Many fixtures have recommended bulb sizes and wattages indicated on them. Make sure to adhere to these guidelines to avoid any issues with overheating or lighting deficiencies.Additionally, if you're using smart bulbs, verify their compatibility with your fixture's size and type. Smart bulbs often come in various sizes, so choose one that perfectly fits the designated space without any complications.FAQQ: How do I know what size light bulb to use?A: Check the fixture specifications and consider the bulb type, shape, and wattage.
