For this assignment, we were assigned the task of observing the appearance of various fabrics under different lighting conditions. With every switch in bulb and light type, the color and texture of the fabric would alter.
Types of Fabric Used:
Red Burlap
100% Jute
Blue Organza
100% Nylon
Brown Garment Lining
100% Polyester
Beige Linen
100%Flax
Types of Light Used:
Compact Fluorescent
Incandescent
Metal Halide
Type 1:
Compact Fluorescent
-Used in bedroom to provide lighting other than overhead fan/light and windows(which provide natural light).
-Space in which light source is in is used for sleeping/lounging/homework/eating/etc.
-Needs to have light source on most of the time, except when sleeping/resting.
-Used for both task and accent lighting
-lights up dark corners
-provides lighting to light up nightstand
-Easy to access
Type:
-13 watt= 60 watts bright light
120-VAC
60Hz
210MA
Horizontal Lamp Luminaire
-The light source has a very white and bright light
-Seems to wash out the yellow color of the wall behind it
-Brightness and direct glare is relatively muted by the black lamp shade.
-The room gets a good amount of light. There is no issue where lighting is concerned.
-Room needs no change, it works fine the way it is
-Amount of light is very flexible with the amount of interior lighting in the space.
Observations:
Burlap:
Red looks more pink
Makes shadows and highlights stand out
brightness in light pronounces the texture and weave pattern of the fabric
Organza:
Can see the luster and shine
Appears blue with slight hint of purple color
brightness almost gives it a wet, shimmery effect
Garment Lining:
Looks very solid and chocolate brown
Brightness highlights the luster and shine
Linen
Does not have much influence from the light source
matted and mildly dull.
Does not reflect the light much. This is to say there is no specularity
Beige in Color
Burlap
Type 2:
Incandescent
-Used like the fluorescent, in a bedroom
-Provides task and ambient lighting
Placed inside of a floor lamp, next to the bed
-Emits a soft yellow glow
Type:
150Watt
120Volt
Characteristics:
Highly Preferred For Color
90-100 CRi
Warm Tone(2500-3500 degree Kelvin)
Short Life
Low Cost
High heat output
Easily dimmed
Lighting Fixture: Horizontal Lamp Luminaries
-Light source has dimming feature
-Soft, subtle glow does not over power space.
-Lamp Shade adds to warmth and reduced glare
-Makes the yellow paint appear more warm and yellow
-Emits right amount of light in the space
-The only concern with this light is the durability and lifespan.
This light stays on most of the day. It needs to have a bulb that will keep up with that high demand without burning out or overheating.
Observations:
Burlap:
True Red rendering(displays the warmth of the color)
Weave and dimensions are not as defined as fluorescent
Little to no specularity or reflectance
Organza
Renders less intense of a blue this time
Less purple and more pale, greyish blue
More luster and shimmer when placed under shade, in direct glare
Garment Lining
Richer warm, Chocolate color.
Much warmer than Fluorescent
High shine and luster
Linen:
Warmer Tone than when placed under fluorescent
Warmer colors in the weave of the fabrics
more pronounced depth and color change.
Burlap
Organza
Garment Lining
Linen
Type 3:
Metal Halide
-Used in kitchen where ceiling heights are high and changing light bulbs is inconvenient
-Light needs to light up entire kitchen space.
-Serves as both task and accent light
Since it is track lighting, it lights up the space, but also accents the areas as well.
Emits a bright, cool tone
Type:
Metal Halide(ceramic)
W=39T6
Color Series 3K
Track Lighting System
Characteristics:
CRI:70-90
High Cost
Good Efficiency
Moderate Life Span
Good Color Rendering
Sharp/ Focussed
Track Lighting:
Ceiling mounted
Individual lights can be rotated to illuminate specific/ desired areas.
Suggestions:
I don't know if I would use MH lights in kitchen spaces.
It seems an Incandescent would work just as well, and it would be far less expensive to maintain.
Since there is only tracking, I would add additional area lights.
Perhaps even some under-cabinet lights as well.
Additional lights would add flexibility to the lightness of the room.
Observations:
Burlap:
Good Color Rendering
Not pink like fluorescent
More similar to the Incandescent light
Pernounced depth and weave are visible with this light
Organza:
High Luster/Shine
Wet Look
Slight Indirect Glare
True blue color rendering
Garment Lining:
High luster/ Shine
More Indirect Glare
Chocolate in color
not as warm as incandescent
Linen:
Not as warm as incandescent(as far as color is concerned)
Dull(no luster)
Renders the beige color very well(with a hint of olive undertone).
