Top 3 Customer Questions & Concerns �
Can I test high-power LEDs with this device? This tester is optimized for standard through-hole and small SMD LEDs with current draws up to 150mA. For specialized high-wattage COB LEDs, a dedicated high-voltage driver is recommended.
� Will it drain the battery if left on? No, the device only draws power when the red button is actively pressed, ensuring a very long battery life for occasional or frequent testing.
Does it matter which way I plug the LED in? Yes, LEDs are polarized. The tester is marked with "+" and "-" indicators; if the LED doesn't light up in one direction, simply flip it around to verify the correct polarity.
