Genuine Blocklites put out more light than cheap look-alike units. I've used them for years. They work well and are very bright. Ordinary 9 volt batteries provide many hours of service and are available most everywhere. Put a Lithium battery on and be prepared for years of storage and reliable operation. Insist on the original Blocklites which are identifiable by the Blocklite logo on the light head.
