While this deal plays out with Autolumination, I decided to try the Malibu 18W 12V incandescent bulbs that deermagnet recommended for comparison. While I was in Home Depot I also found 18W 12V xenon bulbs of the same size / base configuration, so I picked up a set of those to try out as well.

I'll install both sets tonight and try to snap some pics for you guys to compare. Should be interesting...
