A 9W germicidal lamp in a modern compact fluorescent lamp form factor Glow of a germicidal lamp excited by a high voltage probe. Close-up of the electrodes and the safety warning. A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light.
Germicidal lamps are simple low-pressure mercury vapor discharges in a fused quartz envelope. Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma. Typically, such lamps use a noble gas (argon, neon, krypton, and xenon) or a mixture of these gases.
Lamp age or fouling or outages (reduction in UV intensity) Bulbs require periodic cleaning and replacement to ensure effectiveness. The lifetime of germicidal UV bulbs varies depending on design. Also, the material that the bulb is made of can absorb some of the germicidal rays. Lamp cooling under airflow can also lower UV output.
The lamp's electrodes are typically made of coiled tungsten and are coated with a mixture of barium, strontium and calcium oxides to improve thermionic emission. A germicidal lamp uses a low-pressure mercury-vapor glow discharge identical to that in a fluorescent lamp, but the uncoated fused quartz envelope allows ultraviolet radiation to transmit.
[5] [6] On the other hand, Creative mode equips the player with an infinite amount of every block and items on the game. The character could fly and could not die or experience an injury while playing in this mode. [1] In Survival mode, the player begins with fish in their inventory. The player is also able to go back to where they slept, as well.

Survival mode has been compared to the gameplay of classic arcade games, where players face off against increasingly stronger waves of enemies. [3] This mode was intended to give the game a definite and sometimes sudden ending, so that other players could then play the arcade game as well.
