Greater than one weekWorks as described all you need to do is have ur light switch on the ON position at all times. Once it gets dark enough the light turns on automatically once the sun starts to rise and it’s bright outside it automatically turns off. I like this more than smart bulbs to be honest their brighter and just better looking. But the bulbs are huge compared to a standard light bulb!

06-06-2025I needed a decorative, dawn-dusk bulb for the clear fixture on my post light. These fit the bill. So far, so good.

02-06-2025I like the fact that l no longer need to turn the lights on at night and off in the morning. The light sensor does that for you .

> 3 dayMy husband and I are bad about remembering to turn the outside lights on and off every day, so wed either forget to turn them on at all, or would forget to turn them off. I love the look of the bulbs and was so happy to run across these! They go in just like regular bulbs. They come on at dusk and turn off at dawn. Now we can just leave the lights on and the bulbs will handle the on/off part for us. Great especially since we like to travel and worry about leaving lights on 24/7. Worth the price!

> 3 dayWhen installing these bulbs two of the ten did not work correctly. I contacted manufacturer directly and they sent two replacement bulbs immediately. Their communication was excellent. The bulbs themselves fit great in our new outdoor lights and promptly turn on at dusk and off at first light every day. So nice!

> 3 dayReceived lights in a timely manner. They look great - like the picture. Only one worked. The other one would come on and go off. It has been over a week and the one continues to come on at dusk and go off at dawn.

> 3 dayUsed 6 in various areas outside my home. Work well. Two broke of the six ordered so I contacted the seller and I was sent a 4 pack within a couple days. They work well even inside my lantern enclosures with seeded glass. All 6, no matter where on my property turn on and off right around the same time.

Where do I use an ST64 light bulb?
These glass bulbs with their high tech LED filament inside provide a retro styling to any space. This ST64 LED Filament Bulb with Dusk to Dawn is wet rated and designed for exterior use. Add it to lanterns or wall sconces on your exterior walls or porch, to pendant fixtures in your outside dining areas, or any retro light fixtures like gooseneck barn lights. They may also be suitable for string lights with an E26 base.
What is a Dusk to Dawn Sensor?
Sunco Dusk to Dawn lights improve your outdoor security and provide bright light with the convenience of automated night lighting. Our D2D bulbs turn on when the sun sets and automatically turn off when light is detected. Just switch it on to power the LED and let the included sensor do all the work. No timer is needed. Automated lighting helps create the illusion your house is occupied, even when it is not. These clever lights activate on their own so you can run a last minute errand after work and still have exterior lights on when you return after dark.
Why does my Dusk to Dawn light flash on/off?
Sometimes reflective surfaces can fool a Dusk to Dawn sensor into thinking there is sufficient light available, so the light turns itself off. It then registers no light detected and turns itself back on. This continues in a loop of off/on/off/on so that the light can appear to be strobing or flashing.
Consider these potential solutions: 1. Point lights away from one another so their beams to do not strike the D2D sensor in nearby light fixtures, 2. Use a dual bulb fixture with bulbs pointing in different directions, 3. Move a light fixture above a garage window or away from a doorway window will reduce the chances a reflective surface might mimic a light source and fool the D2D sensor.
Do I need a timer to set the Dusk to Dawn feature?
No, there is no timer needed for Dusk to Dawn bulbs. Flip on the light switch and the included Dusk to Dawn Sensor does all the work for you. It turns on when light is absent and off again when light is detected.
What does Wet Rated mean & why is it important?
The terms Wet Rated in our product descriptions and technical specifications refer to moisture ratings. Safety should be the main focus when you choose wet rated light bulbs. Since water is a conductor you want to eliminate accidental electrocution to protect the people who install and use light fixtures, including your family, visitors, and clients. Using Wet Rated light bulbs is appropriate for wet areas where dripping water, rain, or other liquid that could flow or splash against your light fixture or LED bulb. Sunco indicates the moisture rating in our technical specifications so you know our products meet set standards. Wet areas are not just exterior locations (though you can only use Dusk to Dawn bulbs outside). Use Wet Rated light bulbs in kitchens and bathrooms in select safety zones. Established safety zones identify areas that might be susceptible to exposure to water, such as near a bathtub or sink faucet.
What are warm lights or cool lights? What about color temperature?
Color temperatures are measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. This measurement allows you to describe the quality of a light. Commercial and residential lighting applications typically use from 2000K to 6500K color temperatures. Lower color temperatures offer a warmer look. They are more amber, yellow, or a warm white. High color temperatures offer a cooler look. They range from white to blue to blueish silver. Light can help create a mood or define room ambiance.
