I bought some fancy-shmancy dusk-to-dawn light bulbs with motion sensors a month or two ago for the fixture outside my front door, but they just weren't working. I was trying to save some electricity by not having them lit all the time, but guess what--coming in and out of the door literally a foot away from the sensor and not having it light up was a serious pain in the tush. Plus, I'm a single female living alone, and I do everything I can to increase my security. Having these bulbs always on when it's dark out is worth it to me. It's always lit up when I come and go at night, which makes dealing with keys and steps and grocery bags and whatever else so much easier and safer. And it turns off during the day when it's not needed without me having to do a thing. No timers, no constantly remembering to flip the switch or cursing because I forgot to turn the light on/off. Easy.

Just received these yesterday and installed in all 3 outdoor porch lights. Worked as described. No timers to worry about. No worrying about turning the porch lights on, or, did I forget to turn them off? Pretty cool invention, light sensitive light bulbs! Got up at 4:30am this morning and tgeyre all on. Went off as dawn approaced just like described. Will update or write another review in a few months to see how they hold up

I have a Lamp Post outside my house. The lamp post has a sensor in it which has failed twice in 10 years. So I decided to try these Dawn to Dusk bulbs for the lamp post. The shade around the light post is made of a heavy opaque plastic. Didn't think these light bulbs would work in the post and wouldn't produce enough light but they did. The light bulb produces a nice warm light but also lights up my walkway. I always use to shut off my lamp post breaker but now only using 7watts of electricity I keep the lamp post light on. No more replacing the lamp post
