Osram Parathom G53 LED bulbs have an AR111 shape. This light source is available in 3 colors: extra warm white, warm white and cool white light. If you have a conventional G53 at the moment, we advise you to keep the same color in order to keep the same light effect. In the filters on the right, you can filter on color, but also on replacing wattage. Here, you can give in the wattage usage of your current light source. By doing so, you can choose a light with about the same light output. Also important is the beam angle, choose a small one (24º) for accent lighting or a broad one (40º) for general lighting. After choosing the right Osram Parathom G53 LED bulb, you can replace your conventional light easily, without making any changes to your fixture.
