What is a Mercury Vapor Light Bulb? - Home Stratosphere Mercury vapor lamps are metal vapor lamps based on light emission from mercury (Hg) atoms. Mercury vapor vs. The Color Rendering Index (CRI) gives a rough color fidelity "score" of how a particular light source renders a palette of pastel colors, while a new method, known as TM30-2015, gives a significantly more accurate assessment of color fidelity. All these things are HID variants and all use mercury (or sodium) but the ones called "mercury vapor" (and sodium vapor) are a monochromatic light that's not terribly usable for serious lighting unless you absolutely have to. Mercury vapor is not very energy efficient. LEDs generally have better color temperature options than HID. Many manufacturers have reduced mercury content even further some to as low as 1 mg per bulb. Based on cost savings, quality, and political factors - our experts here at Action Services Group help to define why it may be . This High Intensity Discharge (HID) Mercury Vapor light bulb offers efficiency and long life up to 10,000 average rated hours. 351.

Mercury Vapor vs. Cool White Bulb Color. The temperature of mercury-based lamps can reach 500 degrees F (260 degrees C) or higher during operation. Therefore, most mercury vapor lamps have a phosphor coating that alters the color temperature and improves color rendering to some extent. Mercury vapor lamps are often mixed with other types of lamps to smooth out the color spectrum, especially when good video is a consideration. (For an explanation of these terms, see last week's column.) Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. A value of 100 CRI indicates perfect color rendering. HID lamp color temperatures are determined by the materials used to generate the light. Mercury Vapor Bulb FACTS 1) Self Ballasted Mercury Vapor (SBMV bulbs) bulbs have a filament inside that works as a ballast. Mercury is a naturally occurring trace metalloid element and known neurotoxin with atomic symbol Hg, atomic number 80, and atomic weight 200.59. Color Temperature.

And Mercury vapor (gas) is found in some particles of light. The temperature of mercury-based lamps can reach 500 degrees F (260 degrees C) or higher during operation. I like mercury vapor better than HPS or MH, metal halide contains more mercury in it than mercury vapor and always tends to explode, also high pressure sodium creates an unpleasant orange haze at night (even full cutoff ones) and isn't very visable at night. Mercury Vapor Standard HPL-N 250W E39/41 HG.1CT/3 Mercury Vapor lamps feature low initial cost, but have higher operating costs than HPS or Metal Halide due to its lower efficiency. Mercury: Mercury is an essential element used to create light in a fluorescent bulb. Mercury vapor is the oldest type of high-intensity discharge (HID) lighting. The lamp is. My questions: 1. Color rendering index 40 Operating Position Universal Time to hot re-start 10 (max) min ELECTRICAL CHARACTERISTICS Nominal lamp wattage 1000 W Nominal lamp voltage 265 V . This filament is the weak point in the bulb. A higher color temperature and CRI also increased the visual acuity of each application making it easier to see and read under Metal Halide lighting. This bulb is designed for indoor and outdoor applications, such as overhead lighting in factories . Use them to illuminate large outdoor areas, such as parking lots. It is named after the Roman god Mercurius (), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Brochures & Spec Sheets 2.
