Here’s a story that suggests that they can. Like any poorly manufactured or quality controlled product, failures can occur. But with CFL bulbs, there’s additional things that can go wrong over the simple and century long proven incandescent bulb. Read on and see below for some technical details on CFL bulbs. Some “explosive” video also…
Great, just great. Don’t get me wrong, I like the LED bulbs, I have several in my house. But when we get back to basics, a tungsten light bulb doesn’t require a haz-mat squad to dispose of. It’s glass, ceramic, tungsten, some thin steel, and tin solder (if ROHS). CFL bulbs and now LED bulbs…
Also, there’s a poll at the end of this article, asking about what you might be doing for the upcoming ban in California. On January 1st, 2011, just a few days from now, California will begin phasing out the legal sale and purchase of 100-watt incandescent light bulbs. In September of this year, GE closed…
