Have you tried it the other way around, with the Mag bulb in the LED base?<br><br>Not sure if there would be enough there to light the filimant-based bulb, but it might be an idea. <br><br>Also, there would be current differnces, I would think between the Dorcy and the Mag bodies, so there may be changes to the LED- do you know if it come back up to the origional lightl level with new batteries?
