While changing lightbulbs in my home office I noted that some new fluorescent bulbs emit a really ugly color light and also are nowhere near their nominal brightness equivalence to incandescent bulbs. Brought to mind an inexpensive device I recall seeing in the U.S. General tool catalog some years back (I think they now are Harbor Freight Tools) which was humorously named "ScrewGE". It was a little disk with some tiny circuitry; must have been a resistor and a clamping circuit. One screwed them onto a light bulb before screwing the assembly into a socket. They were supposed to multiply bulb life many fold by protecting the filament from being worn out by the many surges constant switching on and off expose it to. One could by a pack of them for around the cost of a pack of bulbs so they were a big money and time saver. I had heard they work well but can't seem to find them anywhere now. Has anybody seen these or a similar product?
