I really like this light. I brought this one to replace the first light I have had for a several years.  The first one was out of warranty and the flex broke near the base of the base of the light. It still worked, but you couldn't hold it in position.  Hoping they have improved the design. You can bend this to just about position to get light on something and free both hands to work on it. Uses the standard Dewalt 18v rechargeable batteries. Has a spot in the light to carry a spare blub, it's near the blub, remove the cover like you are going to replace the blub and you will see the small hole to drop a blub in. My first one came if a spare, now they don't. The blub lasts a long time, but if you don't want to be without light drop in a spare just in case. I own three different Dewalt 18v lights and if I need to work and free both hands this is the one I pick off the shelf. I gave it 4 of 5 stars because of the concern it too may break the flex again and need replaced. Amazon's price was great, cheaper to buy the new light than the part to repair the old one.
