Auto Dimming Incandescent Bulb works in conjunction with Slow Starting CFL Bulbs

 

This Auto Dimming Incandescent Bulb that Dick Bipes built works in conjunction with Slow Starting CFL Bulbs. When he flips on the lights in his garage that has now been converted into a workshop he gets instant light from the incandescent light bulb while the compact florescents take their time to warm up (many minutes). As the CFL bulbs slowly increase in brightness the circuit that Dick made gradually decreases the brightness on the power hungry incandescent bulb will it eventually goes out completely. A 5 minute timer would have got the job done but it would have been a very abrupt change in lighting intensity.
