I’ve just stumbled on this year-old thread and realised that the OP is asking pretty much the same question as in my current thread “Powerful hand lamps with high R9”, although his application is different.

I would be very interested in what progress the OP has made in the meantime. Has he managed to find what he was looking for, which lights has he tried (in this regard) and what has his experience been with them?

I also need the long reach and the high R9, although overheating and runtime are less relevant to me.
