Some people have started hoarding old style incandescent bulbs. They are cheap and fragile, but they work well and put out a lot of light, which really is the point of a light bulb to begin with. The reason for hoarding is that some governments have started to ban the old style incandescent bulbs in favor of newer, lower-energy models such as LED and Compact Fluorescent Lightbulbs (CFLs).

For example, in the US, President Bush signed a bill in 2007 that raises energy efficiency requirements of incandescent light bulbs beyond what the can reasonably achieve by 2014, effectively banning them. Other nations such as Australia, Argentina, Canada, and Russia all have similar bans taking effect over the next few years.
