SureFire M4 Devastator
Available from Tactical
Warehouse
Produced by Surefire
The M4 is one of the largest and brightest flashlights that Surefire
makes. It uses 4 SF123A lithium batteries.
It can produce:
225 lumens of light for 60 minutes with the MN60.
350 lumens of light for 20 minutes with the MN61.
500 lumens for 12 minues total (not continuous) with the N62.
The version I have has the pyrex (glass) lens, it passes more light
than lexan & will not melt if it heats up.
Older versions have a lexan (plastic) lens that can melt if it becomes
too hot. Lexan also scratches easier.
The new "clickie" tailcap switches allow you to press the button for
more conventional on/off
functionality instead of twisting the tailcap. Momentary lighting
is still possible with the new switch.
The M4 is longer than the M3, making it easier to hold or even use
as a weapon.
But it's larger size also makes it harder to carry with you since it
will not fit in your pocket
like the others Surefires I have will.
The M4 Turbohead can be used on the M3, as long as you use the correct
lamp assemblies!
Comparison photos taken against my garage door at 20'
with 2 M4's:
The MN61 has a wider, more diffused hotspot. The MN60 is tighter
but very oval shaped.
The N62 is very tightly focused and perfectly round at 500 lumens!
Comparison photos taken against my garage door at 20'
with the M3 (w/MN11 - 225 lumens) for reference:
Here is a comparison between the M3 (Not M3T) at 225 lumens and the
M4 at 225 lumens.
Notice how oval the the M4s beam is with the MN60.
Here is a comparison between the M3 at 225 lumens & M4 at 350 lumens.
The M4 hotspot is bigger and brighter with this lamp assembly (MN61)
and just a bit oval.
This comparison is between the M3 at 225 lumens & M4 at 500 lumens.
The hotspot is more focused with the N62 and is very intense, but will
eat batteries very fast!
The M4 will only run 2-3 minutes at a time with the N62 before overheating
& is meant
for tactical entry situations requiring short bursts of blinding light.
