They are pretty new models and I’ve not seen any proper reviews for them yet.
It looks like there are now a lot of feedback and reviews on the Aliexpress site. The single emitter light looks like it has stepless dimming, 1A charge rate, uses a conventional 16mm star and fits a 20mm tir optic. It doesn’t say the color temp, but it looks like CW. The only thing I don’t like is the headband missing the top strap. Due to the weight of the lights, the top strap is needed, in my opinion.
Oh well, I might buy both since they are so cheap.
