LED conversion

!!! UPDATE !!!

Well it’s only been one week since I changed over to the LED’s and so far everything is fine. My clams are opened and look healthy and all the corals are doing great.
I am very pleased with the conversion, be that it is only in the early stage. The temp in the tank stays constant and the fans hardly come on at all.

Paul, I’ve been in contact with the Growlight guy in Canada who is constructing the lights for reef tanks. He seems to stand by his PAR values and mentioned that I can return the light or exchange/refund, if for some reason it doesn’t meet the disclosed specifications.

•2" depth - 1537 Par

•PAR reading 12" depth - 423 Par

•24" depth - 182 Par

Remember corals are symbiotic organisms with algea contained within their tissues so “grow lights” might not necessarily be un-aplicable.

what i said was just my opinion. i do know that what sold me on AI was the 3 watt bulbs and the controllability. if you do get the ones you show, make sure to post some pics for those reefers who might want to follow.

I agree the AI lights are definitely quality. If I was planning a larger tank I would probably purchase from that company. I just don’t see the need for the larger fixture at this point.

for a < 40gal you could also look into PAR Bulbs
if you are looking for pure PAR power I would suggest LED Pacific for looks and still good PAR Orphek PR25UV

The thing I would be worried about with non tested LEDs is that they could be just the right spectrum for growing nuisance algae like when T5’s get old.

nano tuners has the par38 evils par38 for $89

Nano tuners and Evils are only 5 leds comparied to 12 leds on the PR25UV and LED Pacific Bulbs

what are the wattage of those ones? aren’t they expensive like 300 or so

The PR25UV is 12 x 2 Watt emitters with 60º optics price is $220.00 range has best spectrograph IMO

The Led Pacific Bulb they have a few but their flagship bulb is 12 x 3 Watt Cree emitters with 60º optics price is $190.00 range

The big thing to keep an eye on are the new Dense Matrix LED bulbs, like the new DIF-100, DIF-30 and Kessil A150W come with 80º , 90º and 120º optics which will give great spreads with the same or better par and color

Wow I’ll wait then I like 100 optics

It’s been a few weeks now and evrything is doing fine. The only corals I see that are slower to adjusting to the LED lights are my Superman and Sunset montis. Here is a video I took today with the lights.

sweet tank,video,acans,music ::thumbsup::

nice tank/video John.

Thanks guys. I know the video is long, but just wanted to show the colors from the LED’s.

YAY, great to see the tank doing so well. HA??

Thanks Paul, the hair algae is just about all gone. There is a few spots left, but it isn’t doing very well. I ended up removing most of the rocks that were infested with the HA. Also, by keeping my nitrates and phos numbers down to almost nothing, it has just about stopped the growth of the crap.Taking out some rocks also helped to increase the flow in my tank.

John… That is one beautiful tank you have sir ::drool:: Everything looks good and healthy.
