LED lighting maintenance: cleaning and tips for a long lifespan

In short

• Safe: switch off the power and let the lamp cool down before you clean it.
• Cleaning: use a dry or slightly damp microfibre cloth, without harsh products.
• Heat: make sure the lamp can cool down and do not cover it.
• Check: now and then look at seals, connections and sensors.

Step 1: power off and let it cool

Switch the lamp off and, for fixtures, switch off the whole circuit. Let the lamp cool for a few minutes, because an LED can still be warm.

Step 2: dust it dry

Dust on the lamp or the cover blocks light. Wipe with a dry microfibre cloth or a soft brush. If it is dirty, the cloth may be slightly damp.

Step 3: no harsh products

Do not use abrasives, alcohol or strong cleaners on plastic covers: they turn dull or crack. Never spray directly onto the lamp and do not let water run into the socket or electronics.

Step 4: put it back dry

Let everything dry completely before you switch the power back on.

Provide cooling

Heat is the biggest enemy of LED. Do not cover lamps with insulation unless the manufacturer allows it, and in a small, enclosed fixture choose a lamp with sufficient cooling.

Choose the right type for the room

An ordinary indoor lamp in a wet room fails quickly. Use the right IP rating, see IP rating explained.

Combine suitable lamps and dimmers

An unsuitable dimmer can damage the driver. See Dimmable LED lamps and dimmers. If a lamp flickers or buzzes, read Troubleshooting LED lighting.

Outdoor lighting and floodlights

Remove cobwebs, leaves and dirt from the lens and check the rubber seal and cable entry for cracks. See Installing outdoor lighting and LED floodlights.

LED strips and power supplies

Dust the strip dry. Check that the adhesive tape still holds well and that the power supply has room to ventilate. See LED strips.

Sensors

A dirty or frozen sensor lens responds worse. Wipe it with a dry cloth. See LED lamp with sensor.

Indoor lighting and panels

Dust them a few times a year, especially in the kitchen where grease lingers. A lamp that clearly gives less light or changes colour is due for replacement.
