Oja flat LED ceiling light with IP code IP54 The Oja LED ceiling light has a very flat design. The round LED bulb made of plastic is protected against dust and splash water with IP code IP54 and is not only suitable for the bathroom, but also ideal for use in wellness areas, as the light from the warm white LEDs, which are installed behind the satinised cover, can also be dimmed using an external dimmer. It emits a warm white light colour very homogeneously at an angle of 120°.
