Bastard CFL

GE magnetic adapter made in Mexico with a Philips 4100K PL-C Master lamp made in USA. The adapter came with a collar that could be placed around the longer PL-S type (twin tube) lamp and screwed in to keep the lamp from working loose. Indeed, lamps don't fit very securely in this adapter but at least they are easy to get out. It's a noisy thing too....makes a very noticeable buzz particularly when the lamp is cold.
