Dusk to Dawn Light Bulb, Sensor LED Bulbs Smart Lights Bulb 5W A19 Automatic On/Off, Indoor/Outdoor Lighting Lamp for Porch Garage Driveway Yard Hallway(E26,Soft White,2-Pack)

These 40 watt bulbs worked very well and the brightness is perfect

Like the bulbs a lot. Don't have to worry about people coming to my house in the dark. Turn off at dawn.

The dusk to dawn function works perfectly, even when used inside a frosted plastic light fixture. The 2700k warm white is just what I need. It gives light but not too bright for my pathway. Easy to install on existing light fixtures. Hope it will last.

These 40 watt equivalent bulbs work as described. The built in light sensor turn the bulb on when it starts to get dark, and turn it off when its getting light. Be aware that placing in darker, shaded locations, or under overhangs, may affect the on/off times. That's just common sense and to be expected. Light output is as expected from a 40 watt equivalent bulb. The 2700k color temperature is the same as the soft yellowish light emitted by an old school incandescent bulb, none of that garish, retina frying blue/white that looks so repulsive in most settings. Put these in your outdoor lights, leave the switches turned on, and never again worry about coming home to a dark porch or stairs because you forgot to turn on the lights before you left. Energy efficient LED bulbs use less electricity so they'll save you money, and they typically last for years longer than regular bulbs.

So far light bulbs appear to be working great. Color is good and perfect for our outdoor light at front door. On a dusk and off a daylight in the morning, keeping the front door nicely lit and also some security. Will update the review in a year to see if the bulb is lasting a long time.

Great bulbs! Does just what it says.

I was so happy to find these bulbs. They work exactly as described: when it gets dark outside, whether by nightfall or storm clouds, the light comes ON. I thought I was going to have to hire an electrician to install a fixture with a sensor but these work in my existing light fixtures. I put one bulb in the fixture outside the front door, and I put another one in the fixture on the patio. No more coming home to a dark entry! I highly recommend this product!

Good deal on hard to find bulbs
