Lightbulbs

• The lights in my bathroom/room are blinking, switching off, or not switching on – why?
• What kind of lightbulb do I need?
• What colors should I use for each room?
• Where can I buy them?
• How did I replace the lightbulbs?

One or both of the lightbulbs probably need to be replaced. Sometimes changing just one is enough – you can check by looking for black stains on the bulbs. To be safe, it’s best to replace both bulbs at the same time.

Use Philips Master PL-C 18W 4P. There are different color variants (e.g. 827 or 840), but the important part is that it has 4 pins (4P).

• Room/Kitchen: 2700K – warm white (incandescent tone)
• Bathroom: 4000K – cool white

You can find them on Amazon or in hardware stores such as OBI.

You can ask Lapic to replace them (he usually charges around 50 €), or you can do it yourself — it’s quite simple:

1. Switch off the lights.
2. Make sure you’re standing securely and can reach the fixture safely.
3. Remove the white cover by pulling it down gently while twisting it a bit.

It may make some metal sounds – that’s normal.

1. Hold the connector with one hand and the base of the bulb with the other.

Pull the bulb horizontally out of the socket (it may require some force).

1. Find the notch on the connector and align it with the one on the new bulb.
2. Push the new bulb in until it clicks into place.
3. Reattach the white cover.

This part can be a bit tricky – push the metal clips gently until everything fits snugly.

Tip: If you replace both bulbs at once, you’ll have even light and won’t need to do it again soon.
