Screw-In Base Status-Indicating Light Bulbs
Also known as beacon lights and signal lamps, these bulbs emit a high-intensity light so they’re often used in security warning devices and machinery. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
