![]() ![]() This type of lighting provides the highest-quality light in terms of pure color rendering. These also can be used for industrial work lights and in film or television studios.Double-ended bulbs are the standard for floor or wall-mounted torchiere lamps that direct light upward from an inverted shade to produce abundant glare-free lighting.Theaters use colored halogen spotlights and flood lamps for stage productions.Spotlights emit a more focused beam of light. ![]() Flood lamps provide a large area of illumination and may be used indoors or outdoors, depending on the glass used for the bulb.This makes them just as versatile as incandescent or LED options. The most common halogen light bulb types include the same basic varieties found among other kinds of bulbs. Halogen bulbs come in many shapes and sizes. Additionally, they are a more environmentally responsible choice because they do not contain mercury, as CFLs do. In applications that call for something closer to natural sunlight, these This is because the light they give off tends to be warmer and because they reach full brightness immediately. They do consume more energy than LED or CFL options, but typically still are seen as more appropriate replacements for older models of bulbs. Halogen light bulbs are more energy-efficient than traditional incandescent fixtures. Halogen light fixtures also may come with dimmer switches so that the brightness can be adjusted. They are valuable as well in any other situations and areas where high- quality, pure white light is essential. Halogen lights are commonly used for track lighting, projectors, stage and studio lighting, medical equipment, work lamps, flood lamps and reading lamps. They use a tungsten filament in a high-pressure bulb filled with gas. Temperature requirements: none Operate well in any temperature requirements.Halogen light bulbs are known for their brightness and their ability to last longer than standard incandescent bulbs.Efficacy: Excellent (70-100 lumens per watt).Ballast and transformer: Require an electronic or magnetic ballast.Other HID sources-sodium and mercury vapor: 30-50.Metal halide lamps: CRI values: 70s or 80’s.Color rendering index: 70-90 (moderate to good).Initial Cost: High due to the technology involved.The technology behind HID sources relies on creating an arc of electricity in an environment of the metal Various types of light bulbs include high-intensity discharge lamps represent a large family that includes sources like High-Pressure Sodium, Metal Halide, and Ceramic Metal Halide. Temperature Requirements: Operate well in any temperature requirements.Generally lasts 3000 hrs.’ but engineered to last 10000 hrs.They are 50% more efficient than standard sources, but still, there is wastage of electricity.Can be dimmed with simple wall box dimmers, which regulate the quantity of electricity delivered through the filament.Ballast and Transformer: Few Halogen Incandescent sources may require a transformer.Efficient than standard Incandescent sources but are short-lived when compared to sources like fluorescent, LED, and High-Intensity Discharge. Initial Cost: Moderately expensive due to the cost of technology.They are basically a refined version of standard incandescent sources. Halogen incandescent sources are named for the halogen gas that they contain and the quartz outer bulb that surrounds their filament. Small and hot, Halogen sources deliver clean, crisp, easily directed light that is useful for creating focused shapes of light, accent surfaces and objects, or for twinkling use as base lamps for visual interest. Lighting Pollution: They produce direct glare as a point source.Temperature Requirements: Operate equally well in any reasonable temperature condition. ![]() They have shorter service life than other light sources. Incandescent sources are expected to have a lamp life of about 1000 hours.They deliver more heat than light which results in a large quantity of wasted electricity.The larger the source, the more inefficient it is to gather up the light and drive it out in a specific direction through optical control.Instant-on/off: filaments heat up very rapidly.Dimming: Can be dimmed simply by lowering the amperage (quantity) of electricity.Ballast and Transformer: Do not require ballast and transformer. ![]()
