A type of outdoor lamp that passes electricity through a gas enclosed in a glass tube to produce 40 to 80 lumens per watt of light is known as a fluorescent lamp. Fluorescent lamps are known for their energy efficiency and typically fit the description provided, as they contain gases such as argon and mercury vapor inside a glass tube. While they are more commonly used indoors, they are also suitable for specific outdoor applications.
Gas enclosed in a glass tube is for fluorescent lamp, but it is not the outdoor application. Outdoor application is for metal halide lamp
Agree that answer should be fluorescent lamp. But they do have limited outdoor usage (e.g. tunnels, underpasses and some signs)
