With all of the toy options out there these days, it’s hard to know which ones to pick for your child-you want something that’s going to keep Junior safe and entertained, while maintaining your sanity and checking account. And with the electronic toy industry growing by leaps and bounds, it’s becoming even more difficult to find toys that are both wallet and planet friendly. But luckily, LEDs have changed game for parents all around the world. Now, kids can enjoy light-up and interactive sound technology without the high-energy costs of electronic toys.

For instance, See Toys by Zen Designs are toys that light up and make sounds and are powered completely by rechargeable batteries that get re-juiced every time the child plays with the toy. The product line includes wind-up or crank-powered toy fireflies, dolphins, sharks and tigers, with colorful LED eyes realistic sound capabilities. The interactive nature of See Toys stimulates kids’ minds and encourages them to use their imagination. And, LED toys are safer than traditional electronic toys too! Because the battery is rechargeable, you will never have to remove it or replace it, which eliminates the danger of swallowing or otherwise ingesting toxic substances for your kids, and the cost of buying more batteries for you! Every year, thousands of kids swallow batteries, most of which contain potentially toxic metals like mercury, cadmium, lithium, and copper. Health risks associated with mercury include kidney damage and genetic, neurological, and psychological disorders. Cadmium is a confirmed human carcinogen and is poisonous when ingested or inhaled. Even if batteries are not swallowed, they still must be disposed of in a proper way, through a toxic substance recycling program. Purchasing toys that employ energy efficient, lightweight LEDs removes such hassles from your life, and keep your kids out of harm’s way.
