This is the first cordless outdoor grill light that uses long-lasting LEDs instead of fragile bulbs, for reliable, weather-resistant light without ever having to change a burned out or shattered light bulb. The light attaches to a grill shelf with a heavy-duty 1 mouth spring clamp, and it has a flexible 18 neck adjustable to any angle so you can direct the powerful, bright white light of the four LEDs precisely where needed during after-dark grilling. Unlike standard bulbs, LEDs illuminate food without extra ambient glow that reflects off grill surfaces and obscures the color of steaks, chops, burgers, and ribs, making it more difficult to judge doneness. Each energy-efficient LED lasts 50,000 hours, more than 50 times the life of conventional bulbs, and draws less energy, doubling battery life compared to other cordless lamps without excessive heat. Sturdy stainless steel and ABS plastic construction has been salt-spray tested to ensure rugged outdoor durability. Runs on three AA batteries (included). Wipes clean with a damp cloth. 9 1/2 H x 4 W x 14 1/2 D. (2 lbs.).
