New for 2010, this is the most advanced mil-spec replacement bulb available for 3v POSP and PSO rifle scopes which use D357 batteries. These replacement bulbs were designed at one of the most prestigious engineering bureaus in Russia. The design bureau boasts a Nobel Prize winner who had a hand in the theoretical blueprint for this new diode design. This bulb is white xenon like the light from a car's xenon headlights. This is significantly better for your eyes. Additionally these are much longer lasting as the element length is compact and therefore less open to disturbance during discharge. This is the standard replacement bulb for the red bulbs that come with the POSP and PSO scopes however this is a better bulb than what was issued with your scope. If you are looking for the best bulb on the market, this is it.
This is the bulb that you wantReview by David04.02.2017
Seriously, this bulb is so much clear and non-fatiguing that I'm not sure why the other ones are still made. If you're like me, you've experimented with some (or all) of the other colors already; if you're in that category, you'll probably continue to experiment after this. I'm just saying that the xenon white is probably the best, so try this first.
The best color availableReview by Tristan21.04.2015
I don't know why other brand don't jump on this white color
It is better for me than red or green
A sort of "quiet" color that help me to rest calm behind the scope.
Very good and no fatigue for the eyes.
