I know there are a lot of threads about Green Laser Pointers.
Many mention how they tend to fail, or work poorly in cold weather.
I had mine out at about 32 degrees (F) and it just sort of pathetically flickered.
Then the light bulb came on and I came up with a possible fix.
I wondered if insulation could help.
Thought I would start a new thread about a fix - rather than trying to insert this
into many several GLP threads.
I took a few pieces of scrap pipe insulation that I had laying around, and cut
two 1 1/2 inch pieces and used them to insulate the rear battery area of the laser.
I used two pieces - to go onto either side of the mount.
The laser was slightly fatter than the pipe this was intended to insulate, so
I had to cut the insulation lengthwise, and splice another piece into the gap.
Closed with metal ducting tape.
So far so good.
I was able to get an hour session in last night in mid 30 degree temps,
and at the end of the session the laser was still working well.
I don't know how low of a temperature this fix will work for, but the insulation fix
was very helpful to keep my laser going for my initial alignments.
Maybe give it a go and see if it helps you also?
