have a 2 cell aa mag for 25 year , and decide to get another one and stage it at the other end of the house since power go out frequently in this area . I buy the lead think it would be ` much ' brighter and more powerful . it be not . compare both , with new battery and bulb in the old mag , the LED be only 10 % brighter with its whiter color light . it do project a perfect beam without distortion and illuminate a bit better outside . Quality be up to mag standard . supposedly , the battery last longer , but it will have to save a lot of battery and bulb to justify the cost . if you use it ` very ' frequently , it may be worth it . if not , the old style be just fine . I do prefer the slightly smaller size of the standard non-led mag .
