The best of contemporary design and engineering. The motor is the same big, strong metal gear, long life, as was in the original Prisma. Vectors of light are being rotated as they pass through each material which is very different from color filtering.

It turns out, the color changes have to do with polarized light and a phenomenon called bi-refractance. Then you walk around while watching the clock and surprise - the colors change depending on your viewing angle! Plus, inside the clock you see a clear secondhand disk changing through a magenta-blue-green-yellow color range, twice/minute as it rotates. There is something else going on! First you intuitively sense - something is wrong with the colors. What's so special about polarized light color changing? There are continuously changing colors and surprising color 'shifts' when the secondhand disk overlaps the minute & hour hands. The lamps are long life LEDs , they slowly lose brightness – down 30% in 15-20 years. In 2012 we introduced the Prism TL with the thick edge-polished acrylic on the front. In 2001 we introduced the PRISMA II, an updated version of the Prisma changing clock from the 70's. This is what the upper corners look like with plastic, chrome-color sides. The sides look better than the picture above the below picture is better. Note the different color of the background depending on if you are viewing the clock from the left or the right. A list of all the possible changes are listed in the table above. Specials versions: Modifications are available for a flat $19 extra handling charge. A wonderful improvement on a classic design. No more fluorescent lamps to deal with like the original Prisma (not referring here to the cold cathode lamps in our first Prisma II, but the original Prisma from the 1970's). This is accomplished with 20 red, 20 white, 20 blue, and 20 green Superflux LEDs driven by a microprocessor. Also, a new brightness adjustment to brighten it up for an office or dim it down for a bedroom.

Now with more colors, better colors, and colors that do not repeat exactly twice/minute like the old versions, plus now even the background color changes. In the bottom right is the small, now optional, (original 1970s) eccentric second hand disk. In the top-left of this picture is the newer, large dual disk, more color active, second hand. This also has the advantage of more color activity. The larger second hand disk's rotation over the hour and minute hands means they are easier to see more of the time. It has been a problem even in the originals from the 1970's. The reason for this change is customers irritation at the hour and/or minute hands becoming very hard to see for several minutes twice every hour.

Most customers just order this standard version.Īttention: We have changed what is Standard () The larger second hand disk is now Standard, and the smaller eccentric disk is Optional. T he Prisma TL has been designed to come close to the original Prisma from the 1970's, but with the improvement of the large dual disk second hand and LED's for the internal light source (no fluorescent lamps to replace) giving you more and better colors.
