Sensor Lights Bulb Dusk to Dawn LED Light Bulbs Smart Lighting Lamp 12W E26/E27 Automatic On/Off, Indoor/Outdoor Yard Porch Patio Garage Garden (12W Cool White 2Pack)

I have just started using these and they seem to be more sensitive that my last bulbs of the same type - different brand. The on/off cycling is working well. The on/off switch on my previous bulbs lasted less than 2 years. The lcd light source may last 10 years, but it seems the on/off switch could be the weak spot Time will tell.

These bulbs work well for us but certainly aren’t as bright as a 100 watt incandescent-more like a 75. (Yes, I compared them to some old incandescent bulbs we have). For our application that’s not a problem but if it is for you buy an imitation 125-150 watt bulb. If they last as long as advertised I’ll consider this a good buy.

Only one worked out of the first set. I asked for exchange and they sent two more. I kept them without returning a perfectly good one so I got 3 for the price of four. Had they all worked I would have given 5 stars. I do wish they were a little brighter.

I purchased these to replace the current out door lights I had which consisted of yellow bug CFL bulbs and separate dusk to dawn sockets. As we all know, the bug lights don't work, and over time the duck to dawn sockets fail. And they did. I wanted a bulb that was both an LED bulb with an integrated duck to dawn feature. These fit the bill perfectly. They are well built, very easy to install and work flawlessly. The price was very reasonable as well. I would reccomend these to anyone that wants to get rid of the seperate duck to dawn socket extension. Here's an additional benefit. For some reason, these lights do not attract nearely as many bugs as the "bug" light di, so that is an added bonus!

I'm certain they work in many circumstances but not mine. My next door neighbor has similar bulbs but his react to dusk prior to mine. That leaves my bulbs still thinking it's daylight and of course don't turn on.

Love these - turn them on and leave them on, even under porch, they shut off at the correct time (enough light, they turn off), even in back with one of those shaded covers...these are great, buying more for backups, i hope they last a long while, that is to be determined...I've noticed many bulbs like this have a lot of cool features, but burn out quicker than one would hope. (keeping fingers crossed)p.s., i have two fairly close (about 1-2 feet on each side of front door, no issues at all)Update: 4/30, purchased - approaching September these work VERY well. I never touch em just turn em in and let them do their work...VERY happy with these.

I'm very happy with this purchase. It arrived on time and as advertised. I placed both lights in my coach light housings on either end of my garage. It provides plenty of light for a dark area and functions as advertised by turning on at dusk and off at dawn. This was the most convenient and efficient way to install a light sensing option that eliminates the need of having to manually activated the lights. Since these were just purchased, I can't attest to the durability or life of the light yet.**Update**12/08/2019, no issues with the lights at all. They have been on all night and every night since purchase.

It's still too early to tell about how well these will last, but so far they've worked as advertised and are super bright.
