thanks for the link, ive never heard of an 18"/18w T5HO fixture. i wonder how hard it would be to find bulbs for it a few years down the road


how bout some LED's :D

hmm, i wonder who may have some :naughty:
 
Check out DIY LED lighting. You could easily build an LED pendant lamp with tight optics that will outperform a 250 metal halide. 24 Cree XPG R5's will provide more than enough PAR to grow anything you want in that tank. You'll get the shimmer effect of a metal halide, none of the associated heat, and the lamp should run for 50k hours minimum before needing replacement.

50k hours is what they are warrentied for but from a purely theoretical standpoint a LED will be able to run for ever and never burn out theres simply nothing to burn out. some LED's made ages ago are starting to dim now (20-30 years later) but modern LED's may be able to last forever we'll just have to wait and see.


I highly suggest going with LED's i am seriously considering some for my 150 gallon tank (off of that same site) LED's are the future of lighting for both the aquarium and everywhere else there a relatively new technology and they already have greatly higher efficiencies than even metal halides (which themselves have slightly higher efficiencies than flourescent lamps) and they will only get more efficient unlike flourescents and halides which are really a dead-end as far an improvement is concerned.
