I think they would need to decide that at the very beginning of the project, not this far along. You have to design air inlets and outlets to achieve airflow across special sized and shaped heatsinks.
With the current design, about all they could do is strap a little fan on the side of the head and have a special plug for it. That’s not going to be very efficient, though.
They could boost efficiency by enclosing the fins on each side of the fan so all its air is forced out the opposite side. It would not look pretty, though.
Didn’t we have a picture of the cutaway design? I thought we did.
EDIT: I just realized this is the interest list. There is a different thread about the design.
I can’t believe the number of times people on the blf recently are accusing folks of being racist. I don’t get it. An innocent typo of Chinese new year by m4dm4x and instantly accusations of racism is leveled. I have seen similar comments in 4 threads recently. There is plenty of racism to find in our world today, there is no need to concoct a reason to be offended here.
I have no idea, that is what was posted above, not sure why they would say 130mm if it was not the reflector since that would be smaller like you said.
