I often forget to turn off my patio light as it uses electricity during the day. In my search for a Dusk Till Dawn photo sensor, I came across several brands of LED lights with standalone sensors. My experiences with LED bulbs have been mixed. Lamps often lasted a month with a 50 billion hour guarantee. Although it was guaranteed, it was impossible to figure out how to use that "guarantee". So I just went with the cheaper option, Minger bulbs, for this order. I have never heard of them. I figured it was just another seller of cheap Chinese made junk from a source with no quality control. However, I was very surprised when a package arrived with an order for three bulbs. Each bulb was packaged in a cardboard box rather than the flimsy paper boxes that most bulbs come in, and each box included a card with full contact information for Minger customer service. The? I have never bought a lightbulb with customer service information on it. The thing is, I'm pretty sure there is a way to contact the seller for a replacement if some or all of them don't last as long as promised. Try it with a GE lightbulb!
