Mine was pretty weak, I couldn't even see it in the house with the lights on. A friend of mine had one as well, and it was way brighter. So, out came the tools. There are 4 rubber plugs on the back, which cover tri-wing screws. The are way down in there, so using a tri-wing bit was out of the question since the socket for it won't fit. A 2mm Allen wrench took them right out.
On the bottom of the driver board is a pot. I plugged the light in with some tape over the light sensor and started turning. I turned to the right until it got dim, and then backed off a bit until it was bright again. I got about double the light out of it.
One thing I noticed was that the positive wire going to the green diode seems to have an Inline resistor with shrink tube over it. I didn't mess with it, or measure it. But, could this be swapped out to increase the brightness more? Or is it likely the board has an overcurrent circuit that would shut it off? How can I turn it up more?
Here's a few pics, you can see the Inline resistor in the first two on a red wire, with black shrink tubing:
