## Questions & Answers

**Q: do they need electicty?**
A: 120 volts.

**Q: What’s the life expectancy for the bulbs?**
A: I have had 2 fail.  One at 3 months and one at 15 months.  They both failed by going extremely dim. Buyer beware you may have to pay for return shipping.  The first one that failed after 3 months and they gave me a one time exception and shipped me a new bulb without returning old one. The second bulb I would need to return at my cost and they would ship me a replacement. The cost of returning the bulb almost exceeded the cost of buying a new one.  There hassle free warranty is certainly not hassle free.

**Q: Has anyone used this warranty? Any problems?**
A: No problem with the warranty as long as you are willing to pay return shipping.  I have had 2 bulbs fail where they go extremely dim.  The first one failed after 3 months and they gave me a one time exception and shipped me a new bulb without returning old one.  The second bulb I would need to return at my cost and they would ship me a replacement.  The cost of returning the bulb almost exceeded the cost of buying a new one

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great light, dawn to dusk.
*by E***N on January 29, 2026*

These bulbs work as advertised. On at dusk, off at dawn. You never need to think about them. Very good light output. Long life. Bright white. Standard size bulb and socket.

### ⭐⭐⭐⭐⭐ Works great
*by S***M on December 4, 2025*

These bulbs work as they are intended to work. Turns on at dusk and turns off at dawn. Just screw into the light fixture make sure it’s on and that it has to stay on permanently. This light is bright no flickering. Great value for 4.

### ⭐⭐⭐⭐⭐ They're great!
*by J***E on January 8, 2026*

Bought these to help us when we forget to manually turn off the porchlight switches. They work fantastically well. I've only had them a short time, so only time will tell if they have a good life span, but I've been very pleased with them thus far. They're bright and the dusk to dawn feature works nicely. However, I do notice that if you have lights too close together, they can sometimes interfere with one or the other turning on (it'll be too bright to trigger the sensor).
