The Hidden Struggle of Home Lighting
Most homeowners don’t realize how much their lighting choices affect daily life until problems emerge. The wrong bulb flickers in ceiling fans, creating distracting strobe effects. Decorative fixtures lose their charm with harsh, clinical lighting. Vibrations from slamming doors or active children prematurely kill standard bulbs. Many resort to expensive “designer” bulbs or compromise with unflattering LED alternatives – sacrificing either their wallet or the warm ambiance they crave.
