Hi folks
Al's thread about what is good about Surefires and what is not got me thinking about a project which I completed.
The beam of most Surefire lights is what really seems to set them apart from everything else. BUT, the run time is almost never more than a hour. A big disadvantage for long outdoor projects or camping or hiking.
So, I thought-Why not put a surefire assemply in a cheap 6 volt light of some kind...
I finally settled on an old Eveready 8AA double barrel. The rated life of batteries should be about 5600 maH, and with a current draw of about 1000 maH on the R60 bulb, I theoretically should put out for 4 hours with good quality light before dimming.
I hate wasting batteries, so I ran a trial with only 4AA's in one barrel, and it ran for 2 full hours before getting really dim.
The first hour was very close to original whiteness. (I used a new E2 as a comparison)
Even then, the beam was good shapewise and very usable despite being yellower.
The lens assembly has a big and little spring. It turns out the big spring just happens to fit perfectly onto the central lamp holder of the Eveready (pictures below).
The whole thing fits in the flashlight head without modification except pulling out the old reflector, pretty easy).
Once this bulb burns out, I will try the P61 but I think it might be too hot for the plastic assembly to handle. What do you guys think?
The wiring is easy. I can describe it to anyone if interested.
