Sorry I didn't answer all the questions earlier. They come in their own little fixture which is very slick looking. the ballast is contained in this little fixture the fixture it self is about the size of a t 8 bulb and the t5 bulb is quite brite. the endcaps are basiclly mini versions of the larger size ones.

any other questions?

Got any links to sites with specs?

Sorry I don't :confused:
Maybe Des will pipe in here? He is not on here much though

I may be wrong about this, but I believe the Germans are somewhat ahead of us lin lighting technology. At least in how it applies to reef keeping. I suspect thet the new T5 bulbs provide as much light as the electricity sucking MH bulbs we tend to use. Certainly with different phosphors it is possible to create any spectrum lighting you want. :eek:

This actinic t5 I have is a little diffrent blue then my zoomed actinic bulb's are. The zoomed's seems to have a pinky tone to then compared to the t5 which is like a compact flourescent blue color.

I wonder how much deep discussion on the merits of different blues we could get into. :rolleyes:

I recently bought some half blue 13W bulbs from AHsupply. The blue is different than the bulb I bought from Jach Chu..

I suppose there would be any amount of different shades of blue as you go deeper into the ocean, as more of the other wavelengths get filtered out. Then when you get deep- enough it becomes black. :sleeping:

Found some info about T5 units here:

This link does not work for me.

Link works for me Bob, maybe you have to wait a few more seconds.
Good article.
