COLD
CATHODE FLUORESCENT SINGLE SURFACE MOUNT
LINEAR LIGHTS BY TAYLOR MADE PRODUCTS Taylorbrite's
flagship product line, the Cold Cathode fluorescent interior lights
offer features and benefits long-sought after by all users in the
Marine, RV and Truck markets. CCFs offer durability, long life,
low power draw, low heat, low profile/surface mounting, dimming
and attractive housing.
The ultra thin CCF tube (6mm) and TIR lens combine to form an ultra
thin light (0.9" in height) with no recessed parts. This enables
these lights to be mounted in constrained spaces, such as under
cabinets, and often results in greater headroom for occupants. Finished
in White Powder Coating, Gold, Chrome, and Brass Plating over a
Stainless Steel base surface with Diffused WHITE, Clear TIR or Red
TIR lenses to choose from.

CATHODE FLUORESCENT DIMMER SYSTEM
Background Some light sources are easy to dim. Incandescent
lamps are dimmed by simply reducing the voltage applied, either
directly or by various electrical wave-shaping techniques. However,
hot filament based discharge lamps, like fluorescents or halogens,
require a certain constant power level to keep the filament(s) hot.
Certain pulse shaping techniques can be used to provide at least
partial dimming for these kinds of lamps, but there is a price to
pay in terms of reduced life. A hot filament lamp running partially
dimmed may operate for less than half of its normal lifetime! Fortunately,
CCF lamps, with their robust electrodes, do not suffer from these
drawbacks.
Operation Taylorbrite's dimming system uses a technique known
as Pulse Group Modulation, or PGM. CCF lamps are best excited by
AC voltages in the 20kHz to 50kHz range. The ideal wave shape is
a "sine" wave, similar to the AC voltage wave shape found at a typical
wall outlet. This wave shape is preferred because it generates the
least amount of radio frequency interference (RFI). For the purposes
of this discussion, we will refer to one cycle of the sine wave
shape as a 'pulse'. Since the frequency of these pulses is fixed,
say at 20kHz, then one pulse will occur every 50uS (1/20,000 second).
This is very fast. So fast that if we were to remove one pulse,
the eye would never notice it, right? Not exactly. In fact, the
brain will average the pulses of light and will cause us to 'see'
a brightness level lower than what we normally perceive to be full-on.
The process of removing pulses from groups is called "Modulation".
Hence the term PGM means 'removing pulses from groups'. As long
as the pulse removal process continues to occur fast enough, the
eye and brain will continue to average the result. Very effective
dimming can be obtained down to 1% of full brightness! In order
for this system to function, the lamp's power supply must be designed
to implement this modulation technique. Consequently, a third wire
is supplied for the modulation control signal. This signal is generated
by the Taylorbrite dimmer module.
Benefits The true benefit of this system is the ability to
dim efficiently, without generating heat. Furthermore, dimming does
not impede the life of the electrode, nor does it create RFI. Because
a "signal" is sent from the dimmer that alters the frequency of
the sine wave, power draw of the CCF lights is reduced in proportion
to the light output. This is ideal for maintaining battery capacity
at night, when full brightness is not necessary, but a slight amount
of light may be desired.

COLD
CATHODE MR-16 Designed utilizing the latest in
fluorescent light technology, the 12 & 24 volt fixtures incorporates
a 2-1/2 watt ballast drawing less than 1/4 amp. The 110 millimeter
long tube is contained in a fully enclosed MR-16 (mirror-reflector)
bulb making it very rugged. The lamp provided lots of cool white
light (approximately 4000 Kelvin), roughly equivalent to a 20 watt
household bulb. The surface of the light reaches only 90 degrees
when running, eliminating that unexpected burning sensation when
you reach up to turn off the light without looking. Installation
is made easy with pre-installed spade connectors on the leads of
the ballast. The ballast can be placed anywhere in the circuit between
the switch and fixture. The lamp will fit any fixture that utilizes
an MR-16 bulbs and most Bi-pin (G-4) sockets as well. Average life
of this bulb is 10,000 hrs. Includes ballast. 30 degree lighting.
