Can you replace the bulbs in the led light when they go out? Are they more exspensive than the light itself
They could be replaced with the right tools and equipment, but a lot to take into consideration. Mostly depending on exactly how the light is configured. If it’s a pcb with a bunch of epistar chips I would probably just toss the whole pcb and see if manufacturer will give you new one or retrofit with better leds.
Also please don’t start multiple topics for the same issue. Pick one and flag any others so I can remove.
