agreed... but I dont see what all the hype about t5's being more energy efficient is for!?

If your using 250 watts towards light your getting 250 watts of light output... Roughly we are turning the 250 watts of electricity into photons. To measure this efficiency, we rate PAR. look at this article now... watts are almost the same, PAR is still lower for t5!

I myself would not give a hoot in hell with a $100,00 kicker added on for all the T5 ever made , I guess if you want to keep corals they will work ? But time will tell that also I recall the early in 90's and wow P/C's keep any corals you want yes Huum Power compacks LOL

Until a better ligting is cheap enough I'll keep my M/H and VHO's I hvae had several of the LED solairurs to crap out also at several K$ a pop crazy
I'll stick with what I know to be proven and over many yrs .

But I'm guessing your t5's will most likely be used for Actinic sublimation ? Thats all I use my VHO tubes for . I run 20 lamps just 6 hrs a day and the VHO from 6:30 am till 10:00 Pm .

If you want data like PAR, color temperature, efficiency, or a plot I can help you out
I've seen Iwasaki's and was a bit weary since it's not a name I've heard get thrown around a lot. I guess that's because I haven't been in the MH world for too long. The tank will be a mixed reef as the contents of my 29g will be moving. Acans, Pocillopora, Birdsnest, Montis, Acros, Trumpets, Torch, etc will be going in there. I was told 14k would be a decent mix for them, but I welcome all opinions.

If you have just the simple 1/2 U shaped parabolic then I'd say 10" tops Hamilton's simply use the Magnatek or Advance Iron core ballast I have replaced a ton of them in their little boxes . It will do fine thats all the ballast/transformers I ever ran , I have ran many test using one or the other and there are just to many variables to say this one is better then that one . The electronics are a little better and more efficient but a 35.00 one like I run last 20 yrs and I have never had a electronic to last all that long.
I have these that just came in. Sunlight Supply Reef Optix 2 reflectors. Thanks for the advice, Tangster. I'd like to think Hamilton is around for such a long time.

The color temperature will change based on the type of bulb and even the ballast you use. Im surprised you havent heard about iwasakis... they are THE lights for growing corals (just not good color at all). If you want to stick with 14K I would say Phoenix, Ushio, or SPS... all good for this color

If you dont mind the extra price, go with lumen max reflectors... i promise you will be more than satisfied!!!

I'm not concerned about color as much as I am getting the right light in to my tank. I mean, we all like a bit of blue in there and I suppose my t-5's can help out with that. Iwasaki should still be the one to go? If so, what color temp would you recommend?

Those LumenMax's look great, but they won't fit in my canopy. Those things are freakishly massive

they have different sizes, even one for a nano tank!

But i pulled some charts for you:
Real yellow color
http://i304.photobucket.com/albums/nn185/trentdingo/Iwasaki.png
Nice crisp white
http://i304.photobucket.com/albums/nn185/trentdingo/xm.png
http://i304.photobucket.com/albums/nn185/trentdingo/ushio10K.png
Medium blue
http://i304.photobucket.com/albums/nn185/trentdingo/sps10k.png
And darker blue
http://i304.photobucket.com/albums/nn185/trentdingo/Phoenix14k.png

The charts show how much of each wavelength is emitted from each light

Ah, I'll have to look for one small enough. Thanks for the tip.

What I'm seeing from the 10k bulbs is that they seem to still have a bit of blue in the 420nm range. Is that visible? I do like the fuller spectrum they provide.
