Max Brightness Test Completed 9/4/12
The test was started on April 1st at 09:00 CST
(Not an April Fools joke) and ended on September
4th.
PK-A Venezuela lasted 157 days at
maximum brightness before the battery finally
died.
The runner up is PK01-VS at 153 days. Both of
these are AA powered optics and are two of the
most modern ones that I know of.
I have to say I'm surprised at how long these two
optics lasted at max brightness. My previous
experience was that most of them seemed to
die around 4-5 days but it's pretty evident
the power technology has dramatically improved in
these latest optics.
As I always say I still prefer the collimator
types over the red dots but these two are very
impressive to say the least. Both are rare but I'm
hoping we may see them imported more regularly in
the future.
*My Kobra was not tested due to circuitry issues.
(PMBiker's test from AR15.com is HERE)
PK-A Venezuela - 157 days / 3768 hours
(AA)
PK01-VS - 153 days / 3672 hours (AA)
EKP-1S-03M - 37 days / 900 hours (AA)
PK01-V - 21 days / 500 hours (AAA)
PK-AS - 125 hours (CR357 / DL 1/3N)
PK01-VM - 120 hours (AA)
PK-A original - 96 hours (CR357 / DL 1/3N)
PK01-Vi - 96 hours (CR357 / DL 1/3N)
PK23 - 80 hours (CR357 / DL 1/3N)
The test began Sunday 4/1/2012 at 09:00 AM (CST /
GMT-6), this first run is for MAX brightness
Batteries used are Duracell 3v DL 1/3N Lithium Battery
Model 10315 (CR357 style), Duracell AAA Model MN24000
and Duracell 1.5v AA Model MN1500 (good old copper
tops). The plan will be to check the brightness twice
a day and record the results.
After the max brightness test is complete I'll try to
run it again on about 75% brightness and see where
they end up. The optics are being left in the garage
and subject to daily temperature changes. While I
don't count this as field conditions it's better than
sitting in the house under air conditioning all day.
