I want to decrease the Amperage from 5A to 2.5A. I tried modding a 16mm Convoy 5A 3V Buck Driver by replacing the Shunt Resistor with double the resistance. However the driver becomes now quite warm. Has someone done a similar thing?
Can I just mod it like this? Are there some other options out there? 20mm 3V 3A or 2.5 A would also work.
Reason behind:
I tried to convert a convoy flashlight to a glare free bikelight and made a 3d printed adapter for it.
Project can be found here: https://www.printables.com/model/1587977-glare-free-bike-light-filippa-tir-lens-convoy-s6-m
During field testing I came to the conclusion that I don’t need the full 1200lm but something a little lower. Efficiency and therefore runtime would increase a lot when the Led is run only at half the amperage.

You could use the 12group Ui on one of the groups that only go up to 50%
What about setting it to mode group 9? It limits it to 50%
convoy doesn’t make 16mm drivers, the size is 17. idk which one you’re using but the product page should have a thing about setting modes on it, by turning it on and off really fast 20 times. if it’s a 12 group one you can set it to group 9 and get a 50% maximum output as you want it.
There is 3A driver from Convoy [17mm 7135*8 driver 12groups 3040mA – Convoy flashlight](https://convoylight.com/products/17mm-7135-8-driver-12groups-3040ma?data_from=collection_detail&spm=collection_detail.116036.collection_detail-2134596.15.)
Other than setting to the group that maxes out at 50% you could also put the driver for red led’s but I can’t find one for sale, however you could buy a Convoy with the SST-20 deep red LED and take he driver from it. The driver for red led’s is 2,5A
