Wow, tons of great info! I like my freedom micros, but I'd LOVE them if they had a much higher frequency of PWM or plain current control.
Has anyone ever changed the LED in a freedom micro??
Yes, but it is a bit fiddly and you will lose the gold plated LED legs that help prevent corrosion. Any std 5mm LED should fit.
1 You need to lever out the driver unit (start at the end away from the LED),
2 push out the LED (this will take some force, and make sure you are pushing in the correct direction).
IIRC some LEDs push in towards the body, others push out away from the body (all the ones I've done push out away from the body) .
3 bend and cut the legs on the new LED to exactly match the old LED legs, add the little black piece of cylindrical plastic from the old LED (if your PFM has it)
4 replace the LED in the body (check to see you have the right polarity or it won't work)
5 bend the legs up slightly to make it easier to locate them in the holes in the driver unit,
6 then wriggle in the driver unit (this is the fiddly bit). Match up the holes in the driver unit with the LED legs first, then push the opposite end of the driver down afterwards. Make sure the driver is fully seated in the body. Check the LED legs did seat home correctly in the driver (they have a tendency to fold back out).
7 Add batteries, check it is working properly, replace battery cover.
Job done, enjoy your custom PFM.
NB LEDs with low Vf (eg red, yellow, green, NVG) should have 1 x CR2032 battery, LEDs with a higher Vf (eg white, blue) usually need 2 x CR2016 batteries.
