Only 1 watt LEDs and very tight optics so you will most likely have some spotlighting even in that small of a tank. Let us know how you like it and track your results for us.
 
...I'd like to approximate the color I get with a basic T5 mix of 50/50 10k and actinic - I could go a tad more blue than that but am definitely not looking for the "windex" effect...is there any one of these bulbs (Boost/Rapid/Ecoxotic/Nanotuners) that would have that color (and which combination, since some have multiple possibilities), or any two that would mix? If so, which one(s)? Thanks!

Anyone?
 
I've read almost all this thread over the past couple of days, and I think I know the "power" side of what I need. What I'm still a little unsure of is the color. I'd like to approximate the color I get with a basic T5 mix of 50/50 10k and actinic - I could go a tad more blue than that but am definitely not looking for the "windex" effect. I'm not sure what that "temperature" would be and in any event it seems as though the advertised "K" isn't necessarily how they appear. So, is there any one of these bulbs (Boost/Rapid/Ecoxotic/Nanotuners) that would have that color (and which combination, since some have multiple possibilities), or any two that would mix? If so, which one(s)? Thanks!

if you are trying to avoid "windex" effect, you should pick up the "reef" color par38 from wingoled. their par bulbs beat rapid's and acan lights' par bulbs hands down both in the color rendering and par value. when it is on, the "reef" color is very white with very little blue while still providing a lot of "pop" . when it is off, the ratio of the blue to the white is 7:8. i am not sure how many royal blue and blue are in the 7 leds.
 
here is the link of the par38

or you can browse wingoled.com. click on aquarium lights, you can see a host of aquarium lights they make or import. you will have to email them to get the dealer nearest you. I picked up some of their products in ct swap and lfs in new york city
 
i did get the par 38 bulb in, here is a pic with the tank empty with a light fixture on it, has 36 watts, 2 bulbs, one all white, one all blue,

i do not have the par bulb permanently mounted yet, I will be looking into that soon, the tank is still cycling and i just now today put in some softies from my other tank, they other tank had a 175 mh, figured if they adapt and live then they will be getting enough light,
 
Can somebody recommend a powerful 6700 to 10k bulb, with 40-60 degree optics. Also anybody here have success mounting these on an AI rail? Looking to get a little bit more yellow to supplement AI's.
 
I personally don't think it's 5300k. But the only way to know is to try because colors are all personal opinions. One thing for sure. It's powerful.
 
Led liquidators. 12x3w Cree white par38. Kicks ***. It's a 6500k type bulb. IMO not very yellow at all.

Do you have a laser point thermometer? can you test the heat sink temperature after it ran for 3 hours?

Also do you have a PAR meter, if so what's the value at the bottom of your setup?

Thanks in advance.
 
I don't have either of those. I can tell you with the 36w cree led about 12-15" above my tank I have low light stuff doing ok at basically the bottom of the tank. leather, xenia, caulerpa. If someone wants to loan me that stuff.....
 
thermometer on it's way. Always wanted one anyways for cooking etc...now if anyone has a par meter I could borrow....
