I bought these for a wall lamp outside the garage and they work well. Beautiful and bright, long-range lighting that doesn't dim in the dark. A few things to note; The manufacturer said they will last for several years, but if you read the product insert, this is based on just 3 hours of use per day. I don't know about you, but in the Northeast, it lasts more than 3 hours a day from dusk to dawn. Even if you put them under the porch or a gray, dreary or rainy day comes, they can also be activated in daylight. Can't comment on energy efficiency or how they hold up in the snow as I've only had them a few weeks, but overall they serve the purpose they were bought for and save me from having to remember to turn off the lights every time. Tomorrow in a hectic hurry at the door. Update: I've had it for several months now, three feet of snow and sub-zero temperatures. They still work just as well and brightly as the day I bought them. As a bonus, there's no discernible difference in the electricity bill, which runs daily from sunset to sunrise.
