Par20 Vs R20 Light Bulbs

Producing more light per watt, CFL flood lights are excellent alternatives to energy-consuming halogen bulbs. Flood lights emit bright, highly concentrated light, making them ideal for use in outdoor landscape or indoor ceiling fixtures for directional or display lighting. R-type and PAR-type bulbs are popular flood light bulbs. They are often used in the same kinds of fixtures, including track lights and recessed downlights, among other flood light fixtures. The "R" in each of the bulbs' titles stands for "reflector" and the number stands for the bulbs' diameters in eighths of an inch. For example, R20s measure 20/8 inches (2.5 inches) and PAR30s measure 30/8 inches (3.75 inches). R-type bulbs produce soft-edged light, meaning that the light wraps around objects and casts diffuse shadows with soft edges. R-type bulbs are most often used in indoor-only fixtures and aren't as likely to be outdoor-approved as PAR-type bulbs. PAR-type bulbs, or Parabolic Aluminized Reflectors, cast more concentrated and precise light than R-type bulbs.
They are usually approved for use in either indoor or outdoor fixtures. Important Factors to Consider: Wattage: Low wattage = more energy savings; however, more watts = brighter light. Measurements: Will the bulb fit in your fixture? Beam Angle: Do you need a spotlight, or a wide-angle flood light? Lumens: More lumens = brighter light. Kelvin Temperature: Ranges from 2700K yellow light to 5000K white light.Kittens For Sale Cape Coral Wet Location or Outdoor Location Approved : If you are replacing an outdoor light.Lab Puppies For Sale In Athens Ohio R20 CFLs are soft-edged directional spotlights. Cat Power Sun Tour Set ListOffered in a range of beam angles and color temperatures, R20 bulbs typically measure 20/8 inches (2.5 inches) in diameter and 3.5 to 4 inches in length.
R30 CFLs are slightly bigger the R20s. They are offered in a range of beam angles and color temperatures and typically measure 30/8 inches (3.75 inches) in diameter and 5 to 5.5 inches in length. R40 CFLs are even bigger than R30s. They are also available in several beam angles and color temperatures, and they usually measure 40/8 inches (5 inches) in diameter and 6.5 to 7 inches in length. PAR20 CFLs are precise directional spotlights. Available in a range of beam angles and color temperatures, PAR20 bulbs typically measure 20/8 inches (2.5 inches) in diameter and 3.5 to 4 inches in length. PAR30 CFLs are slightly bigger the PAR20s. They typically measure 30/8 inches (3.75 inches) in diameter and 5 to 5.5 inches in length. PAR38 CFLs are even bigger the PAR30s. They typically measure 38/8 inches (4.75 inches) in diameter and 5.5 to 6 inches in length.Incandescent bulbs, which provide most home lighting, are used in products from nightlights to floodlights. The most common incandescent is a pear-shaped (A19) bulb with a medium-sized screw-type base.
Incandescent lights use electricity to heat a filament until it glows white hot, producing light. About 90 percent of the electricity used by incandescent bulbs is lost as heat. This style typically burns for 750 to 10,000 hours. Halogen bulbs contain a small capsule filled with Halogen gas, which emits a bright white light. Long life and full spectrum Halogen bulbs use less energy and last longer than standard incandescent bulbs of the same wattage. The life of these bulbs is around 2,000 to 10,000 hours or two to five years. Linear fluorescent bulbs, also known as fluorescent tubes, are more energy efficient than incandescents or halogens because they don't produce much heat. These are the thin, long tube lights often found in kitchens for under-cabinet lighting, or in garages, workshops, and basements. The tubes can last from 10,000 to 44,000 hours—10 to 40 times longer than incandescent lights. Fluorescent bulbs require and are powered by fluorescent ballasts. Compact fluorescents, also known as CFLs, provide as much light as regular incandescent bulbs while using just one-fourth of the energy.
For example, a 15-watt compact fluorescent light bulb yields the same amount of light as a 60-watt incandescent bulb. Compact fluorescent bulbs last about 10,000 hours—10 times longer than incandescent bulbs. High intensity discharge, or HID, bulbs include metal halide, high pressure sodium, and mercury vapor lights. As their name implies, HID bulbs emit a very large amount of light using relatively little power. They are a mainstay of parking lot, street, and warehouse lighting. Like fluorescent bulbs, HID bulbs also require a ballast. Stage bulbs and photography lights are specialized, high output lights used in the entertainment industry as well as in just about any stage or photography studio. Traditionally, these bulbs have used Halogen or HID technology, though LED stage lights are becoming more common. Miniature indicator bulbs are found in everything from heavy machinery to instrument panels. Though we carry hundreds of miniature bulbs, you can find the replacement you need by identifying the numeric code stamped on the base of your old bulb.
Automotive bulbs include everything from Halogen headlight capsules to the tiny incandescent bulbs that go in makeup mirrors and everything in between.
