Streamlight® Rechargeables…an Innovation That Saves Money and Helps Save Our Environment! Streamlight created the first high-intensity halogen rechargeable light. Unlike a standard D-cell flashlight, you can depend on a Streamlight rechargeable to produce super-bright, cost-efficient light instantly – even in the harshest conditions. And you can count on it to keep on working for years. A Streamlight rechargeable light can be charged up to 1,000 times. Over the average 4-year life of a Streamlight rechargeable, you'll save more than $300 in disposable battery costs. Although we created the rechargeable light to help customers save money, it turned out to be a very environmentally-friendly, "green" idea. Our rechargeables take the place of thousands and thousands of disposable batteries – keeping those batteries out of the waste stream – and helping us meet the latest energy conservation and waste stream initiatives.
