When selecting fixtures for your bathroom: CRI (Color Rendering Index), and color temperature. CRI, choose a fixture with a high CRI (90+ is preferred). Incandescent and halogen light sources always have the best CRI – 100 – meaning they most accurately render colors. If you wish to use an energy-efficient LED or fluorescent light source, ensure your selection has a CRI or at least 90. For temp try selecting fixtures with a warm color temperature (2700K – 3000K).
