Has anyone done any testing with a lux meter to see how T-5s hold up over time? Such as on a month to month basis? I'd be interested to know what (if any) the measurable rate of decline per month is on normally driven T-5s.
I originally entered this thread, probably around page 6 or 7 maybe? last August. I've been running my T-5s, mainly ATIs for 11 and 12 hours a day, every day for 8 months now. A couple inches of them on the ends are getting pretty dark with no light coming out of them.
They still seem to be burning reasonably bright. I have wiped the salt splash off of them a few times and cleaned the reflectors. One cleaning just recently.
I guess my question is..., to me they look bright, but I'm wondering how much they may have lost over 8 months? I'm wondering how much spectrum I may have lost.
I recently bought a very dark blue/green acro frag with green polyps. Since I've gotten it, it's completely changed color. It was under VHOs and is now under T-5s for the last month and a half. It's turned a light purple color with brighter tips and the polyps are almost transparent, although they don't extend very much.
I'm wondering if I have too much light on it or if I'm losing light now which may cause this?
