While I'm supportive of innovation, the kickstarter item is twice as-expensive as my system, and it's only for one door. My system is for two doors, so it's 1/4 the price of the kickstarter system, and you can easily do this in an afternoon. Want the lights to come-on when the door goes-up? Simply plug the lamps into a remote-controlled garage door opener light. Look at the wall between the OH doors, you'll see a remote-controlled luminaire, it uses two bulbs. Replace one bulb with an edison-base screw-in fixture to a single two-prong outlet adapter, probably $4 at your local Ace Hardware. You open the door, the lights go-on.
I've made brackets using 1 x 4's and Simpson Strong Tie butterflies to suspend 4 LED 4 ft luminaires beneath the open garage doors, I'm very happy w/the setup. The 4 ft. LED's are the Costco luminaires, everything cost-about $100.
I also used the wedge-shaped space above the doors for storage of light, but bulky items like Christmas decorations and empty bins.
The pop-riveted together bracket is one of the two hangers for the luminaire between the garage door tracks. I was gifted with a florescent shop 2-bulb light, and this was a good place to use it. The hanger fastens to a 2 x wood piece screwed-between the adjoining door tracks. The metal bracket pop-riveted to the butterfly is the horizontal piece that the shroud of the florescent luminaire is bolted-to.
