"night light" bulbs

[Deminon]

does anyone know if there are bulbs for fish tanks that produce a bluish color light that resembles night? I have a few nocturnal fish and i figure if i had a light that made the tank look nightish my fish would come out more.

Blue LEDS are what is normally used.

You can probably get them from a shop that sells computer modding gadgets, although you will probably have to get a seperate 12v power supply to run them.

They are small, dont use much power, put out a suitable amount of light for a 'moonlight' and should last for years.

Anyone know if you can get the Blue LED lights at radioshack? Or Staples maybe?

I'm looking for some cheap ones, I dont want to have to run a seperate power supply because I suck at rigging electronics.
