HAHA, 2 reasons for so many. My SL-20XP halogen is much better cutting through some tinted windows. Not always, but on normally stops its also less irritating to the subject because nowadays feelings get hurt when they feel like they are being interrogated despite the fact that my interactions start with a smile and a howdy. I always have brighter light on my belt and on the boomstick. BUT the majority of the time, a fellow partner either only has 1 light, no spare batteries, or forgot to charge theirs. I didn't make rank by not thinking ahead.....
