I just bought two 36" blue LED strips from Onstate Technologies, (Dan Hsu 604-522-7811) for $35. Big Thank you Anthony (SeaHorseFanatic)
Ballast was another $20.
Dan did all the soldering of the connectors free and it comes with double sided sticky tape. I re-atached one strip twice and tape failed but that is easy fix. The other one is fine.
Removed two HO fluorescent T5 's from the 2x250W HQI MH fixture.
Dan told me that LEDs are 140 degrees 470nm. Even though the LED's are only 0.2W and only 10 watts/0.9Amps per strip (50 led'sx 0.2W) it seems insanely bright.
When LED only are "ON" the tank looks only tad bit brighter then T5 actinics only.
I have 36", 65 Gal so it is not a shallow tank.
I accidentally glimpsed at it shortly and I was seeing yellow dots for a few seconds (imaginable)
I noticed that on top of usual green coral color "pop" it seems like zoas are opening quicker to these LED's. Red Gonioparah is glowing red ! But it can only be seen when MH is "OFF" still nice though with MH on as it is still brighter red. As well as superman monti red glow even in the shade.
I have 4 actinics in the fixture and 2 were replaced with LED.
With MH is "ON" I can not tell the difference between T5 actincs and/or LED combined with a MH. When i turn LED's "ON"&"OFF" quickly I can see that with LED's tank looks brighter/bluer. Some people may find that it is too blue, but personally I like it on the blue side.
I tried making pictures but they turned out horrible and do not really represent true likeness of the light and color. Already thinking about replacing the other 2 T5 actinics with these blue LEDs but it may be way too blue, so might go with one extra white strip to compensate (counterproductive), the only thing Dan has only 7000k whites no 10k's.
i asked him if he has any higher power LEDs in stripes but he does not have any.
Other LED's are also in 470+nm range
