4.2V input ok?
Will this driver be safe for use with one LiION cell, meaning 4.2V input voltage?

No it will not take 4.2V. We have tried 3.2V and it worked fine.

Thanks for the answer, so it will run safely on alkaline, NiMH and LiFePO4, i presume?

Definitely okay wit Alkaline and NiMH. But be careful with LiFePO4, their max voltage after charge is 3.6V. It will likely damage the driver.

I just installed my first one and as I had not read this I ran it on 4.2V driving an XM-L2 on a Noctigon copper base for the past 20 minutes and so far it seems fine except of course it gets hot on High without active cooling. I took a tailcap reading on High and it is drawing almost 2A at 4.2V. When I put a lithium primary AA or NiMh AA in it draws 2.25A and is not as bright. I'll keep using it and see if the 4.2V shortens it's lifespan, in the meantime I'll probably grab some more as I only got 3 of them.
