We have purchased multiple rechargable flashlights and each one of them have died in the process of rarely using them.  Plus, some of the specialty bulbs were very expensive.  When we discovered the Dewalt made a flashlight which uses the same rechargable battery pack which fits my husband's cordless screwdriver, we purchased the Dewalt Flashlight right away.  We use it for multiple tasks.  We have an extra battery anyway so now we can use this flashlight anytime we need one.  Great versatility and great product.
