I decided to give it a go setting up my camera and taking some comparative Beamshots, and used settings similar to Foy's in his photos.
Camera set to 1/4", 2.8f, WB@5400 and Pattern Metering.
The far tree trunk is the focus of the lights and is 100 ft away, that thing on the bench next to it is a pottery rabbit. The close tree with the overhanging limbs is 20ft away. I'm going to try to do the mouse-over photo trick, and the background image will always be the Manafont XM-L dropin for reference. I shot 12 different lights in about 5 minutes, I resized the original image to 800x600 (no cropping) and sharpened them all exactly the same (night focus issues) so the baseline should be the same for every image.
One other note here, all my lights have smooth reflectors.
I didn't have a clamp to keep the lights focused and steady on the same spot, so some of these you have to pay attention and realize the the focal point is a bit high or left, but I think most of them came out fairly similar in aim. Does make you appreciate the way an XM-L lights up a huge field of view.
First, the Solarforce L2 host with the Manafont 3-mode XM-L, SMO reflector
Next, a Thrunite XM-L single mode P60 in a SkyRay host. Aiming was off to the right on this one, sorry. Mouse-over to see both images
