a. Type: downlight/spotlight

b. Mounting: surface mounted

c. Lamping:

• 22 lamps
• LED

d. Construction: pin base

e. Manufacturer: ERCO

f. Study of photometrics:

• 7750 lumens
• 22 lamps/70 W

g. Material and finish:

• silver aluminum

h. Lensing:

• acrylic

i. Function:

Suggestion:

Based on natural light entering from the top and spotlights along the wall to help focus on whatever might be on the board, the only thing I would suggest is that all the lamps are consistent and that they all work.

Addams’ on Tate Street

f. Study of photometrics:

• spotlight – 300 lumens, 6000K, 3W
• downlighting -
• uplighting -

g. Material and finish:

• Aluminum coated shell (spotlight)
• aluminum (downlighting)

h. Lensing:

i. Function: movable and fixed

j. Ballasts:

• spotlight – 3
• downlight – 1
• uplighting – 1

k. Environment: Dry locations UL

l. Shielding:
Suggestion: 

I don’t have any suggestions for this place only because I think the lighting does well.  There’s spotlights to help with any tasks, there are recessed lighting to help add light to the spotlights and the wall sconces.  I suppose it would help to have some lighter colors in the space here and there to help accent the space.

 

Sketch Series 3

Last week in class, we learned about measuring light using a light meter.  We also learned the different types of measuring we could do with our light meters – such as light reflectance, incident light and percentages of both.  My partner, Brian, and I decided to test out the crit room in our building.  We measured the walls in the room and the light coming in from the top.  Below is a diagram of the measurements of light we observed.

Sketch Series 2: The Effects Light has on Materials

It is surprising how much light affects the color on a material.  Our latest assignment was to use 4 different types of lamps – flourescent, halogen, high-intensity discharge and LED lamps – and record the visual effects it creates against different colored textures.  Below are the results of this experiment.

Flourescent:

• a living room – a place to gather in and a place to relax
• dim light source on end table, ambient lighting
• low warm glow
• There are only two fixtures in the living room, a ceiling fan and an end table fixture.  The ceiling fan has incandescant lamps while the end table fixture has a flouresecent lamp.  Due to their difference, they are used at different times.  To  have a more ambient setting, I suggest including another lamp, possibly a floor lamp to cover the other part of the room.

Halogen:

• a home office – a place to do work (personal, school, or career oriented)
• desk light, tasking lighting
• bright cool
• It is hard to have recommendations for this light because the purpose is for tasks, which means that this light does well for clear visibility.  In the case of a design student, because it has a cool bright effect, it can distort warmer colors.  If there was a way to keep the halogen light but have a cover that can be moved to help when it comes to seeing colors accurately.

HID (high-intensity discharge):

LED:

• a bedroom
• task lighting
• although, the light is bright – it doesn’t travel very far
