Sorry, should have put that. I tried without optics, from a few inches to 12" above the water, as well as with 60 degree optics up to 18" above, all have the same effect.

Widmer....I'm not following you. 34 LED's over a 46G tank is too much? Maybe I didn't describe what I'm seeing good enough. Here is a pic....I'll try and get some video as well.
It's as if I'm seeing blue shimmer and white shimmer at the same time.......not sure but I'm not really liking what I'm seeing so far.

anyone ordered from them??? I need another 52 Q5's and 10 more RB. They seem to be the best on price. I have ordered almost everything through Nano customs and group buy but would love to save over 60.00 on the last LEDS needed.

Sorry, just trying to make sense of the "L" and "N" on the datasheet.
Thats all they give you (L & N).
What would you have called them?
For this driver, it really doesn't matter which way you hook it up, it sees the same inside either way.
Too bad we went to a new page right now. I expected more comments on my pics on the previous page.
Since I was running 36 XP-Gs at 700mA and got close to the intensity of a 400W MH, I can now safely assume that we CAN get the equivalent light from 36 LEDs, I just might have to run a bit over 700mA to match it.
Then of course the blues to get to the right Kelvin scale.

Do you have access to a PAR meter?

No, I mean in the first sentence you said White was L, then in the second sentence you said Black was L

Looks like normal shimmer to me. I just put 48x leds @50% over a 46 bow and it looks about the same. If you don't like the shimmer it would be reduced without optics on the LED's

Stu that is amazing. Gues you could even match it with less white plus the kick from blues. Probably adding Blues to that same amount of whites will go over the 400W MH. Thats way too cool :dance:

sammy113,
Your tank looks beautiful!
Sorry mine detracted from that shot... bad timing
The Grim Reefer,
I wish I did have access to the PAR meter, but I dont.

You're only about 80 miles from me round trip, that wouldn't amount to a pimple on a gnats butt to what I've spent in time and money on the T5 tests. If you want to do some readings some time I can take a cruise PAR meter in hand, never seen Longmont.

"If you want to do some readings some time I can take a cruise PAR meter in hand, never seen Longmont. "
I am setting up a small frag tank as we speak(type).
It will have an XP-G pendant over it and we can experiment & compare it to the MH.

P.S. no-one has ever left here without free frags ;-)

I don't have a tank up yet so I will rain check you on frags. I am pretty much available any day so when you are ready let me know and we can arrange a time.

i am very interested in this as are many but i dont exactly have time to read through 150 pages of posts lol.
Has anyone discussed the matter of cost effectiveness? Such as if you were to build a lighting system for a 55 gal tank. When would the system pay you back, 5-10 years?seems as of right now its more economical to use Fluorescent tubes. They have Daylight tubes out there now and are really bright. For instance a forescent bulb (T8 6500k 32w 48" 2800 Lumen) thats 6 bucks plus the fixture which is 13 bucks for a dual bulb or i think around 28 for a quad bulb setup.
I just wanted to make sure everyone knows that i am not bashing the LED sceen. I love the idea and how colorful it makes things, but as far as economical, doesnt seem to be quite there yet to me.

Finally finished my "proof of concept" nano LED build. Pics. Uploading them now. Then I can start on my 120 build.

ok this is what I started with. A 20" nova extreme pro. I had potential to be a great T5 fixture, if anyone would have supported it. Worked great for an LED retro however.
First order of business was to gut the fixture.
everything fit perfect. The nova actually had a convenient mount that my rig attached right to.
And the fixture fired up. This is only at about 450mA
And with 80dg optics, as it will only be 3" off the surface.
I will get a full tank shot as soon as my corals adjust to seeing light for the first time in almost 48 hours.
