Using incandescent bulbs to compensate for a slow start cfl

[Dick], like most of us, likes some pretty strong light in his workshop. He’s using CFL flood lamps to save a little energy. Unfortunately, he found that they gradually become brighter instead of that instant light he was accustomed to with his previous incandescent bulbs.

Not wanting to wait around for the lights to reach full power, but still wanting to save electricity, he devised a plan . He would install an incandescent bulb along side the others and fade it out slowly as the others became brighter. He acknowledges that he could have just put a 5 minute timer on it, but the transition would be abrupt and unpleasant. Instead, he built a circuit to get the exact result he wanted.

Just so you don’t miss it, the actual build is available to download at a link toward the bottom of the page.
