Been shopping and looking at stocking stuffers headlamps for Xmas.
My requirement this time around was usb c on board charging, 18650 or smaller, red light, cri, and floody.
For cheap sofirn and wurkkos H25lr come out on top.
Right now both are on sale.
Sofirn $19.29
Shipping extra.
Couldn’t find any active Sofirn codes.
Wurkkos $15.14
Shipping extra.
WKZHCODE5 for wurkkos brings it down .76c.
$14.38 + tax and shipping.
Quick Google search shows the difference between wurkkos and Sofirn are the led chips they use in the headlamp. Wurkkos uses tn3535 and Sofirn uses lh351d. I know this is opposite of what is stated on the official pages.

His first pictures show the tn3535 chip up-close. Comparing with your pictures #22 and #23 it looks like the Wurkkos has a tn3535 and the Sofirn has an LH351D.
The chip stuff is beyond me so I used AI to ask what the deal was:
For general-purpose, bright floodlighting, the TN3535 edges ahead in output. For tint quality and versatility, the LH351D is the safer choice.
I went for absolute cheapest cost aince I’m gifting these, and went wurkkos.
I’m got 3 so shipping was free for me.
