## 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

### ⭐⭐⭐⭐⭐ Reliable, Nice light, soft yet bright enough to deter.
*by W***L on December 2, 2025*

Works like a charm! Reliable. Always turns on and off the light outside my front and back door. Husband thinks it’s great too. Very pleased.

### ⭐⭐⭐⭐⭐ 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).
