Arcadia is a brand known to have good UV lamp for birds, and their not the same as for reptiles, there are lamps that you fit into a normal socket and there is the "tube lights/lightsabers
" that you just have to make sure you got a fixture the same size, however if you use the longer tubelights you have to check the frequenzy of your fixture, you will need a high frequency fixture otherwise the lights will flicker for your bird, even if it doesnt for you. as an example if you use a T8 anywhere, that light will flicker for your bird, a T5 depends on the fixture(different kinds of ubelightning). The light that goes into a normal socket is a lowenergy lamp type, it is slightly more expensive than the tubes (atleast here in sweden) however the fixture is cheaper... but not by a great deal, and you have to change the light every 12 month or so even if it still lights up. I think I payed about 22USD for my tube, and it is almost 3feet long, there are shorter and longer ones as well. just checked ebay and their normal lamp there was 80 USD... dont think it did cost that much at the petstore here, but only found 1 seller on ebay on a quick search...
I know there is a brand that were tested in brittain not too long ago called zoomed avian light, but to be honest i havnt heard much about it, neither good nore bad, however I have a hard time seeing it would be harmful, but might not be the best one on the market, anyways they fit in a normal lightbulb socket.
