It prevents the burning of wires and fuses caused by flickering LED bulbs.
The QF type flasher is an electronic flasher for LED bulbs. LED bulbs are energy-efficient, but when switching from the off state to the on state, a massive current known as "inrush current" flows momentarily, which can be hundreds of times greater than the normal current. Therefore, using a standard flasher designed for incandescent bulbs with LED bulbs can lead to the risk of damage to the flasher (such as fuse overheating, triac failure, or wiring burning). The QF type flasher is designed for LED bulbs and features a protective circuit that significantly suppresses this inrush current. Inrush current of various companies' LED bulbs (according to our research): LED bulb Average current in steady state Inrush current Company A 0.015A 4.80A Company B 0.026A 4.80A Company C 0.036A 6.90A Company D 0.014A 8.48A Shine Ball 0.017A 4.85A *Measurement conditions: Flashed at 6 times per second using a standard flasher for incandescent bulbs. When using our QF type flasher, it is possible to significantly suppress inrush power. For more details, please contact us.

basic information
The QF type flasher is an electronic flasher designed for LED bulbs. LED bulbs are energy-efficient, but when transitioning from the off state to the on state, a massive current known as "inrush current" flows momentarily, which can be several hundred times greater than the normal operating current. Therefore, using a standard flasher designed for incandescent bulbs with LED bulbs can lead to the risk of damage to the flasher (such as fuse overheating, triac failure, or wiring burning). The QF type flasher is equipped with a protective circuit that significantly suppresses this inrush current for LED bulbs. Inrush current of various companies' LED bulbs (according to our research): LED bulb Average current in steady state Inrush current Company A 0.015A 4.80A Company B 0.026A 4.80A Company C 0.036A 6.90A Company D 0.014A 8.48A Shine Ball 0.017A 4.85A *Measurement conditions: Flashing at 6 times per second using a standard flasher for incandescent bulbs. When using our QF type flasher, it is possible to significantly suppress inrush power. For more details, please contact us.
