What is cold cathode?
Cold cathode is a specialty fluorescent lamp type. Because of its unique construction, longevity, and customizable lamp shape capability, cold cathode has always been the first choice for absolutely continuous indirect illumination. The “cold” in cold cathode refers to the lamp’s electrode which, in relative terms to a traditional fluorescent lamp, operates at a much cooler temperature.
What’s the difference between the new Slim luminaires and the older luminaire designs?
The focus on energy efficiency, especially in the context of LEED-compliant projects, has moved to the forefront of almost all lighting design projects. The Slim luminaires are physically smaller than any product we have ever manufactured (60% smaller than our traditional products), and they are very energy stingy. The “H” prefix in our HFCLS-Slim and HCLS-Slim designates “high efficiency.” These products produce ample lumens (up to 330 lumens per foot), consume approximately 5 watts per foot and boast a field-proven 100,000 hour lamp life.
Our existing CLS and FCLS product lines are available with high-output ballasts, which require a dimensionaly larger luminaire to accommodate the larger ballast size. However, if light output in the range of T8 or T5 fluorescent is required, these products are very appropriate.
Doesn’t cold cathode require high-voltage?
Not anymore. New electronic ballasts now power all of our products. These new ballasts are small, silent, highly efficient and operate at the same voltage as a Slimline fluorescent lamp.
How are the colors made?
Phosphors that coat the internal surface of the glass tube glow in the presence of the internal gas discharge.
Where do I use cold cathode?
Cove and concealed lighting effects comprise the majority of applications. Exposed fixtures can also be used when a continuous line of light is desired.
How many colors are available?
11 shades of white and over 20 pastel and neon colors.
Can I use this in LEED-certified projects?
Yes. Our new High-Efficiency products consume 4.5 watts per foot, will last 100,000 hours and produce more light than comparable LED products.
Is the bulb in the Flexible Cathode Light Strip (Model FCLS) field curvable?
Only the fixture is field curvable, the lamps still must be made to the desired dimension or radius at the factory.
Can cold cathode be used outdoors?
Yes. Our Exterior Cathode Light Strip (Model ECLS) is UL wet-location listed, and carries an IP-65 rating.
Can I specify Cathode Lighting Systems products in other countries?
Yes. Our products also carry a CE approval that is recognized worldwide.
