I'll get beamshots up when it gets dark. I was going to go 4 LEDs, but the profile was too wide and it was an overkill, as this is already an overkill.

As for details, the two LED is wired in parallel, the driver, switch, and wires fits, just barely. I had to make sure nothing shorts as aluminum is also conductive. Weatherproof using silicone chalking.
