Over the years I have converted all my 6P and 9P variations to Malkoff LEDs. As a result I was cleaning out a drawer and came upon 5 old bulbs, that all worked when they went into the box in the drawer. A couple P60s, a P61, and a P90 and a P91. Do they have any collector value? I see plenty on Ebay from China for $3-4, so I think not. Some marked Laser Products some Surefire. Can't see ever using them again. Any ideas?
