Frequently Asked Questions

Q: Does the LDHLM dusk to dawn bulb work with standard E27 lamp sockets?

A: Yes! The LDHLM dusk to dawn LED bulb uses a standard E27 screw base, making it compatible with the vast majority of household and outdoor light fixtures. Simply screw it in and leave the wall switch in the ON position — the built-in photosensor handles the rest automatically.

Q: What voltage does this dusk to dawn sensor bulb support?

A: This bulb supports a wide input voltage range of AC 85V–265V, covering both 110V (North America) and 220–240V (Europe, UK, Australia) systems. It's a truly universal bulb suitable for use worldwide.

Q: Will the bulb turn on during the day if I'm in a dark room or closet?

A: The photosensor detects ambient light levels. If the sensor is in a location where light levels consistently drop below 15 LUX — such as a very dark enclosed space — it may activate. For best results, ensure the sensor area of the bulb has access to natural ambient light so it can accurately detect day and night cycles.

Q: How long will this LED sensor bulb last?

A: The LDHLM dusk to dawn LED bulb is rated for over 30,000 hours of use. Even running every night for approximately 12 hours, that's roughly 6–7 years of reliable, low-maintenance operation.
