If you put a GU10 LED inside a traditional fire can downlight housing and have it on for long periods per day (3 hours+), youll most likely discover they dont last for very many years and youll be forever having to replace the LED.
Do LED lights ever need to be replaced?
Most LED bulbs boast a lifespan of up to 50,000 hours, which means that you may not have to splash out on LED replacement bulbs for up to 10 years after your original purchase. Incandescent bulbs and halogen bulbs will probably only last for 1000 - 2000 hours, compared to up to 100,000 hours for dimmable LEDs.
Why do LED downlights flicker?
The most common cause of flickering LED lights is a poorly matched LED power supply, otherwise known as a LED driver. As a general rule of thumb LED downlights most commonly use constant current drivers and LED strips constant voltage.
