I'm not talking about individual products here. I'm sure there are some well designed T5 units as well as some well designed Compact PC units. However, which format is better for my application? For example, I have heard that Compact PC units are generally better because they run alot cooler than T5 units. I have also heard that they are less expensive than T5 units to run and give of just as much light.

So, can you guys give me the pros and cons? I really want to make an educated decision on which format to purchase. After that, we can discuss which brand. LOL

NO T5's run cooler than PC, PC's get HOT!

T5's are slightly more efficient at producing lumens or light per watt.

T5's penetrate deeper into the water

PC's are basically T5 tubes but they are bent around into a "U" shape, since they are 2 bulbs very close together, they get hotter. Also since they are closer together, the reflector cannot be as good/efficient.

Individual reflectors and T5's is hands down better than PC's


Please search around on many forums for Odyssea, as you will find some good and many bad things about them. They are cheaply made, and that listing says T6 bulbs, which are hard to find and I dont think you can get quality bulbs for it.

Also, for a 4' tank, you can find better deals on T5's then any other tank size. That catalina fixture is the best bang for the buck period, its a great fixture!

And no I dont have one, I'm using a T8 shoplight ODNO at this point, b/c that fixture would be too much for my 55G(for me)

Thanks (Speed). That is a very good breakdown of information. I plan on looking into various T5 units today. Is there anyone out there that can give me a breakdown as to why I should use a Compact PC unit?

Also, (Speed)....I have been reading up on those Odyssea units. I must have sent you the wrong link. They do have a T5 unit. However, I agree that they are cheaply made.

well i actually have one of aquatraders t6 light fixtures and luckily have not had any problems with the actual fixture yet. the biggest problem is that i can only get replacement bulbs from aquatraders and they only have 12000k or the pink bulb for freshwater.
i have opened the fixture up to take a look inside and found that the electric ballast was just shrink wrapped and not in any type of case.
when i need to replace the bulbs i'm just going to retro fit it with t5ho ballasts and bulbs which will cost me another 50-60 dollars which will put the total cost of the fixture at about $120. wish i could have gotten that catalina fixture.

I own that catalina fixture. I'm using it for freshwater planted, but I can tell you it's a great unit. Very bright, and not too terribly hot
