Product Type: Multifunctional Electric Pen Bulb Tail Lamp Power Test Lamp, Light Emitting Diode. It is a type of semiconductor diode that can emit visible light when electrons and holes combine and can convert electrical energy into light energy. It is used as an indicator light in circuits and instruments
Product Material: High-quality LED light bulb with high visibility. After strict testing, the lifespan is long. LED test bulbs are used to indicate circuit signals and the brightness of the light varies with the voltage being tested.
Product features: stable lighting, safer use of low-voltage power supply, about 40% less power consumption than energy-saving lamps, small size, suitable for avariable ring environment
Product capability: High brightness, low heat, stable luminescence, uniform color development, short reaction time, no harmful metals, long service life, 7. High-quality materials, environmentally friendly and durable
Wide test range: 3-36V low-voltage DC In-circuit testing and digital circuit breaker finder are specially designed for checking various automobile circuits and small engine spark testers, such as automobile test lamps, trailer lamp testers, pen testers, fault sockets, fuse connections, etc., and also help test other 3-36V lines and circuits, whether for business or home use. They are a must-have tool and will serve you faithfully for many years.
