Recessed Lighting Guide
Meet all your aesthetic and practical requirements, and create the perfect lighting scheme with our line of recessed lighting products. Recessed lighting is ideal for shaping any look—dramatic or low-key, decorative or unobtrusive. You can light up the outside of your house with outdoor recessed lighting products from Dabmar. In choosing recessed lights, it is important to decide what effect you want to achieve. For example, to create a warm, bright kitchen, you might consider using incandescent fixtures that use “A†type bulbs. Here is an overview of the effects of different types of bulbs:
1. Incandescent—These bulbs provide warm, bright atmosphere for any interior. “A†type lamps or “R†type reflector lamps can be used to provide a brilliant glow. “A†type bulbs can also be used for wall washing, an effect in which light is distributed onto an entire wall for an even, ambient look. This technique is often used to illuminate wall art and to make a room appear larger in size. “R†type bulbs include a built-in reflector for the light. PAR type reflector lamps provide accents to important surfaces and colors.
2. Halogen—Highly efficient halogen sources deliver pure white regions of light to strategic areas within any interior. Various beam spreads can highlight large areas or pinpoint small objects. The brilliant, focused light is perfect for task lighting. In addition, low voltage halogen lamps are long lasting and offer more light per watt than standard bulbs. When used for high contrast accent lighting, the rule of thumb is to keep it three times brighter than surrounding light.
3. Compact fluorescent—For energy-efficient applications, use 9W to 42W compact fluorescent light sources. These bulbs provide reliable, consistent light and are ideal for commercial, office, bath and kitchen applications.
4. Metal halide—Use these high-performance bulbs in lobbies, museums, showrooms and any other application requiring brilliant, well-defined lightings in a large area. HID fixtures can be installed in new or existing ceilings and are available with standard or color-accurate ceramic metal halide sources.
In addition to light sources, it is necessary to consider two more components—the trim and housing. Since the trim is the most visible part of the fixture, you should choose one according to your visual preferences. Opt for a simply finished trim that easily blends into the décor of the room or make your aesthetic mark with a flashy chrome or decorative glass design. Accent lighting becomes particularly effective with trims that include eyeballs and adjustables. The following lists the technical specifications of some of the housing (above-ceiling component) options:
Economy Incandescent
1. Nail-free bar hangers with slots for T-bar grid.
2. Knockouts on corner for tie-down to ceiling grid.
3. Brackets on plaster frame allow bar hangers to be repositioned 90 degrees if desired.
4. Airtight feature on selected fixtures restricts airflow to 2 cubic feet per minute maximum. Conduit and screws are gasket sealed to comply with WSEC standards.
5. Socket plate adjusts vertically for best possible light distributions.
6. Wing nut removes to allow complete removal of socket plate to install either gimbal ring or eyeball type trim.
7. Internal quick connects provide instant, trouble-free electrical connection, eliminating the need for wire nuts and reducing labor time per fixture.
8. Large j-box provides seven 1/2″ knockouts and four Romex pry-outs with automatic strain relief.
9. Allows maximum of 8 #12AWG conductors rated for 90 degrees Celsius.
Low Voltage Halogen
1. Magnetic class “H” transformer features internal thermal protection device.
2. Porcelain 5.3 mm base Socket with aluminum heat dissipation shield.
3. Low voltage trims support MR16 light sources and include tempered UV and shatter resistant shield.
4. Teflon jacket with internal strain relief protects leads from mechanical and heat damage.
5. Large j-box provides two 3/4″, three 1/2″ knockouts and four Romex pry-outs with automatic strain relief.
6. Allows maximum of 8 #12AWG conductors rated for 90 degrees Celsius.
7. Nail-free bar hangers with slots for T-bar grid.
8. Knockouts on corner for tie-down to ceiling grid.
9. Brackets on plaster frame allow bar hangers to be repositioned 90 degrees if desired.
Compact Fluorescent
1. High quality architectural and commercial 6″ and 8″ reflectors provide maximum efficiency with minimal lamp image or glare.
2. Low iridescent reflectors are also available in clear and designer finishes.
3. Socket cup affixes to horizontal reflector or dual set screws, allowing for quick installation and removal with an optional third locking screw provided if permanent setting is desired.
4. Self flange is available with low iridescent 6″ architectural/commercial, and standard on all 8″ reflectors.
5. Reveal on architectural/commercial frame-ins accepts 5/8″ drywall or acoustic material.
6. Universal butterfly brackets adjust vertically and accept c-channel bar hangers (NRA-38), flat bar hangers (NRA-28), or standard 1/2″ conduit pipe (bar hangers not included).
7. Large j-box provides seven 1/2″ knockouts and four Romex pry-outs with automatic strain relief
HID Metal Halide
1. High quality architectural and commercial 6″ and 8″ reflectors provide maximum efficiency with minimal lamp image or glare.
2. Neck on all architectural reflectors has slots to allow vertical adjustment of socket for best possible light distribution.
3. Die cast socket cup contains 4KV pulse rated socket and draws heat away from the socket for best light sources performance and reliability.
4. Self-lipped flange is standard on all 8″ vertical reflectors.
5. Ballasts available either as magnetic with dual 120V/277V input for standard PAR or ED17 sources or voltage specific electronic solid state for color consistent ceramic metal halide sources.
6. Thermal protection for magnetic or electronic ballast
Sloped Ceiling—Flexible angled housing to meet the challenge of providing vertical illumination from a sloped ceiling. These fixtures are complete with dual-angle adjustments and ellipsoidal trims to compensate for sloped angles. Available with either incandescent or energy-saving compact fluorescent light sources.
1. Dual brackets allow housing to be adjusted within plaster frame and socket concurrently adjusted with the housing to achieve a perfect vertical path of illumination from a sloped ceiling. This also allows for horizontal adjustment to insure that lamp is centered in a vertical position for a vertical path of illumination from sloped ceiling.
2. Nail-free bar hangers with slots for T-bar grid do not require additional hardware.
3. Knockouts are provided on corners for tie-down to ceiling grid.
4. Brackets on new construction frames allow bar hangers to be repositioned 90 degrees if desired.
5. Large j-box provides seven 1/2″ knockouts and four Romex pry-outs with automatic strain relief.
6. Allows maximum of 8 #12AWG conductors rated for 90 degrees Celsius.
Explanations of technical terms
airtight—energy-saving feature that restricts airflow to 2 cubic feet per minute maximum; prevents drafts and keeps heated or cooled air from escaping
baffle—bulb frame that reduces glare by positioning the bulb back from the trim
elbow—adjustable bulb frame that protrudes out to provide dramatic, concentrated light
eyeball—a rotatable, directional bulb frame that is mounted on a swivel; provides focused light for accent or task lighting
