Discussion in this says that it's probably not the best of ideas...

These lights are specifically designed for marine tanks, and that's where they belong, I would say. Sure, it looks "cool", but that's not necessarily good for the fish...

Edit: Fixed wrong link copy'n'pasted...

It's actually just replicating the light spectrum found deeper in the ocean. Deeper in most Amazon Rivers there's going to be very little light, due to the clarity issues. I doubt it would ever be that blue ;). I don't know that it would actually harm the fish, but it definitely makes them look strange, IMO. I know that many people use them in combination with regular lights for their frontosa and other fish that they want to make look more blue.

That link takes us to a Creative Labs discussion Mats ;).

imo it looks very unnatural and way too bright! i have an 18 and 36W (in different tanks) Sera Deep Sea blue light tube. I have this completely covered in aluminium folie except for a few holes with 2-3 cm diameter. This creates a very natural night light and the fish feel very relaxed! its pretty cheap too as all you need is a tube and maybe a powerconverter.

oh..i think for a blue light cuz the xingu/tapajos/tocantins rivers have got a very clear water but they run under the tree,so there isn't light...
i know that look innatural..but,it's dangerous or harmful for my zebras and my QA?

i think what they are trying to say is that it wont harm your fish, but it does not create their natural light spectrum, therefore it will probably look strange for you and for them! and if you want it to look natural then actinic isnt the best bet!

best of luck!
