There is a guy Ive got saltwater supplies from in NJ who had some LED’s on a tank in his basement…he is a wholesaler of fish, rock, ect…
I emailed him a couple days ago to see what he could get for me and this is what he had to offer…
60 watt using Cree XR-E series 10 3 watt 6000 ~ 9000K white and 10 3 watt 450~475nm blue.
With 1> 3 watt Cree XR-E LEDs.
2> Manual dimming feature, control white and blue separately.
3> Switch color control.
4> Fan can be controlled independent
5> LEDs can be replaced after full life expectancy has expired.
6> Digital timer to control the lighting time automatically.
7> Unique design, wiring port in each of side, can be used in tandem.
8> LEDs array spacing, help to heat emission
9> With lens, light-emitting angle of 30 or 60 degrees, more efficient.
10> Five years warranty.

I discussed the spec’s with Jared earlier and he wasnt too thrilled…I’m still learning alot about LED’s, let alone reef lighting…
+1 on tim’s comments. 39 inches /20 lights/ 60 watts/243 PAR. cannot be. i’d question the coverage with 1 light. the ai’s have 8 pucks each w/3 3 watt crees , 72 watts, and there’s no way to cover a larger tank w/just 1.
from cree themselves
“These lighting-class features enable the XLamp XR-E LED to replace many traditional light sources and save money with energy-efficient light and long lifetimes.” “lighting-class” and “traditional” say to me home and not tank lights
no reflectors either in that system, just noticed. the pic w/ the tank also is 2 pics put together poorly
my pic of an ai light w/a bulb missing from each puck [i had to return it] sends out much more than the picture on the site you refer to
I dont know. i figure that model LED might put out 65 lumen per watt. so at 60 watts you get 3900 lumen. a NO 32 watt T8 4 foot lamp puts out about 2800 lumen. a 54 watt T5 bulb does about 5000 lumen? I think.
I just bought a new LED flashlight with a C4 LED that puts out 95 lumen on 3 AA batteries. nice and bright in a narrow focus. probably a 3 w. but its output is dependant on the input DC voltage.
thanks guys, lighting is my weakest point knowledge wise in this hobby…still learning about ‘useful’ light for corals, PAR vs PUR…if anyone has any good light info links they think would help me please share…
Im pretty much sticking around to watch other peoples success in our club with the LEDs before I make the investment. Not in a rush, nor am I usually the first guy on the block with the new toys!!!

And if you wait a year or 2 the price usually drops enough to make you feel good about buying one.

those par numbers are definitely not out of the question. you have got to keep in mind those numbers are with 30* lens, very concentrated beams of light. my leds are getting about 250 on the sand at about 20 or so inhes off the sandbed. and thats with 60* optics. IMO those are a nice set of leds. for that price you can make one yourself and have a few more options but i still think its good. as for success with leds, ive had them since april and ive had some of my corals, some milis and some acros double or triple in size. my ora nathens gren mili has gone from a small frag to about the size of a softball in less 6 months. and my zoas and palys love it.
