I got in my Tek-5 light the other day and thought I would post a review. While this light is for a planted tank, reefers should take note as well. The fixture is 48" and holds 4 54w bulbs.

Sunlight Supply makes lighting fixtures of various types for aquariums and horticulture. T5 lighting was developed for aquarium use, so I figured, what the heck, let's check it out. The Tek 5 fixture comes in two models of various sizes: plant grow and aquarium. After sending in an email about the differences between the two, I got a reply saying that the plant grow model came in black only, had one switch, and included bulbs of either 6500K or 3000K, while the aquarium model came with 2 switches (one power cord) and no bulbs, but you get a choice of fixture color: black or silver. Interestingly, the aquarium model with no bulbs was more expensive than the plant grow model with bulbs. Hmmm....

Of course I got the plant grow and the optional cable hanging system. The fixture does come with a "garage style" chain hanger, but it's not exactly "wife pleasing." I was suprised that the fixture I actually got had two power switches, and came with some nice GE Starcoat T5 bulbs. Man these things are tiny! They rant and rave about their reflectors, so that was the first thing I checked out. They are bent 9 ways, and are very shiny, but have a strange texture to them. The company says it's to further disperse light, giving the reflector a 90+% efficiency rating. They are very well made with rounded edges, and are nicer than AH Supply's. I didn't expect this. Most companies just slap in a piece of polished aluminum.

The fixture was plug & play ready. All you had to do was pop the bulbs in and hang it up! The fixture is very well made, but not quite as slick as some on the market, but it's not bad at all. I plugged it in and blinded myself. Holy cow this thing puts out some light! Much more than I thought those tiny bulbs would! I swiftly proceeded to hang the thing up and get it going. Here's some pics:













After turning it on, my plants began to pearl nicely after about 20 minutes. There was a drastic increase in light...almost too much! And to think they make a 6 & 8 bulb version! About an hour later my tank looked light a champagne bottle on new years eve!

I think anyone needing a good light should check these fixtures out; all those big name fixtures don't hold a candle to this thing. The plant grow model is substantially cheaper than the aquarium version that's sold at some aquarium supply places. I have no doubt that you could grow some nice corals under these things, as well as plants. Needless to say, I'll have plants on the trading block soon...

Avalon, nice green tank! Green with envy here! SO how MUCH was it? We all have to know. I really like the way it looks and that is exactly the kind of lighting I want as you can get in the tank a bit easier, but is there a way to easily raise it?

The fixture was $269 (incl. bulbs), and the optional hanging system was $27. Total was $296 (no tax) and I got free shipping. Not a bad investment considering cheap bulbs (like I got) are $15 a bulb and they last for 2 years or better.

The hangar is really cool. You can easily raise & lower it. The wire is held by friction clips (those things that connect to the fixture). Makes maintenance very easy. :) I'll add a shot later to show how it cleanly mounts to the ceiling.

Avalon, I have noticed you mention a couple of times that T5HO's were developed for aquarium use. Where did you come by this tidbit of information?

They are becoming really popular for industrial and commercial applications due to their advantages over other methods. My workplace has started replacing HID fixtures with T5HO units that pay for themselves within about a year in energy savings. I have been playing with the idea of getting a commercial 4 bulb fixture that looks very similar to the one you got (except it's white). There is also a possibility that they will be changing some ill-placed 4 bulb fixtures with better placed 6 bulb units and hopefully their mistake will be my (and my plants') gain if they will let me have (or buy) them.

Halides give a cool shimmering effect, but also put out a lot of heat. That's wasted energy. The lights at work that are coming down are 1000 watt halides. They are being replaced 1 to 1 with 324 watt T5 fixtures that put out more light (yes, we measure it at the work surface... it's an FAA thing).

Wow, the info on the webpage looks great. Now I see why your selling the Aqualight fixture. For some reason my browser settings block me from seeing your pictures. I'll look at it when I get home tonight.

I think if you got gullwing reflectors you'd get even more light output, but I've only ever seen gullwings applied to single tubes.

Most of the T5 units I've seen for industrial applications (including dentists) are NO T5's not HO. Industrial HO units would be interesting.

For marine purposes I'm really getting to like Halides - it would appear that the shimmering, rippling effect is more than just visually pleasant, but that the repeated increase and decrease in intensity can have important effects on coral health and colour. Nonetheless, and especially with mag ballasts, they are wasteful of electricity
