I had one of these (57cm):

in my Aquareef 200, nice and bright, waterproof and has the advantage that it's only 12v going into your tank rather than 240v!
I had a 37cm blue one as well; both on during the day, and had the white one on a timer to switch off at night.
These things are pretty cool too: https://www.amazon.co.uk/gp/product/B00JOQA6I2/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
Lets you dim the light if you want to (also has some strobe and other effects too, but the fish might not appreciate it...)
