Hey, from a local surplus-everything store I got a pair of aluminum clamp-lamps with porcelain sockets-- they were rated for 250 watt heat bulbs. The domed and aimable thingies.

Well, I put a fluorescent near-full-spectrum bulb in each and stuck 'em on the treadmill aimed at a user's face, and they're on an outlet strip that also runs the treadmill. One-click health! Wow, I wish I'd known about this option years ago! I guess the bulbs are just now becoming affordable, but wow!
