There have been beam shots of the new Wilma on here, but, as far as I can remember, none of the upgrade. The upgrade isn't quite as bright as the new one (750 lumens vs. 830 lumens) but -- at $150 -- it's quite a bit cheaper than buying a new light if you have the 350 or 420 lumen light.
Here's the 420 lumen Wilma:
And here is the same light head with the upgraded emitters and optics:
I tried to aim them the same, but since I had to remove the light head to make the emitter swap (very easy, btw) it seems to be a little off. I've got bigger versions of the images on my blog.
