Saving energy resources has become a very important policy today. 


The HOTFIL system offers many advantages over known lightsources for applications in internal illumination, sign illumination and architectural accent lighting.


Colors and shapes are versatile like known neon sign tubes; efficiency and installation is equivalent to standard T5 fluorescent lamps.


The superiority of the system regarding luminous efficiency, energy consumption, investment and operating cost is shown in a scientific comparison between LED's, standard neon tubes and HOTFIL tubes.

The manufacture of individual neon/cold cathode tubes requires a lot of experience and proper shop equipment.


Lamp quality can be improved remarkably by use of the semiautomatic HOTFIL processing system. It guarantees constant quality by maintaining constant parameters during electrode processing ("conditioning") and evacuation. Standard neon/cold cathode tubes can be processed as usual with the system connected.


HOTFIL tubes can also be operated on high voltage transformers; for manufacture, either a vacuum oven or a standard bombarding/pumping system equipped with the HOTFIL conditioner is sufficient.

For sign /electrical installers the HOTFIL system offers the advantage of power supplies running below 1000 volts. No hassle with UL2161, no high voltage requirements according to NEC, no high voltage electrician license necessary (applies in some countries).


The intelligent and extremely small electronic ballast "mini-EPS" fits anywhere and makes lamp life independent on number of switching cycles.


Quick and simple installation of HOTFIL tubes due to T5-clip- on connectors - like T5 fluorescents.

Hotfil-tubes can also be retrofitted in existing high voltage cold cathode/neon sign installations with currents of 75mA or higher without rewiring; energy savings up to 30% possible by simple tube change - at the same light output!
