How is it that they aren't in the same class? Both are single CR123 cell multi level LED lights designed to be carried as a back up light. :thinking: Just because one costs more than the other doesn't mean they aren't comparable.I'd have to agree with Yaesumofo -- not really sure why you have to decide between a $110 E1B vs a $58 IncenDio. They really are not in the same class feature wise nor price wise.
You will recoup more of your investment with the Surefire so you can try a different light. Just MHO
BTW, the IncenDio can use RCR123 cells and is even brighter when doing so. About 130 lumens out the front on regular primary 123's and maybe even 160 lumens on rechargeables (the E1B only claims 80 lumens on high). The claimed IncenDio runtime using the high setting is over 2 hours vs only 1.3 hours for the E1B.
