   I've got more important things to think about.   
   But, here goes.   
      
   > Why are some flashlights brighter than others?   
      
   Just like household light bulbs, flashlight bulbs have   
   a rating that indicates their brightness. With house   
   hold bulbs its generally the wattage rating, although   
   we are beginning to wise up and use the lumins rating.   
   With flashlight bulbs its the bulb type (CR-??).  When   
   you buy a flashlight bulb, you can ask for a brighter   
   or dimmer bulb. The above discusion doesn't apply to LEDs.

   Really??

   Depletion of the chemical reactants.

   A poor contact somewhere in the flashlight. Shaking   
   it will restore the contact.  But it can also make it   
   dim too.
