Wireless Lighting, Again….
And for the second time this week, we have some ‘wireless lighting’ news. However, this time it is for real, since this solution uses solar power and therefore does not require any electrical wires.
“Just because the sun slips away each night doesn’t mean that you can’t still utilize it. When electrical wires aren’t an option, you can trust solar energy to keep the lights on. Heath/Zenith motion-detecting solar lights can be placed near the dock to illuminate your boat at night and startle any suspicious strangers. Detecting motion up to 60 feet away and operating up to 14 days without recharging from direct sunlight, these lights are energy-efficient, saving an estimated 9 billion kilowatts of energy and minimizing energy pollution.”
