Note: Product availability is real-time basis and adjusted continuously. LED bulbs use significantly less energy and need to be replaced less often than other HID bulb types. Low pressure mercury vapor lamps are a highly efficient source of UV light, particularly short wavelength UV light (254nm and 185nm). It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. As pressure increases the chance of multiple collisions gets increased. LED HID-replacement bulbs are more energy efficient and need to be replaced less often than standard HID bulbs. In case of fluorescent lamp the mercury vapour pressure is maintained at lower level such that 60% of the total input energy gets converted into 253.7 nm single line. The high density of the vapor allows for light emission with a much higher radiance. Wattage equivalency is the amount of light (or brightness) a bulb produces in comparison to the power it uses (watts). Heraeus manufactures low and high pressure mercury vapour lamps used for applications such as photochemical processing, fluorimetry, mercury analysers, medical and environmental equipment, and fixed wavelength detectors.
