- Out of all the lights i have in my collection,
i still carry a Silver Sipik SK68 single AA as my EDC.
For the price its still seems to be the best “bang for buck” little versatile light i have.
I have bee playing with various battery setups, ( extension tubes with 1, 2 & 3 AA eneloops, single 14500s, etc. I noticed however that with one AA Alkaline the amp draw at the tail cap was around 1.8 amps, and when extended with 2 AAs, it dropped to only 0.48 amps,
( while the brightness also increased slightly) but when i added another extension tube to 3 AAs, the draw went back up to around 1.5 amps, though the brightness increased noticably more to close that of a 14500 3.7 volt lithium did.
I decided to do a permanent mod to one of the many SK68’s i have kicking around for use on camping trips for longer run times with the two AA set up.
I cut the barrel off the body of the Sipik , then machined threads in the head of the SK to match that of a 2-AA body from a Ebay “Pailide, GL-037-77B ” 3-dollar torch with a side switch.
The result is a longer, slightly brighter, 2-AA powered SK68 with over a 3 hour run time that is easier to handle with gloves on, instead of the usual 45 minute run time of the single AA powered lights. :bigsmile:
