3 inexpensive directional lamps
3 PAR light bulbs (Parabolic Aluminized Reflector - noted on box
as PAR)
3 dimmer switched cords (extension cord with a dimmer switches on
one end)
3 file folders
3 filters (red, green and blue)
9 clothes pins
masking tape
Assemble filter holders. Cut a hole the size of the lamp shade through
both sides of a file folder. Slip one of the filters inside the folder
and tape shut. Repeat for the other two folders and filters.
Screw in the PAR light bulbs then attach clothes pins to the edge
of the lamp shade. Tape the file folder to the clothes pins so that
there is a spacing between the lamp and the folder. This allows heat
to escape and not melt the filter. NOTE: DO NOT LEAVE LAMPS
ON UNATTENDED. THE FOLDERS AND FILTERS MAY BECOME HOT AND COULD BECOME
A FIRE HAZARD.
Plug lamps into the dimmer switches and plug extension cord into
an electrical outlet. Position the lamps so that they are the same
distance from and point to a common area on a white surface (such
as a projection screen). It may take some adjustment. When all three
lights are on and point to the same location on the screen , they
should give the appearance of white light.
By dimming the lights down and back up, the colored light mixes to
create a variety of colors. Numbers can be written on the dimmer switches
so that the colors can be described as a numerical value. To label
the dimmers, turn the lights all the way on and mark a 9 on the switch.
Then turn the dimmers down until the light goes off and mark a zero
on the switch. If more number are desired, estimate the numbers on
the switch between 0 and 9.
