A. The type of LED used may be the answer BUT, there are manufacturers who “over-drive” their LED’s. This results in a very bright light during the first hour (remember this is when you are making your decision to purchase) but with the battery losing power rapidly, the light dims fast. A true comparison can only be made after 1-2 hours of use.
