There were several cases of broken tail switch assemblies, one, as I recall was a simple 2-3 foot drop on a linoleum covered wood floor.
cy said:don't think Gladius puts out 80 lumens out the front end. but for the few Gladius I've handled, they put out lumens slightly better than HDS 60's.
they really are two different class lights. Gladius clearly handles better with say gloves. user interface is completely different. my personal preferance is for Gladius, others may differ.
was fortunate enough to witness a live demo of Gladius in action at shot show. they had a dark tent to show disabling effects of strobe. I saw a veteran cop be easily pushed over when hit with strobe of Gladius.
that's not completely true...Handlobraesing said:It's very hard to compare the lumens. Dim sidespills of large area wouldn't look bright, but because of the large area, the lumen allocation can be rather high.
Even if they exactly the same beam pattern, lumens are hard to compare visually, because our eyes have a logarithmic response.

Assuming the same beam pattern, if a test sample is putting out 60% the output relative to reference, it would appear to be 80% as bright as the reference. If it's putting out 25%, it would appear about 50% as bright.
Because of this, they could rate a 25 lumen light as "50 lumens" and when compared against a 100 lumen light having the same beam pattern, it would appear "half as bright" and convince most people its putting out 50 lumens.
In reality, the beam pattern is never quite the same between two sources, so you really need a calibrated integrating sphere equipment to do a lumen comparison.
Would you believe that a 32 watt, not so "bright" four foot fluorescent lamp outputs 2,800 lumens? This is more than a common 2 million CP spot light.

you may not know exact flux output, but in a side by side test. using ceiling beam test, outside throw, room corner etc. it's very easy to tell which light is putting out more flux. temperature of light comes into play, for your eyes may or may not be more sensitive to certain tints.
Handlobraesing said:As for the diffused light testing, that gives you a qualitative way of telling the two apart, but you can't quantify it unless you use a light meter.
