that's the only bulbs we ever run... its nice for the cost savings, but I do it bceause the standard bulbs blow out way too freaking much.
that reminds me of a project I'm working on at work, we are shutting every machine down at 9:00 nightly because people are too lazy to turn their pc's off when they go home. Each PC is looked at as the equivilant of a 60 watt light bulb so the cost savings is huge (when you're talking about 10,000 PC's) I can't wait to see what the stats show.... should be something like a quarter mill savings anually.
