Hennessy Posted October 2, 2011 Report Share Posted October 2, 2011 (edited) What is a high pressure sodium light? What is it good for? Is it true that its almost useless for Aquarium use? Particularly reef? Edited October 2, 2011 by Hennessy Link to comment Share on other sites More sharing options...
DeadFishFloating Posted October 3, 2011 Report Share Posted October 3, 2011 Having tried and had one explode after water splashed on it.......... I can report its rather an impressive explosion. White I suppose depending on how in need of a sudden WAKE UP you are, is either a good thing, or a bad thing. I certainly needed a pant change afterwoods. They suck up the power too, but once they warm up.......... its a dam powerful light. I got mine from a skip bin after a factory was gutted. Seemed like a good idea at the time. but ya BOOOOOOOOOOOOM! So if ya do it dont let the bulb get wet when its on lol Link to comment Share on other sites More sharing options...
__CAV__ Posted October 3, 2011 Report Share Posted October 3, 2011 Sodium lamps are the yellow ones they use for street lighting. Not very good at all for lighting as they produce more of the yellow spectrum which results in yellow light. If you want a light for reef you'll need a lamp which produces more of the blue colour spectrum Hth Cav Link to comment Share on other sites More sharing options...

__CAV__ Posted October 3, 2011 Report Share Posted October 3, 2011 Not much really, If yOu want LEDs for aquariums have a look at the cree ones, Cree is the shit when it comes to LEDs Link to comment Share on other sites More sharing options...
Hennessy Posted October 4, 2011 Author Report Share Posted October 4, 2011 Thanx Cav - I think I might try making them since they're so overpriced.... LED's were invented as a low cost replacement for normal bulb lights, but all of a sudden they cost 10 times more.... Will LED's alone be enough (and the right kind) of light for good coral growth?

__CAV__ Posted October 4, 2011 Report Share Posted October 4, 2011 They will be sufficient if you get the right ones, there's another member on here who uses them in his marine tank, have a look in the marine section and see what you find. As for DIY they arent that hard, a few solder joins and that's pretty much it. I believe A few people have done their own DIY led setups have a search and see what you can find Cav Link to comment Share on other sites More sharing options...
