I’m just wondering if there was a functional problem that made them choose to do that, or if they just randomly pulled that idea out of the anus and thought it was a good plan.
I exactly want to use high current capable buck driver in this light, so yeah this kind of driver cannot be found in 17mm size yet AFAIK. The LD-4B (or LD-40) is too weak for our hot-rod application.
Anyway it is just a suggestion from me. I hope you can help me to ask them about this change but if it really can’t be made it is still fine. I understand that GB can never please everybody.
