Does it stay in programming mode even after disconnecting the power?
Haven’t tried it so will do.
No, that is now you enter/exit programming mode.
Yes, it will still be in configuration mode after turning it off/disconnecting power.
Read the data sheet linked above ^ and the added side notes (extremely helpful side notes).
Only way to exit is to click out, or leave the light on/idle for 30 seconds,
Thanks guys that did the trick.
Would’ve never thought it was in programming mode. Haven’t touched that light in maybe a year.
Even after reading, although it was a quick read, the datasheet I wouldn’t have thought about it.
You can enable Configuration menu password, this will prevent unwanted entering into config. menu after 10+ half-clikcs (with configuration menu password enabled, only possible way to enter into config. menu is to enter 1865 password via clicks).
I recently put together a light with LD-4B , 3up Mosled and one of these tail switches…
The light is acting only in single mode and I can’t seem to get into programming. Any suggestions on what i’ve done wrong?
Is led4power webshop going be online sometime ?
Does that LD-B4 has bleeder installed? Check driver with normal clicky switch to see if it works ok.
Yes, but I cannot get the exact date, I expect to have clearance sale in about 10-15days.
Yes, I tried that. Still same problem
Does LD-B4 have bleeder installed (original)?
I’ll need to desolder the wiring to double check what’s on the board but i assume it’s all stock standard as I didn’t do anything to it myself
Bleeder is optional during ordering process, so maybe you have driver without bleeder.
Shouldn’t I get normal operation with a regular switch then? It’s still single mode with a regular switch
Could you measure current, is that single mode 100% or other? Did you maybe enable single mode in config. menu?
Can driver enter into config. mode after 10+ clicks?
If not, it seems like some some off-time memory components are damaged and driver can't switch to next mode.
With regular switch i cannot enter config menu. I tried to measure the current and got a max reading of about 4 amps.
In that case it seems some of off-time memory components are damaged (3 o'clock, capacitor,resistor,diode).
Doh! Must be my shitty soldering skills… again 
Worth checking that there’s no solder linking the via for the negative LED cable with the outer ring.
(Also, not sure what would happen if the positive via is connected to the centre spring pad. )
Neven,
I hope you are doing well with the earthquake and all. Any update on when the shop might open? Thanks.
