harm will be done to lamp (a) “on” with the fan “off”. If the Dual TripleBright II is installed
vertically the fan should be positioned at the bottom so it blows cooling air up.
F. REPLACING THE SHORT WAVE FS-60 FILTERS and OTHER FILTERS
Reasons you might want to replace the glass filters in your Dual TripleBright II are included
below. If you are already familiar with this subject, skip down to the next paragraph. Long
wave filters never need replacing since they do not solarize or wear out.
Reasons you Might Want to Replace the SW Filters
Because the Dual TripleBright II is so powerful, more short wave ultraviolet passes through
the FS-60 filters than in many other displays lights on the market. Short wave ultraviolet
radiation causes a chemical reaction in the filter glass that reduces the transmission of the
253.7 nm [UV] wavelength with time. This is called solarization. The visible light that you
can see transmitted through the filter does not change as the filter solarizes, and so in no way
indicates the degree of solarization. This solarization effect is a function of the amount and
duration of short wave ultraviolet light exposure. In addition, if the light is stored in a damp
or humid environment, a dull white coating can form on the glass that also causes a reduction
in 253.7 nm UV transmission. The coating is caused by a chemical action with the moisture
in the air. The coating can be cleaned off, but the glass under the coating may have already
been affected, which might result in reduced transmission. Fingerprints will also absorb very
small amounts of UV so these could be cleaned off if desired. The filters can be checked
periodically for solarization by obtaining an ultraviolet radiometer and measuring the actual
253.7 nm transmission. When the light is not being used, turn it off to reduce the filter's
exposure to excessive ultraviolet. Turning the light "on" and "off" frequently has no effect on
the life of the lamp, but it has a positive effect on the life of the filters (with less ultraviolet
exposure). The SW filters in the
Dual TripleBright II should last a long time depending on
how humid the environment is. Recent tests indicate that the life of the FS-60 filters is about
7,000 hours (based on a transmission of about 25% at end of life). When not in use, the light
should be stored in a dry environment to protect the filters. Long wave filters do not solarize
so they should never wear out.
Removing Glass UV Filters
To remove the glass FS-60 SW filters (or FL-60 LW filters); first unplug both the yellow and
blue and black power cords. Then: (1) twist the knurled knob attached to the cover that holds
the cover on. (2) Let the cover swing free. (3) Side the cover (on the slip hinges) towards the
cord end of the light and remove the cover. (4) Remove the filters one at a time. Note, that
the points of the sheet metal screws are very sharp so be very careful. (5) Remove the three
screws on one side of a filter bracket and loosen the three screws on the other side. (6)
Remove one of the metal filter bracket holders and slide the filter out. (7) Do the same for
the second filter. Note the filter brackets have aluminum “fingers” that hold the filters.
Before installing new filters, you may wish to put some spacer or black tape between the two
filters so there will be no glass-to-glass surfaces touching. The tape now between the old
filters might degrade. To install a filter just reverse this procedure. Use care when installing a
new filter so that the aluminum cover or metal filter bracket holders do not put undue stress on
the filter, but make sure that the fingers of the brackets are over the filter (and not just on the
