The power of the tungsten filament bulb determines the test range. For example, for a 200W tungsten filament bulb, the maximum test wattage is le than 100W, which is about half the power of the tungsten filament lamp. b. Explosion-proof bulbs cannot be replaced by LED lamps or energy-saving lamps. If used, the tested lamps will not work normally c. After the explosion-proof lamp is turned on, it will affect the power meter and other data parameters. When accurate data is required, please turn off the explosion-proof lamp function d. When it is impoible to ensure whether the lamp under test is short-circuited, first turn on the explosion-proof function. After the test is normal, you can directly turn off the explosion-proof switch to achieve the maximum wattage test. Package: 1 x Display Lamp Bulb Tester 1 x EU/US Plug
