while it be a solid , durable , and bright light , it have several big disadvantage . for one , the light output drop off way too fast . it have a impressive beam with fresh battery , but after relatively short use , it be too dim to justify the enormous size and weight of the thing . many light , such as the modestly price Surefire g2 pack just as much light output -lrb- or more -rrb- but be easily pocketable and much much lighter . also , the smoooth plastic reflector give it a dirty , spotty beam with noticible dark spot . really , the only thing this light have go for be that it be a pretty indimidating body and have a definite macho appeal . but if you look for serious illumunition look somewhere else .
