KITCHEN LIGHTING BASICS
ID-240 Interior Design II
TYPES OF LIGHT
 General: 35 – 50 Foot Candles
 Task: Where work is done
 Accent: For visual interest
 Make sure if mixing lamps (LED,
Incandescent or Fluorescent that you
keep the temperature the same color.
TYPES OF LAMPS (BULBS)
1.
Incandescent: generate light when an electric current heats the lamp’s tungsten
filament until it glows.
2.
Halogen: A type of incandescent lamp that contains a small amount of halogen gas
within the glass bulb that impedes the evaporation of tungsten. They are more
efficient, produce a whiter light and last longer. They can get extremely hot.
3.
Fluorescent: Invented in the 1930’s. Uses the principle of fluorescence in which
minerals exposed ultraviolet light are caused to glow. These lamps typically contain
small amounts of mercury. Requires a ballast to regulate the power flow to the lamp.
4. HID: High Intensity Discharge – used for street and parking lighting and large indoor
spaces like gymnasiums and industrial work floors. Can get hot. Metal Halid Lamps can
produce good color quality. Sodium lamps have poor CRI.
5.
Light Emitting Diodes: (LED) Latest technology
A Lamp: Incandescent Lamp (pear shaped) Typical A-19 Lamp
LAMPS
R Lamp: Contain an internal reflector to direct light in one direction Common: R-20, R-30 and R-40
T Lamp: Tubular Lamps: Fluorescent lamps contain a small amount of mercury. Typical sizes: T5 & T8.
HID: High Intensity Discharge: MR-16 (Multifaceted Reflector) Low-voltage, typically 12 volts.
Lamp sizes: diameter is measured in 1/8”. For example a T-8
tube is 1” in diameter while a T-5 tube is smaller at 5/8”.
LED – LIGHT EMITTING DIODES
Newest technology. An LED is fundamentally
different than other lamps. No filament, gas or
fragile glass enclosure. It is an e semiconductor
device.
This is a low voltage method that requires a
“driver” – similar to a ballast.
These lights are more expensive but can last
upwards of 50,000 hours vs. 750 hours for a typical
incandescent lamp.
COLOR RENDERING/TEMP
 Color Rendering Index (CRI): The measurement that
illustrates the light source’s ability to render the
color of objects correctly. Scale of 0 – 100, 0 being
bad. 80 – 100 CRI is recommended. Natural light
has a CRI of 100.
 Degrees Kelvin: Color Temperature – Warm, Neutral
or Cool light. Incandescent lamps are 2700K
TYPES OF LUMINAIRES
RECESSED DOWNLIGHT
 Can be equipped with incandescent, halogen, compact fluorescent, HID, or LED
lamps
 Consists of two parts: the can or housing above the ceiling and the trim kit
installed below the ceiling. The housing must be suited fo rthe application:
 T= thermally protected. Common for most commercial installation with a dropped
ceiling
 IC = Insulated Ceiling – used if cans will be in contact with insulation materials found in
attics of homes.
 Damp Locations: Exposed to moist air, but not diret water spray or rain
 Wet Locations: Exposed to direct water spray
 Emergency fixture: has a battery backup for 90 minutes
ADJUSTABLE FIXTURES
Adjustable fixtures allow light to focus on
objects of interest such as art, signage, or
interior surfaces.
