Thanks for the replies and suggestions.
I consider my current light to be an EDC and it's not "small". :X
Just meant that I didn't want one of those huge mag light's that weight 10lbs. I don't need it to pull my pants down when it's clipped on my pocket.
I'm going to take EDC out of my title.
Longest I've ever left my current light on was 10min and max temp it went up to was 88.9F MAX of the entire light, so something around that size would be ideal.
My Current Light:
Length: 160mm
Diameter: 42mm(Bezel/Head) - 26mm(body)
Looking for a host that can put out the max brightness of the XM-L2 for 10minutes+ and not get overly hot, with a pocket clip.
