Sengled Dusk to Dawn Light Bulbs Outdoor, 3000K Soft White, A19 LED Sensor Light Bulbs 10.5 Watt Equivalent, 1200LM, Automatic Photocell Light Bulb for Outdoor Lighting, 4 Pack

For a few years now I have been using Switchmate adapters to turn on/off my porch and driveway lights at night. The company no longer supports this device and they run through batteries like crazy so they have been hit or miss over the years, not to mention look ugly on the switches. I saw these bulbs online which had great reviews and a great price so figured I would give them a shot and am glad I did. These things are great, they all turn on and off at the same time, and at the right times, right before dusk and right at dawn. Not sure about the longevity yet since they are now on every night for several hours but if I had to replace them every 6 months or a year to me it's worth it for the price. Perfect brightness for these areas as well.

I put one in my living room lamp approximately 5 months ago and it is still working. Very bright

I order a pack of 4 dawn to dusk bulbs. They came shipped in a think white plastic bag. Al the bulbs were loose and rattling around. One of the 4 did not work. I had to return for replacements. The second package came shipped the same way but all 4 bulbs worked. Great bulbs and price but poor packaging for shipping.

outdoor security good

Works well as expected. Good life expectancy.

Had a long term trip to take and was worried about a timer being to obvious and the lights coming on at the same time every day. Since the photo cell is built in, these lights come on when needed. It has made the house look occupied during our trips. Very pleased with the durability of these lights so far.

I wish I had known about these Dusk to Dawn light bulbs years ago. My daughter bought some for her outside fixtures and loved them, so I also ordered some. They are one of the best purchases I have ever made. It is great not to ever worry about turning on my porch lights anymore at dark, and the bulbs are very bright. I would recommend these to anyone who leaves on their porch lights each night.

So far one of the four bulbs has been defective. The ambient light sensor initially worked then failed so the light comes on during daylight. Contacted Sengled CS via the links they have provided, provided an additional photo of the bulb showing the model number, I've been waiting a week with absolutely NO response. Very Disappointing. They have a decent warranty which is useless if they don't bother to respond and stand by their warranty. Will likely be returning all of the bulbs.
