hello we have always used the feather brite lighting for our conures it used to be one light that you used now recently they have done away with the one bulb and are using two bulbs one regular size bulb and a smaller light which is the blue light. dont really know why feather brite has done this maybe to get more money.any way we only have the one type lighting that will accept both bulbs oh bye the way you have to buy an adaptor for the two bulbs. the lamp for these bulbs is quite pricy. we would need to buy 2 more, we recently were looking at the zoo med avian sun compact fluorecent bird lamp which is showing it at 26 watts the feather brite light we use is 6 watts so is this going to be a problem. please help with this what is every one else using for there lighting.just not sure what we need to do thank you for all the help
