These are regular CFL bulbs. Since you can't find them in stores since the advent of LED lights, ordering them online is pretty much the only option. But they don't seem to last as long as my previous cheap Malwart brands. Some of them have been working for me for over 5 years. 2 of these Sylvanias will blow out smoke after just a few months of use. I cracked open the dead one and tested it, but I didn't see anything explode, so either the glass leaked out of the gas, or a small transformer blew up, or both. I can normally light a pipe with a high voltage Tesla coil, but both were toast. Although this is not uncommon. LED lights are overpriced, they NEVER last as long as they claim, nor do they make very good light in my opinion. I need to buy more of these before they all become obsolete and nowhere to be found.
