Shasha once bubbled...
Let look at some facts (I'm sure most will agree)
1) Most of us people don't dive more than 120 minutes per dive.
But we do per day, and we don't want to be running the battery all the way down to the limit every day of diving.
2) Most of us don't use the focus ability even if they have it.
Have you ever tried a focusable light?
3) Most of us did get to our first million yet.
I'm sure there are allot of people there are professionals that are technical diving all the time that need all the Hi-Tech lights and gear, I'm not saying that everything is bull****.
I'm saying that the difference between the simple and the more advance lights is not all that big.
So the canister is a little smaller, so what is not that big anyway, you will change batteries sometime, right? Once you will it will cost you about 5 times the price of the lead acid ones if not more.
its sort of deciding between two cars with the same engine, one of them has leather seats all the nice things... but they will still run the same on the road, now think that one costs double, will you still buy it ?
Some will most won't.
A 10 watt HID light with a focusable head and NiMH batteries with a 4 hour run time is $665, and replacement batteries (which you won't need for a while) are abou $25. This puts you at roughly twice the cost of the Hawes light.
It's more like deciding between two cars... one which has a 7 gallon fuel tank and one that has a 14 gallon one and you're only allowed to fill it once a day. The first one might be ok if you only do your 40 minute each way commute each day, but you're screwed if you want to go out to dinner that night or pick up your wife for lunch.
