Flashlight Enthusiast
As I said many times, I never hold my flashlights, because I use them. You cannot often use a light and hold it at the same time, in the real world. And if you use it, the target should be 8-10 hours or more.
I have tried chest lights, belt lights, but found only two types of battery light useful. In addition to the headlamp, there is the wrist light--which can: broaden your periphery vision for walking, backup headlamp when hiking, show texture (in vision area from waist to head level), intensify low areas, help in locating things more quickly than headlamp, and augment headlamp beam intensity and color. Naturally, wristlights aren't for everyone or every task. They work best for walking, or working with one's right hand and holding stuff with left hand.
But your wrist lights need to be much lighter than a headlamp because you are moving your arm about more ferociously than your head. (The hp11 is 180 g w/out batteries, as is many new xml lights).
I know from experience that a 65 g single 18650 light (110 g with cells) works well, weight wise. Just poor runtime. I assume too that if you could keep the total weight under 150 grams (with two liion cells), you should be golden - benefiting from buck efficiency and long runtime.
So, here (in pdf form) is my Non-Tubular, 8 hour (270 lumen flat), 4 K candela, splash proof, comfortable/forgettable, 70 gram wristlight design. I have a ton of unused lights that fail on one specification or another. My focus is on meeting all Specifications, and mistake avoidance. Falling short of any single Specification, or committing a single error, WILL ruin your light.
Beware, form follows function.
