Frequently Asked Questions
Q: Which bulb base types does this LED light bulb tester support?
A: This multi-interface lamp tester supports E27, B22, E14, GU10, G4, and G9 bulb bases, covering the most common LED lamp formats used in residential and commercial lighting.
Q: Can I test lamps that don't have a standard cap or base?
A: Yes. The dual clamp terminals allow you to connect directly to capless lamps such as ceiling lights, downlights, spotlights, floodlights, and ventilating fans, making this tester highly versatile.
Q: What measurements does this tester display?
A: The tester simultaneously measures voltage, current, power (watts), and power factor, giving you a complete picture of any LED lamp's electrical performance in a single test.
Q: Is the tester safe to use if a lamp short-circuits during testing?
A: Yes. A built-in 5×20mm 3A fuse provides short-circuit and overload protection, automatically cutting the circuit to protect both the tester unit and the lamp under test.
