New Study by Sanjay about LED Lighting

[charlie]

Thought this was most interesting:

Advanced Aquarist's Online Magazine - Feature Article: Quantitative Comparison of Lighting Technologies: Metal Halide, T5 Fluorescent and LED

[twisted]

that was good reads charlie...i've been doing alot of thinking and looking at led's. more so for a diy on my new tank build...but it was cool to read there may be something better for the future.

I was reading another article and I think you want to keep an eye on depth, as always. I am not sure that the LED will get good results deep, but with enuf space on your LR to mount coral higher up................you see where I am going here?
I have been waiting for 3 years for Sanjay to come out with something on LEDs.
I heard him talk in the Tri-Cities then and he was not impressed then. He has obviously had the time to give us something worth reading.

Now hang on just one darn minute here!!!

I just spent over a grand on a T5 light because you and Parrot bullied me into it and now you're goin' and gettin' all sentimental about LED's on me!

I guess it's OK... The same dang thing happens every time I buy a new TV!!!

never mentioned a darn thing about price metal, which in my experience is prohibitive

True, those LED fixtures have always been extremely over-priced, very neat tech though....

There used to be a guy over in Lexington who swore by LED's... He had a bunch of those Solaris fixtures hanging throughout his shop. Every time I went in there and mentioned anything about lighting he would pull out his par meter immediately and start saying "look at this" while he went around to each one messing with all the parameters.

Anyway, I guess he was trying to sell me one of them and he was doing a good jog the first time until I asked him what one cost... I think he got mad when I laughed but he seemed to be somewhat used to it. That was when Solaris first came out and I was still keeping discus so it's been a while and at that time the price of one of those hoods was like 5K+, I wanna say they were even more, but since then both he and Solaris have gone under so that should tell us something.

I will admit though that he was able to give a pretty good spiel with that little par meter and the adjustability of the lights themselves are amazing. Any one of the hoods he had would simulate several different geographical regions supposedly (barrier reef, fiji, belize, etc) from daylight to dusk. Pretty neat but I didn't really know enough, still don't, about PAR and what not to get too excited about it back then.

I built an LED hood with basic electrical knowledge for a 37gal for under 300$

I was hoping you would chip in here Steve

Yes Steve, I was/am very intrigued and impressed by your build thread and hope to try myself one of these days. Very good and innovative work there IMO

Thanks so much for including us in the build!

I just finished my LED fixture with Cree LEDs Looks amazing! PAR levels should be good for all Corals too!

ive just contact a friend of mine in hong kong who sells led wholesale but i forgot its there new year so wont hear back from him till about the 11th ive looked over hear in the uk and your looking at around £300 a unit and for a 4ft you would prob need 3 how ever i think from but from him before he can noramly get about 75% off retail prices will let you know if and what he can get
