but for those famous brand ones, are they designed for tank use? and I would suggest you to put a transparent cover below the light to prevent water spilling from the fishes, you know that fishes are naughty some times...especially those shrimps...they like jumping very much...hohoho

And then you should really put good ventilation inside the lamps to prevent overheat from both the lamp and the transformer itself (heat hurts the lamps, the transformers, and water too)
Good Luck!

Of course, I mean the lamps which are designed for aquarium. For example, my Arcadia lamp.
I have already put a transparent cover......it is too clear and u cannot see on the photo...
There is a big gap at the tip and tail of the lamp for ventilation. I am now using a 36W 橫流扇 to blow to from the tail and hot air come out for the front gap. It just fit the gap but too big to attach to the lamp. So I'm not attach it on it.
Thanks for your suggestion.
