I've never run halides over an aquarium, and chose to go with T5s over my reef for control of intensity throughout the day ( 8 bulbs on 4 timed ballasts )
I've seen enough LED reefs up close to know I'm very happy with my T5s

Agreed :) Everyone has a "best" that suits them. LED is currently the best for my needs. I just don't think it's the best light shining into my tank. I'm real happy with them and all they can do. But "best" is just too subjective.

Next thread on this will mysteriously vanish, k? :razz:

:pop2:

ha!

that is all......

I chose led due to i like to have a canopy with a open top and the mitras was able to light my 36x36x21 cube. I was curious and i had the money and got a drop awesome deal i couldnt say no too. And as of now its still not hooked up due to a wait til we move. And the other reason i needed 2 lights to light the cube MITRAS i only need one.

i chose other..

i prefer the ambient light in my living room to keep my tank lit , i sometimes supplement it with half a dozen radions( just for the shimmer)

LED VS M/H
 

We are thinking of switching from Hamilton tech MH/T5 2X250 with Geismann 14000k, to Kessil 350's, running on a drilled 90 gallon, but we don't yet have an opinion on which is better, since we havent tried it yet. We are running 2x150 M/H on our 72 gall bowfront, and it is underlit. Might switch both. I ran LED on a small quarantine tank & liked it alot. We would LOVE to see someone elses tank with Kessils or something similar before we put out the cash. And/or hear opinions from people who have tried or seen both.
On a side note, our first salt tank was T5's only, and I liked the colour they gave, but hubby wanted the ripple effect of M/H.

The Kessil is a really nice light. I like how close the diodes are, really limits any color separation. Not sure how many you'd need on a 4' tank, guess it depends on what's in it.

I have 2 Gen 1 Radions on my 90 and they perform great
I've never used MH so I can't say which is better
I have T5's over a recently set up frag tank and they are boring as **** lol

T5 for now.

LED in about 5 years when the technology is better developed for reefing (and my wallet).
