Got my A19 XR-E today and couldn't wait a minute before testing it out. I have not been clear based on the beamshots just how this beam really looked. Based on my data this light
- throws big time compared to other single cell 123 lights
- maintains great output up to about 25 degrees where it drops of sharply.
- is actually one of the more narrow beam angles
This test was done with a RCR123 although output was only slightly less with a primary.
Here's a few runtimes - I show calculated lumens based on the beam profiles. For reference I also show the KL4 hea don the E1L body since that's the only overall competition for lumens output. For the A19 this shows almost a steady/impressive 115 lumens on the RCR123 for about 20 minutes then an abrupt drop. Slightly less output on the CR123 but longer running and no rapid drop.
Pretty decent but I've got to admit I'm a little disappointed in the runtimes as I compare the KL4 head ot the A19 w/XRE. I get about as many lumen minutes from the KL4 as from the XRE albeit at an overall average much lower output.
Overall definitely a quality light with interesting and impressive throw and output over a medium angle beam. But comes with some limitations if you want wide spill beams and/or long run times.
