Before you start working with a recessed backlight, take some time to familiarize yourself with the basics. I have been a power contractor for 8 years and have dealt with countless recesses able to light installations. I will go through the styles and types of light, as well as basic information about the layout and design.
How do you know what size is right? Standard light sizes are 3 ", 4", 5 "and 6". My rule - the lower ceiling, the smaller recessed. For ceilings less than 8 feet, I recommend 4 "banks." 4 notch lights also work well for accent lighting, since the bright opening is small and less visible. A typical installation will use 4-inch light to highlight a work of art. For ceilings of 8 feet or more, 5-inch lights can work fine, although they can also be used for accent lighting, if necessary.
In addition to the size of the notch can also glow in different voltages. Standard incandescent bulbs can operate at 120 volts and use 120 volts light bulbs. Incandescent bulbs are the oldest and most reliable as well as the least expensive. Incandescent bulbs or 120 V are also cheaper than low voltage bulbs. Another type of cutout may be low voltage. Low voltage indicators are connected to a voltage of 120 V, and then use a transformer or ballast to reduce the voltage to 12 V. Low voltage notches can use less energy than incandescent lamps, but are more expensive and have higher prices. In addition to the higher price, a low voltage base also has a transformer that needs to be replaced every 4-6 years.
The recessed light can be a ring and a reflector that covers the inner light housing. Trimming is usually one piece, and it is installed in the body of the housing in front of the lamp. The purpose of trimming is to reflect or target light from a recessed can while covering the body of a metal case. Trims come in different styles for a specific use. Below I have outlined some of the basic types of slats available. Baffle Trim: Used in most common lighting applications. This is a standard white ring with a white or black interior. Eyeball trim: Eyeball trimmers can usually be adjusted 360 degrees and can be aimed at an angle of 30 to 45 degrees. This is useful when light should be directed in a specific direction or area. Wall mounted washbasin: commonly used along walls. Trimming is similar to finishing a partition, but half of the open light is closed. Half a cap directs light in one direction, creating a washing effect. Reflector or Alzak Trim: These trimmers usually have a white trim ring and a metallic gold or silver inner reflector. These reflectors can create dramatic moments, and the gold trim can heat the light color. Shower or steam room trim: these trimmers are commonly used for showers and baths, but can also be used outdoors and in other wet conditions. This style lining has a protective cover over the lamp, so water cannot enter the light and is usually limited to a 40 watt lamp. Custom trimmers: custom slats are available from some manufacturers, and many of them have 10 or more colors in most standard styles. Custom color trims are usually not stock items and are usually not returned.
Before installing any built-in backlight, carefully read this section. Lighting devices may have different sizes. Standard ratings are IC, not IC and Air. If your recessed can be installed in an insulated ceiling space, you must install an IR insulated enclosure. Rated enclosure without IC, installed next to the insulation, is flammable and extremely dangerous. My recommendation is that housing with an IC rating be used in each application to avoid potential problems.
Ic. Rated power: IR cutouts should be installed where the insulation will be in direct contact with the light housing. An IC rating means that the groove body may remain cold enough to touch flammable materials and not pose a danger to fire.
Non-IC Rated: Non-IC rated notches require no contact with insulation or flammable materials. A housing with a rated current without IC becomes hot during use and has the ability to ignite flammable material within 3 inches of the housing.
Air-Tight Rated: Air Tight rated means that when the built-in light is fully assembled and installed, it forms a tight seal. This seal stops any loss of heat or cold air and keeps your home more energy efficient.
When you choose a recessed lamp, be sure to consider the type of lamp. Power, size, brightness and cost can vary greatly depending on which style of light is chosen. Make sure you read the instructions in the manual to make sure that you are setting the correct wattage and lamp size. If you install the wrong lamp, it can quickly burn, not work at all, or even worse than heat, and cause a fire hazard. Below are the most common types of lamps for recessed lights.
Incandescent bulbs: Otherwise, called “A” lamps, are inexpensive and excellent for all types of lighting. They are completely blurred and easily available for purchase in a large number of stores. Typical powers are 25, 40, 60, 75, 100 and 150.
“R” or “BR” lamps: usually have a cone shape and have a reflector that helps diffuse light. They come in different light spreads, such as; wide streams, narrow stream and spot of light. They are also available in different sizes. Typical power: 45, 65, 75, 90 watts.
Halogen: Halogen are similar in size and shape to the “R” bulb, but produce a brighter and whiter light. They are more expensive than lamps "A" or "R", but have a slightly longer lifespan. They come in different light spreads, such as; wide streams, narrow stream and spot of light.
Low voltage lamps: low voltage lamps are the most expensive and have a longer service life than incandescent lamps. They use less energy than other bulbs, but should be used with a lamp luminaire with a transformer that reduces the voltage of 120 V to 12 V. An example of a low-voltage light bulb is the MR-16.
And last but not least: I will cover the housing with a recess. There are two different styles that are created for a particular type of installation. If you chose the wrong enclosure, this can make installation difficult or even impossible. Please read the names and descriptions carefully so that you can understand which enclosure is suitable for your installation. New ceiling enclosures are attached to the ceiling pillars before installing the ceiling surface. If the area above the ceiling is available, these lamps can also be installed from the inside of the attic. Remodeling hulls are used on existing ceiling installations and allow you to perform most of the installation from the bottom. Reconstructed cans are not attached to the ceiling frame, but instead have clamps that secure it to the opening of the drywall.
