If using in a 3 cell flashlight, don't bother
on November 14, 2012
This really shouldn't be listed as a 4.5 to 6 volt bulb. It really doesn't work well on 4.5 volts (or 3 cells). On 3 D battery flashlights, the output is marginal at best and no where near the rated output. If you put it on 6 volts, the output is significantly brighter (not great mind you, but honestly it is only rated at 40 lumens to begin with). So to achieve the rated 40 lumens, you have to have it in a 4 battery flashlight. Thus the item seems a bit misrepresented to me. For 3 cell flashlights, there are far better LED conversions out there (cost a few bucks more, but well worth the money).
