I bought my first one in the 1970’s.Used 4 D cells on a belt pack, cord to the top… high tech and great then. Have a dozen or two of the cheap ones using a single AA bat. They are Ok. Bought a rechargable one a few years back, Great for work and pretty good spotlight and throw.
Just bought this rechargeable one on Amazon for $24 or so. Ribbon of LED. Not nearly as focused or spot for say hunting or seeing a street sign, but I really like for working. Wide pattern good peripheral. High and low, but only about 20% difference. Strobe, dubious value. Side spot light is no help to me. Decent spot and throw, but far enough back it reflects off glasses and is not usable for me. That said, I am going to order a few more and replace all the vehicle and working ones with this style.
