Using this Philips LED fridge globe is easy. Just install it in the pilot light socket of your refrigerator. It fits many brands of fridges, but make sure it's not for ovens or microwave ovens. When handling, be gentle as the glass part can break easily. For maintenance, there's not much to do. Just keep it clean. If it stops working, check the socket first to make sure it's properly connected. Since it's equivalent to a 15 - watt incandescent globe, you'll enjoy energy savings. We've been in the business for over 25 years, so trust in the quality of this product.
