Tonight I had the chance to use my two Wurkkos HD10 headlamps in real world applications, and thought I'd briefly share my experience and impressions as to this headlamp's performance and best uses. (I unexpectedly needed to perform some unscheduled outdoor work, so I decided I'd give these two lights a workout.)
Color temperatures and useful range. I bought both the 6000k and 4000k versions. The two color temperatures made no meaningful difference in application, so choose your favorite and ignore any thought of buyer's remorse. Both versions produce a medium width beam pattern without any shadowing or irregularities. I found the beam pattern to be really useful for distances out to about 20-25 feet (6-8 meters), but beyond that the beam pattern spreads too broadly and the lux becomes too faint to be useful in anything other than an emergency scenario.
Runtimes. With regard to performance against advertised specifications, I found that my two headlamp's runtimes at higher output levels are almost exactly half of the claimed performance levels. Once the cell is depleted the light automatically drops to a low output level, so you have enough light to retrieve one of your backup cells and switch to a fresh one without too much heartburn. (The light uses 14500 li-ion cells exclusively, so no realistic chance of salvaging AA's in the wild. You do carry spare cells, don't you? With this light running at higher output levels you'll need to.)
I also had to perform a few hours of close quarters work, at lower output levels. In my opinion this is where this headlamp really shines. (The pun was unavoidable; just get over it. 😁) At lower output levels the beam pattern for close-in work is excellent, and lower level runtimes can last 6-8 hours, without dimming. As a reading headlamp the HD10 is superb, delivering smooth, even illumination to the page.
So, if you need a lightweight headlamp for close up work, or for use in the house or shop, the HD10 might be a good choice for you. But I recommend that you look elsewhere if your primary application will be in an outdoor environment.
