I'm not arguing pros and cons of regulation at all, I'm just trying to make sure people are clear about facts. A poster above said "it's semi-regulated", and a major web retailer is claiming it contains a microprocessor controlled digital regulation circuit. Well either it does or it doesn't. I have no beef either way, I'd just like the facts to be straight.
Honestly I also have no problem with you liking the light. If you are happy with it then good for you. Don't let me take away from your enjoyment.
What I am arguing is that at the $100+ suggested retail price, this light is seriously overpriced. It claims a brightness on the package of 172 lumens, but does not tell you that this is not the normal output and is only available with a momentary click of the tail cap. What's worse is that the "try me" on the package does this momentary click. That's badly misleading.
If the light just has resistors in the tailcap and has no electronic regulation circuit then it isn't worth $100 (or even $70). It doesn't matter that it seems to do OK on NiMH, it is too much money for what you get.
If it were priced at $35 (or maybe even $50) I would be happy to buy it. But at $72 or more, I won't be. I have nothing against how the light performs, it is just too expensive for what it is. Manufacturers should not dress up basic engineering with cute buzzwords and then hike up the price tag in a cynical marketing exercise.
