LED compairison article

Good to finally see some info on the multi chip arrays. I've decided to go that route with a DIY project & am gathering the parts in the form of 10 watt arrays in royal blue & 10,000K whites. I already have 4 cool white (6,000 to 7,000K) 10 watters with some heat sinks & optics. Work quite well with a 9 volt battery. Not sure whether I'll use optics in the end or not. I have 10 each of the royal blue & 10,000K on the way and figure these should provide adequate spread over my 4 foot tank. If not, I just add a few more. I see that the multi LED arrays now also come in combinations of different colours on the same chip.

What really shocks me is the ecoray 112 - it has HUGE numbers, with 1 Watt bulbs! Everyone was nono-ing the 1 Watts, but i'm very impressed with the numbers, and the spread. The array bulbs seem to do great as well, very interesting article.

Glad someone finally shed some "light" on this.

OOOOOOOOOOOH YEAH!

In reality the ecoray have the worst spread I've ever seen. People are hanging them 2-3 feet above frag tanks and there's still dark spots between fixtures

from what I have seen, I still like AI, and Radions best I think. but thats just my opinion

ya I still like the fixtures with even spread.... like seriously if you put a coral directly under some of those fixtures they would be toast, but move them to the side 3 inches and its all good... to me thats not a very good setup.... ill take even lower numbers any days of the week... at least I know I can mess with my tank and not burn coral....

Interesting article but I believe Aquarium Reef lighting is more complicated than mentioned, I didn't see any reference to PUR (Photosynthetically Usable Radiation) which is actually more important than PAR. I'm no lighting expert but from what I have read (one or two articles pertaining to Reef LED), allot of PUR light is is not produced by the lower priced emitters (1W etc.) which may appear brighter (to the human eye) and produce more PAR than higher end LED that do provide the PUR spectrums that are required by most stony corals (zooxanthellae photopigments)...

If your up for the read...

I got the article from my Facebook link, personally I didn't understand it all but I thought others might find the info useful and helpful.

Vividaquarium in usa is setting half of their 800 gallon tank mh, other with led radions...using same stock on either side...we will see which is better in a few months for growth.

An excellent article from Sanjay Joshi who is THE acknowledged expert in aquarium lighting for well over a decade.

Thanks for posting it Fishoholic!
