Initial attempts at harnessing solar power failed after the sun defiantly burned up its harness and went back to ruling the sky. Bask in the brilliance of alternative energy with today's Groupon: for $26, you get an aluminum LED solar address panel, shipping included, from GreenStick Solar (a $55.48 value). Lauded in the Houston Chronicle, GreenStick Solar's house numbers illuminate the path to a more environmentally friendly way of life. Borrowing energy from those with sunny dispositions, this high-efficiency domicile-identification system (normally $49.99, plus $5.49 for shipping) shines with six superbright white LEDs and has space for six 4-inch digits within the solid aluminum base.
This kit comes with three sets of 0–9 numbers, a mounting plate, a number plate, screws, and a rechargeable NiMH AAA battery, and is easy to mount on a garage, mailbox, or trusty steed. More sustainable than an electric porch light, GreenStick Solar's address panel ensures trick-or-treaters, pizza-delivery drivers, and the late-night Publishers Clearing House Prize Patrol all make it safely to your front door after dusk.
