Nope, the issue with LED's right now is their high cost. But they're rapidly finding a big niche in the industrial and public sectors. The vastly superior lifespan of LED's has lead to an almost wholesale acceptance of their use in things like Traffic Signals, for example. Closer to home, I've gone from early November to now with a single set of 3 AAA batteries in my bicycle headlight and it shows no sign of diminishing, versus the two weeks max I used to get out of the incandescent one. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
