[Update]Wurkkos dual LEDs 21700 Headlamp design Photos/UI update~

SST-20 4000k 95CRI for the throw LED PLEASE, would take this light to another level IMO, and Sofirn already uses them and should have stock.

I’ve just ordererd a HD20 on aliexpress.

A question : is the firmware upgradable ?

A remark : for the turbo i would like the annouced first, ie both flood + throw instead of only the led used befor going TURBO. I will use it on flood for the main part and may need turbo on throw while lost in the wilderness.

Bonjour yann et bienvenue au BLF!

It is unfortunately nearly impossible to flash/upgrade the internal firmware. Maybe a few people who know how to get access to the MCU and its pin address translation will be able to modify HD20's firmware. But there is no interface available from the outside.

Please check >>> here <<< to find the updated manual which reflects the actual UI implemented in the first batch of HD20.

Veuillez me faire savoir si vous avez des questions.

Now HD20 Green version is available on www.wurkkos.com, check it out.

Are there any coupon codes for this?

Do they take requests for emitter swap like Simon does? I’m pondering about getting one, and the sst20 4000k or another LH351d instead of the XP-L would be a deciding factor for me…
