If you have had issues with LED bulbs burning out, it could be one of a number of reasons. You may be trying to dim non dimmable LED bulbs (not all LED bulbs are dimmable), or you could be using dimmable LED bulbs with a non-LED compatible dimmer. In this case, switch to using a trailing edge dimmer switch. If you find yourself burning through multiple LED bulbs quickly, the mains in your house might be too high. In UK homes, the electricity should fluctuate around 230V at 50 Hz. If this is the problem, you should contact an electrician to test, and your electrical provider to correct the issue.LEDs can sometimes overheat if used with a fixture that isn't LED compatible. This can cause them to burn out. If none of these reasons are the cause, then you could have used a bad batch of LED bulbs. In which case, contact the manufacturer.
