Many people view cold cathode as the better alternative to LED and fluorescent.


Popular since the early 1930s, cold cathode is a dependable linear light source, which can also be sensually curved and provides an even, continuous bright line of light where required. With the development of the high


frequency low voltage electronic transformer, together with the advent of DMX Control, cold cathode lighting is an exciting light source, both practical and flexible. Though much maligned, cold cathode lighting has a long life expectancy and is more durable than some people expect. Even in a commercial installation, with extended usage, it should still perform for a minimum of some three or more. The Light Corporation has demonstrated to the entertainment industry, as well as in the domestic lighting market, just how cold cathode lighting could be used in lighting design schemes, in a cost effective and innovative manner, stripping

away the 'black art' surrounding it. ‘Cold cathode can be a stunning and most cost effective light source that is still, sadly, much undervalued and underused,’ believes Tim Henderson, director of The Light Corporation.


David Caddick, Henderson’s co-director, states: ‘For a light source that graced some of the most beautiful ocean liner interiors of the classic art deco restaurants of the 1930s, this light source deserves its rightful place dining at the top table of usable, creative light sources.’ The Light Corporation recently specified cold cathode lighting for Park Village West in London’s Regent Park. Park Village West is a grade two listed renovation where the owner requested a fun, funky colour change effect from the lighting design for contemporary addition to his home.


Colour changing red, green and blue (RGB) cold cathode lighting was used in a


concealed, linear format throughout the living/kitchen areas. This is controlled by a DMX signal dimming system, which was programmed to suit the clients’ moods at different times of the day. Cold cathode was chosen for its effectiveness and cost effectiveness, as the LED lighting option would have been a more expensive option used to create a similar effect. Paul Nulty, design director at Light


Bureau, believes that cold cathode, whilst not quite as efficient as T5 linear fluorescent lamps, is still more efficient than the best LEDs and is ultimately more versatile. ‘LEDs are still point sources and still


suffer inconsistency in colour temperature whereas cold cathode, if supplied by a good quality manufacturer, will be much more consistent,’ believes Nulty. ‘We also constantly face the age old argument that cold cathode is much more expensive than other sources… But quantity
