thanks

I really like my 250 watt halides ( I personally think you can get 2years per bulb). I also really like my VHO actinics (best color IMO) and I get 2+ years per bulb with them. I also get 2 years oper bulb on my T5s.

All depends on what you want for color and intensity. Good and bad stuff exist in all lighting catagories.

Comes back to the question "what do you want to keep" and "how big do you want to keep it in"?

Had a 75g FOWLR lit by 2-40W NO fluorescents, perfectly fine. Now I'm starting a reef, bigger tank, got a hi light clam, don't think I have any choice other than MH.

Current tank has only been up since spring but working for me is 2-40W NO fluorescents for dusk/dawn effect and evening viewing, 2-250W MHs, thinking now supplementing with either T5 or PC actinics would make things ideal.

Sounds like MH with T5 is taking the lead

[StirCrazy]

Personaly I feel the best bang for your buck is MH lighting with VHO actinics. the T5's I have seen at a couple LFS here have been totaly disapointing.. I guess they would be better than NO bulbs but thats about it.

for pure intensity you can't beet the MH lighting.

as for your question about your 150's they will be fine for a tank less than 18" tall.

Going on 17yr.s now doing reefs and seen many of my friends. Nothing lights like halides. I run T-5,s over my 75. Nice colour and a decent light, however when I put my 175w halides back on, even with cheaper 14K bulbs, the corals look better.

My friend switched his 180 from halides to multiple T-5,s a year or so ago. The experiment is now over & his 400w halides are back over his tank. His huge leathers & other softies seem to be enjoying the intensity.

I did like vho and agree with Ben,s post on actinic vho bulbs. Good T-5 actinics are pretty close but I still think vho has the edge. Also the above mentioned friend had a previous 120g mixed aquarium before the 180. He lit it with 6-110w vho bulbs. That was one of the nicest looking aquarium I,ve seen. Colours were superb, even with sps.

So I guess I agree with the halide/T-5 combo or halide/vho combo for overall best intensity and colours both the corals & overall tank appearance.

My next best, and better cost wise, would be just halides with a higher colour temp. like the 14K-20K bulbs. And to boot, I like the cheaper bulbs like CV,s or SA bulbs.

T5s for me. They run much cooler, and a more even light throughout the tank. Lighting all the surfaces of the corals, not just the ones facing a single point light source. You can play with different bulb combinations to fine tune your "colour". That shimmer effect with MHs is nice though.

To those that were not impressed with the output of the T5 they've seen, do you know what fixture it was?
I have been following the massive T5 thread on RC... somthing like 150 pages... and the consensus there is that T5ho without good reflectors is about the same as PC, but T5ho with good individual reflectors (like sunlight supply or icecap) is stronger than halide. Infact, there are instructions for how to acclimate your tank when you switch from halide to T5ho so that your corals aren't burnt.
For example, I have been told that the 96w Tek fixture over a 30gal tank might be too intense for some softies, but even a 175w halide wasn't too much light over my 20gal. And a more recent post claims that halide drops off quicker as it gets closer to the bottom???
I know that most of what we read on bulletin boards is just recycled quotes from somewhere else eg, how many times have you heard "wet/dry filters are nitrate factories" or "refugiums need lower flow" etc.
I am just trying to make sence of the difference between the majority of what I read about T5ho and some of the members' experience in this thread...
could it be due to the reflectors? Or are all the RC posts just over-hyping T5?
Thanks,

ps - I should add that in the same thread, it was reported that halides with a new kind of "luminarc reflector" are brighter than the Tek T5ho.

I dont find them any cooler than my 175,s. But I agree with the light spread. Big difference compared with 2 halide bulbs over a 4ft. tank versus 4- 4ft. T-5,s.

Chad, I like the output. I think my 4-4ft. bulbs are as bright, as my two 175,s. I would say the halides are more intense in an area under them. I think the T-5,s drop off quicker though.

I have good individual reflectors. And I have bleached sps that were fine under my 175,s. So the intensity is there.
