[NeveSSL]

Cool.

[NeveSSL]

LOL... wow... I suppose RC was trying to have a sense of humor about that site... interesting.

Brandon

waiting for the led... and I don't expect there will be too much heat for the heat sinks, so I only got 2 stealth fans

 

[poolkeeper1]

Hey Cheng, What size tank are you putting this on? At only 4.25" wide you will not get much spread of the light. Or are you putting 2 side by side? Just curious.
Bill

 

[pelagic7]

110g, 48x18x31

I thought about that..

1. The leds will have 60° optics,
2. plus the fixture will be 4.24" wide,
3. My tank is 18" wide.

=>
1. The light fixture needs to cover 18/2-4.24/2=6.88" for each side
2. highet required to cover 6.88" = 6.88 tan60°= 6.88*1.73=11.90"

=>
As long as the coral is 12" or further from the fixture, it will get the light.
In my case, the fixture will be 10" from the surface of the water, so it should be fine...
