What does everyone think of T5's for reefs

[trilinearmipmap]

I am going on 3 years with my T5-lit 120 gallon tank 48" x 24" x 24". It is an 8 x 54 Watt Tek Light.

It is a mixed softie/LPS/SPS tank.

The light is too bright for some softies eg. mushrooms will not grow.

The sps have done fine however I only have the easier sps for now Monti caps Monti digitata and horn coral. One Monti cap frag I got about two years ago was 1" size now it is about 10" across with multiple sworls and I have taken quite a few frags off it. I don't know how this would compare to growth under halides.

I am getting a calcium reactor in the next month or so and then I will try some harder sps.
