Hotaru means firefly in Japanese but these look more like mushrooms to me. Not matter what you think the Hotaru Light looks like, it’s definitely a handy and stylish portable light. The LED lights are cordless and USB rechargeable. There are 3 different brightness levels you can set. The lights can be hung from an included rubber strap, held in your hand, or set down on a table.
Just plop them into the USB base to recharge. They would be pretty cool to use on a patio or out camping, or even just around the house. The lights come in white, yellow, or green for $49 each.
