FAQ
Frequently Asked Questions
No. While both use mercury vapor, they operate differently. A fluorescent lamp uses the mercury vapor's UV light to excite a phosphor coating on the inside of the tube, which then emits visible light. A mercury-vapor lamp's light comes more directly from the glowing vapor arc itself.
Because the mercury vapor emits most of its light in specific blue, green, and ultraviolet wavelengths, with less energy in the red part of the spectrum, resulting in a cool, bluish-white color.
Their sale and manufacture for general lighting are being phased out in many regions (like the EU and US) due to energy efficiency regulations and environmental concerns about mercury, in favor of LEDs and other HID lamps.
It refers to the state of the mercury inside the lamp. When the lamp is turned on, an electric arc passes through the gaseous (vapor) mercury, causing it to emit light.
