This is also a 120 degree spill.
I have taken about 100gigs of footage on these on this trip so far. I thought I would upload a quick clip showing the three modes in action in two different environments.
I've picked these two offcuts from yesterday's dives because I had the light off centre on them, which clearly shows what the light edge looks like. The depths and time of day are listed in the clips. Here you can see the flicker I am noticing on 'medium'. I wonder if a different frame rate of video would impact this (currently shooting 48fps).
For a simple setup like my gopro, price is paramount (for me anyway). To clarify my own little niche, I was after something that would work well in daylight conditions suitable for a cheap hobbyist gopro rig. I wanted something that would cover the entire FOV of a gopro, with no hotspot. I'm not sure comparisons with expensive lights are germane. That said, yesterday another videographer had a Light and Motion SOLA 1200. The light quality was comparable. One big difference of course is that this little Archon light isn't dimmable or anything like that. (EDIT: and there is no spot option with this - only flood). You just twist on and off to cycle through the three modes.
Here's a pic of it on my gopro rig (hero 2):
And here is the test footage:

Here is another tiny clip. The shrimp (and my dive buddy) are about 50cm away. This is also at dusk.

Yesterday I took some footage of a group of flame fileshells doing their bioelectric dances. Absolutely amazing stuff!!! Had to get to the back of a tiny little cavern to see them. I had the light on medium rather than full by accident, and so the footage looks like crud. It's a drawback for sure.
