I was happy today!
I received some drivers from Lexel, I would finally be able to do something to break the quarantine boredom.
And so I did.
I picked my Bliztwolf BW-ET1 (e-switch, 1 or 2 AA cells) that i wanted to mode for a while. It was a light I reviewed a while ago, I took the driver out and never used it again.
I wanted to mod it to use 2 x 14500 Li-Ion cells and Anduril firmware.
So, today I received the 2S 15mm driver and took my chance.
I forgot to ask Lexel to add the switch wires, and had to add them. Small pads, but no issues.
Then I needed to do one of the trickiest parts for me, something like “piggybacking” the light, using the original driver “contact board”, that has a specific size and shape.
I had to remove the spring from the driver (I also forgot to ask to not include it ) and put the + wire back in place.
I also had soldered 2 wires onto it the original board, that would be soldered then to the driver.
After this I add to solder the e-switch and I tested the XHP50.2 (soldered onto a aluminum PCB that was from an old XML2 led ) I got from a BLF member some weeks ago.
Even without soldering it, it was working , so I consolidated the work.
To avoid contacts/shorts between the reflector and the wires’ solder, I added some tape on the back of it.
With everything mounted, I turned the light ON and…it only worked well for some seconds :zipper_mouth_face:
After powering it in Turbo, the light started to turn blue.
I immediately shut it OFF and looked to the led… It turned it ON again and it only aggravated the situation
So, what did I do wrong here?
Bad led reflowing?
Too thin PCB?
Any help concerning this is helpful… Thanks in advance!
I have other mods planned with this type of Led and 2S 15mm drivers (14500 Li-Ion), so I am now thinking to order other XHP50.2 from Simon eventually.
