> 3 dayThey bright, easy to install. I do suggest installing it to areas that will get direct sunlight to keep them off during the day. I installed one in a covered area that did not have direct sunlight, but had some light going in. It didnt shut it off. But changed it another location and it was great.

> 3 dayI bought these to put into pole lamps and exterior fixtures. They look beautiful in the fixtures because of the clear glass. The dusk to dawn feature works great. The light looks like an incandescent color to the bulb. I highly recommend and would but them again!

> 3 dayThese have been working well. Turning off when the sun comes out and turning on as night comes. Very happy with this purchase. It’s too soon to see how long they actually last as I just purchased them.

> 3 dayTo begin, I have not tested them yet, however just wanted to comment on info on the box. The estimated yearly energy cost of one bulb is listed as $.84 a year to run, at an energy cost of $.11/kWh. The problem to me with this calculation is that its based off a daily usage of only 3 hours. This may be the standard usage for normal lights however these are dusk to dawn sensor lights designed to be on all through the night. That means the average runtime for the year will be closer to 12 hours a day, making the annual cost to run closer to $3.37 per bulb. Thats 4 times more than the listed annual cost. The other issues I have is with the expected bulb life of 13.7 years. Again, this is calculated based on a bulb life of 15,000 hours at an average use of 3 hours per day, for a bulb that will realistically be used for an average of 12 hours per day. That makes the realistic expected bulb life to be just under 3.5 years. Thats 1/4 the number of years that is listed to be expected from these bulbs. I think given the purpose of these lights and the realistic usage patterns, they couldve done a better job representing both the cost of running the bulbs and the expected bulb life. Just my $.02 **I do want to reiterate that I have yet to actually use the lights and that this was more of an issue I took with the marketing on the box.**

Greater than one weekThese bulbs look like incandescent bulbs yet they are LED. They are brighter than the incandescent bulbs that they replaced. I can leave the light switch on all the time and they turn themselves on and off. Im very happy with them.

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.
