Title pretty much says it all. I have 2.5 x 2.5 in square post with an id of 2". Right now I'm going to hack up some solar lights that fit inside of the posts. I'll be removing the solar component
s and the small LED bulb and swapping it with a G4 bulb and harness running low voltage. These are all out at the bottom of my driveway by my gate.
This morning the idea of being able to control the color intrigue me so I started hunting for rgbw ZigBee/rgbw bulbs with ZigBee controller that were small enough to fit inside of this 2-in space while being 12 volts. Not coming up with much. Ill leave pictures of the post and the solar light that I'm going to hack up.
I'd like to keep this all low voltage. I can build whatever harness that the bulb base requires as the harnesses are all over eBay.
