In response to "out of the box" thinking by CPF member, "nukiez", I assembled
some components I already had, in a configuration I had not considered before:
SureFire E2e with P61 high output lamp assembly
L-R: McLux bezel cap, mineral glass lens and 2 ea. #116 O-rings, stock E2e head,
modified P61 LA and E2e power pak.
The P61 shown was freed from its reflector by carefully turning away the Al of the reflector
where it had been glued to the plastic lamp module within. I have since confirmed that by
heating a P61 to 175 F, the glue is soft enough that careful coaxing can free the module
from the Al reflector. Previously, I had found that the addition of a 1/4" washer between
the LA and its mating standoff in the E2e head drops the element in the reflector to a
position that provides a good beam. Without this shim, a black hole is visible in the
center of the beam. I also found that the cathode spring needs to be cut back to allow for
mating with the E2 power pak. The resulting geometry is such that the O-ring on the
power pak doesn't completely go within the head. I suspect this is a result of the shim
required for better focus of the lamp element. The tip of the P61 envelope extends past
the end of the E2e head and would be in interference with the stock lens and bezel cap.
The McLux bezel cap is considerably deeper and with the addition of two O-rings and
a thinner mineral glass lens, a viable assembly has been made.
This light gets warm quickly and it is likely that prolonged use may be thermally
problematical. I leave that to others to determine. Obviously a slightly larger, Deeper
and finned head could take care of these issues. I have no doubt Sure Fire has visited
such a proposal and chosen not to make such a light for reasons best understood by
Above, an E2e with MN03 on the left and the P61 on the right. The lights were held at
the same distance to target (about a foot) the image was adjusted in PhotoShop with the
intensity backed off until the relative light intensity could be seen.
At least with the lamp assembly I have, I have discovered that the original bezel cap CAN
be used. The component build sequence is as follows:
E2e Bezel Cap
Mineral glass lense (.040" thick)
Original flat rubber O-ring from SF
E2e Bezel Body
1/4" washer (.050" thick)
P91 LA with reflector and remaining glue removed.
