Cold Cathode: The long lasting and energy efficient architectural lighting
Suitable for outdoor and indoor use, cold cathode has many advantages over other forms of lighting
Using a cold cathode system releases the architect or lighting designer from having to conform to standardized, often inflexible stock systems from a lighting manufacturer’s catalogue. Cold cathode is unrivaled in its design flexibility, wide range of colors, high energy efficiency, low maintenance requirements, and lamp life is not affected by on/off cycles.
Cold cathode is the product of choice for architectural designers, property developers, and owners of commercial and residential com-plexes. Design quality into your signage and displays by specifying the finest products on the market.

The word “cold” actually refers to the temperature of the tubes when they are on: The tube rem ains cold. Which is one of the reasons why “hot cathode”the industrial name for fluorescent tubes) cannot be used for exposed outdoor applications: Rain on a hot tube could cause the glass to break and cause a short circuit.
The efficacy (lumen per watt) of cold cathode is approximately 40% higher than fluorescent tubes, and with an energyconsumption of 20-25 watts per linear meter and a lamp life of up to 50,000 hours, cold cathode easily outperforms other forms of lighting.
APC works exclusively with the best raw materials, imported from the US and the EU. The high quality and reliability of the cold cathode tubes, electrodes, and transformers ensure that our customers get value for money.
APC has designed, installed, and maintained the cold cathode lighting system for:
- Kasikorn Bank
- GMM Grammy
- Bangkok Bank
- TMB Bank
- Government Provident Fund (GPF)
... and many, many more...
To ensure safe and proper installation, we have trained a team of technicians and we give warranty on our installation works as well as a limited war-ranty on the product itself. We also provide maintenance services to ensure that you will always find your landmark completely lit. |
