Superseding the legendary EagleTac M2
series, the new EagleTac M3C4 packs 11
Watt of high output LED power in a com-
pact ashlight body. The M3C4 pushes 800
out-the-front lumen at the turbo mode
(SST-50 and triple XP-G R5 models) and
oers a maximum of 100+ hours regulated
output at the low output mode (15 lumen).
The single-handed operational switch
behind the head allows users to access all
functions easily without compromise.

can explode or cause burns if disas-
sembled, shorted, or exposed to high
temperature. Do not mix with used or
other battery types or install backwards.

the o-rings and threads shown below. (The
operational ring can be removed for clean-
ing by pulling it away from the head).
After prolonged exposure to moisture, the
head and batteries should be removed,
inspected, and dried. The head must be

wise. Remove the retainer ring inside the
head with a pair of tweezers to release the
lens. Do not attempt to clean the reector
surface as it will scratch the reective coat-
