When comparing CFLs or LEDs, the best way to determine the “brightness” of a bulb is to look for lumens. The higher the lumens, the brighter the bulb.17404_PSO_WebsiteGraphics_LighitngConversion


CFLs and LEDs can work in any room. Some people prefer warm colors for bedrooms and living areas, and cooler tones for kitchens and workspaces.Measured in Kelvins (K), “Light Appearance” describes the color of light the bulb produces. For a warm, yellowish light like traditional bulbs, choose bulbs in the 2,700K – 3,000K range. For natural, bluer light, good for reading, look for bulbs in the 5,000K – 6,500K range.
