QUOTE=VWTim]For sh*t's and giggles I took my Mag85 out to the Low light/ night fire course a few months back, let me tell you, you really can have too much light when shooting. The amount of light it put out, on an outdoor range was unbelievable, it lit up my target, the guys next to me's target's, their neighbor's targets. And to top it off the contrast of that much light made my gun in hand all but dissapear and the sights were non-visible. I've since made sure to keep the Mag85 and 74 out of the bedroom nightstand area just in case.
a 60-80 lumen light it much better for use when you need to keep some of your nightvision.[/QUOTE]
VWTIM.
I beg to differ here, with your experience of too much light washing out the sights or just being TOO much.
Once more (after reading your post) I went down to my pitch black basement with my Gov't .45 in stainless steel and tried a few of my MEGA lights, the MAG 951 II with 951 lumens, the EXP 852 (852 lumens) and the Black Bear 678 lumens, I tried a variety of positions, Harries, reverse Harries, Chapman, FBI, I even tried my old (40 years old) black bear position, that is when you place you light in top of you head so the light fall on the sigh and on the target. This position I invented 40 years ago (when no shooting was done with two hands) for the need to see the lousy sights in my pre-war ppk and my WWII Colt .45.
For the life of me I can't see how your sights are going to wash out when you use the light in the Harries, Chapman, Rogers-Surefire or any other position where the light is parallel with the pistol
And even the ones that are not parallel like my black bear or FBI or reverse Harries.
I EVEN TRIED MY 2,000.000 CANDLEPOWER SPOTLIGHT INDEXED ON TOP OF MY HEAD AND ALL THE LIGHT FALLING ON THE SIGHTS AND TARGET, AND I DIDN'T GET ANY WASH OUT EFFECT.
Now this is something so contrary to my experience of many years with lights and shooting, that I have to come up and complaint.
I have built ninety MAG 951's to the members of this and other Police and shooting Forums and for officers of my local precinct, no one have commented on the backlash effect of the light in impairing vision. Many customers write back telling me their experiences with the light in night shooting ranges and none have commented by been blinded by their own light.
If a guy can be affected by too much light, it is me!! I have a fair complexion and blue eyes and can't stand the summer sun for long.
Now, this is a test that don't need any laboratory equipment and that can be done by some of the posters in this thread, I know that Kevlarman have one of my lights, DigMe too, and others can use a 2 million candlepower spotlight to conduct the same test I did.
When people talk about blinding themselves with a powerful light I don't know what they are talking about, so I invite other to do the test and post their findings here.
One more point before closing, if you use any kind of light even a 15 lumens one, your are messing your "night vision" but WHY you need night vision for when you are making the room like day with a MEGA light!!
Best regards to all
