I have an UltraFire A10 Q5, and recently it fell from my daughter's hands and stopped working (when I shake it I can hear something being loose inside the module). What are my options? Is there a similar or better drop in (more lumens) that I can install, or I have to throw it away?
erm im guessing a replacement pill would be slim pickens but id first look inside for an easy fix maybe driver or emitter upgrade is in its near future
Decided to open the pill and see what is the damage:
Can anyone identify what driver is this? So thanks to the fall, the diode broke off, tested it with my DMM and it still works, so I am thinking either to solder back the diode, or to replace the 15mm driver with a better one (if there is a better one). Or, replace both the driver and the led maybe with an XML if there is such option. Anyone knows if there is a better 15mm driver, and if so which one? Or one that can drive an XML?
Is this better than the one the light came with? If so, in what sense? Can this drive also an XML, or I stick with the current led (which is fine for this size of light)?
Versus original one - it's regulated when running off a 14500 battery (the original boost driver is DD when Vbatt > Vf)
This not only can drive a XM-L, but will also be better with it! (due to lower Vf of XM-L, brightness will be stabilized for longer).
If you're good at soldering, you can also de-solder one of AMC7135 chips from that driver to extend runtime and make flashlight run cooler, at cost of -30% brightness.
Much appreciate the help Shadowww. 14mm is a standard, so mine must also have a 14mm led base inside, or this applies only to XML's? If mine is 15mm (it's a XRE), can I use a 14mm emitter base inside?
