Giesemann 13k bulbs

[Jim Barry]

I have had my reef tank for over 6 years and have tried several metal Halide bulbs with mixed reviews.

I bought Giesemann 250w SE 13k bulbs for the first time and I think they are outstanding !!

I found previous bulbs to be good in one spectrum, ie blue, but weak on other colors like pink or green. I find these bulbs to have a great balance in all colors and really make my colors pop....


I highly recommend these bulbs
