Good to hear. We noticed it's showing no stock on the Ali store and Amazon now.

lux-Perpetua should have the full summary of manual changes for the UI, and list of bugs.

Hey Wurkkos. I ordered the HD20 with the battery and it seems to have a flashing red during a 90 minute charge. The charge indicator never turned green. Via the manual it says the battery is critical so I tried swapping it out with another battery and the problem was not resolved. I ordered the light off AliExpress on 11.11.20. Any advice on this issue would be appreciated. Thanks.

During charging the indicator blinks red and switches to constant green when finished. Charging can take up to three or four hours.

My FC11 is a solid red when charging. I looked around and found info regarding the below. I don’t think my battery would still be below 3% after a hour charge. Also the other batteries tested were running well in other flashlights.

3% > Flashing Red
30% > Constant Red > 3%
Constant Green > 30%

That’s the indicator when not charging. While charging it blinks red. Plug it in and wait four hours.

We Tested discharge of HD20 again (batch 1#) different phone and products shows different discharge current, so different equipment will influence the reverse charging current.

Charging by 18W Adapter

HD20 Reverse charge the other HD20 1.67A

HD20 Reverse charge FC11 0.92A

HD20 Revere charge Phone#1 1.08A

*
HD20 Revere charge Phone#2 0.93A*

HD20 Revere charge Phone#3 0.46A

Output voltage is to low. To charge phones at full power you need to keep about 5.2-5.3V .

The meter is placed at the end of the charging cable, I think 4.85-95V is fine.

Workkos, thank you for improving this unique light.

Is it possible to offer more LED options when this light is re-released? I believe several suggestions were made earlier in this thread.

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.
