Why do my LED lights flicker?
If your florescents flicker every now and again, it’s probably not a huge concern. For LED bulbs, the most common cause of flickering relates to dimmer switches. These dimmers are manufactured to handle higher electrical loads that don’t always coincide with the lower voltages of LEDs.
How to stop strobe light from flickering?
It’s all about the connections: A loose one between the on/off switch on your lamp or light fixture and the lightbulb itself could be the culprit. Wiggle the switch gently to see if it evokes a flicker; if yes, simply replace it to stop the strobe light effect. The issue could also arise from a loose connection between the plug and the outlet.

What is a TCO switch?
A TCO is a thermally regulated switch that is wired into the electricity supply line linking to the bulb socket in the fixture. It features a metallic linkage that expands with a temperature increase around it. If the surrounding space gets too hot, the TCO expands in such a high degree that power supply is interrupted triggering the lights to go out. The TCO around the fixture then starts to cool off, and the coil reconnects the electricity. The bulb subsequently lights again, and the process of TCO activation begins again leading to the frequent flickering of light bulbs.

If the wires are not secured and tightened correctly, the loose connection between them will cause recessed lights to flicker.
Why do LED lights flicker?
Dimmer switches are common culprits with the flicker of LED bulbs. A common cause for this scenario is a lack of resistance in the lamp which makes the dimmer curve function less-effectively.
