SureFire KE2-A Head Question

[Arch]

Does anyone know if the KE2-A head has always been the standard head for the M600U light?

Yes it is the 500 lumen head

Yes it is the 500 lumen head

Thank you.

The website says it now has 600 lumen. Do you know the model number for this newer head?

The 600 lumen rating is new. The ultra was at 500 with the KE2A and the fury was 600 ( don't know part number) I don't have any new 600 lumen ultras to look at. The fury head was a bit larger and bell shaped- easy to tell apart.

Is it possible that they're just letting the KE2-A run brighter? Or would that be a different head altogether (KE2-B, for instance)?

Reason I ask, is the 500 lumen M600U is supposed to have a 1.75 hour runtime, while the site says 1.5 for the new 600 lumen M600U; Same as the 600 lumen X300U-B and newest iteration of the X300U-A. I'd guess there's not a significant change to the head, just more light for a little less time.

I could, as always, be incorrect on that.
