01-05-2006 17:22 by dean	no i sent you a link to a 20,000k one
01-05-2006 19:17 by billysfc	No Way, you need a minimum of 10,000k. Also you need to know that your halide light has a filter fitted to filter out harmful UV radiation. Of course all aquarium lights will have one, but a simple floodlight may not due to them being fitted much further away from you or your fish than your aquarium light.
01-05-2006 19:21 by billysfc	Ignore the UV stuff, didn't realise you were just after a bulb. The link that dean sent you in the previous post looks ideal.
01-05-2006 22:26 by tommy	ye im afte a unit aswell .. wot you mean harmful uv radi .. to the fish >?
02-05-2006 18:16 by billysfc	Poss for the fish, but also for you as well, as you're going to be in close proximity to it. Most cheap halide lights are designed as flood lights and are usually attached to the tops of buildings or poles, a long way from you. This was just something I read in a marine magazine one time. You wouldn't want to sit under a sunbed every day would you ?
03-05-2006 08:05 by Alan	Cheap halides use a chreap ballast hence the need for care when buying a halide unit not specifically for aquariums. go on www.reef-eden.co.uk take a look at the new tank set up specifically at the lighting side of things it explains all about uv and halides there.
