Dim bulbs. We know them and work with them or around them.
You know the ones I mean. The incandescent bulbs the size of a grain of rice found at the business end of Mini Maglites that cheapen the workhorse flashlights.
Nite Ize (www.niteize.com) has come up with a simple $10 upgrade pack that lets you replace the standard bulb with a cluster of three LEDs. The result is not only a brighter light but one the manufacturer claims will burn four times longer.
The company also makes $10 upgrades for Maglite's C- and D-cell flashlights.
The only downside is that installing Nite Ize voids Maglite's limited lifetime warranty.
That's a small price to pay. Light for all.
