I finally got a Boruit D10 from the official Boruit store on AliExpress: Boruit Official Store.
I received it quickly considering it came from China and was impressed right away. I recall reading all the (mostly) good reviews about Boruit and my expectations were surpassed. It was very bright, the head strap and headlamp attachment was comfortable/secure and adjustable, and the firmware was easy to use. There are enough levels for various tasks and the strobe modes are well hidden. The output appears to be constant, certainly much better than my cheapo Rayovac headlamp where the brightness annoyingly changes based on battery level.
I bought it planning on replacing the LED and lens, but after receiving it, I would’ve been happy as is. The LED was good and bright, but a little too cool white and narrow for what I wanted. I replaced it with a Nichia 319AT D440 70+ CRI 5000K and a 60 degree TIR lens.
Getting the LED out of the headlamp was very difficult due to the thermal adhesive, but eventually it came out.
The Nichia LED seems to be as bright as the original, but with better tint and color resolution. And the 60 degree TIR lens does a great job spreading out the beam with no hotspot. I am very happy with how it turned out. A great headlamp for around $15!
