I’ve been using “headlamps” with considerable regularity since the mid-1990’s. My current “fleet” for my family are Coast brand headlamps, all of which are LED lamps and have variable beam focus and rheostatic brightness control. I use multiple models for various tasks - I have multiple HL7’s for lightweight and compact size, plus an HL8 and an HL8R for extreme brightness without committing to the extreme size of larger battery packs or especially to incandescent lamps. I keep an HL7 in each of our vehicles as well for “emergency” use, another in my garage toolbox which typically supplants my corded drop lights for small tasks under the hood, another hanging on the hat rack at the backdoor for expedient access.
