sorry, i assumed the tank was 30"s like my 30....
but it wouldnt matter either way, the legs adjust to fit just about any tank size. i higly recomend those lights, cuz as far as power and cost go, and more importantaly ease of use, you dont get much better. most other HQI usits are clumsy or not as powerful, and i hate pendants
in other words, im a stong believer in hallide lighting for the best health of the reef, and why half ass it right? youll be happier in the loing run
