A mercury -vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light. Free Delivery on Eligible Orders! The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. The mercury vapor lamp is a high intensity discharge lamp.
This is different from fluorescents which use the mercury vapor arc to create a weaker light. In case of fluorescent lamp the mercury vapour pressure is maintained at lower level such that of the total input energy gets converted into 253. Again transition of the electrons requires least amount of input energy from a colliding electron. As pressure increases the chance of multiple collisions gets increased. A mercury vapour lamp has at its centre a small quartz arc tube filled with argon gas under high pressure.
This contains a tiny drop of mercury and tungsten electrodes. When electricity passes through the arc tube the mercury is vapourised and emits radiation - heat, light and a great amount of ultraviolet light.

We have a large array of reptile lighting products, including light bulbs, daylight bulbs, Ultra Violet Tubes, Compact UVb bulbs, Mercury vapour bulbs, metal halide.

Mercury -vapor lamps are subdivided into low-pressure, high-pressure, and superhigh-pressure lamps according to the operating pressure.
