Sylvania Lynx-D CFL bulbs are also known as energy saving bulbs. These compact but bright light sources are often used in downlights. Due to the 2-pin fitting, these bulbs are only suitable for fixtures with a conventional ballast. If you want to replace your current light source for a Sylvania Lynx-D bulb, you can use your current light source as guidelines for the color, base, wattage, and dim options. If you keep these specifications the same as your current light source, you will remain the same light effect.
