ACDC supplies cold cathode for a wide range of projects.


lamp life of typically 10,000 hours. A cold cathode lamp does not operate in this manner and no heating is required – hence the name cold cathode – and the operating lifetime of an ACDC tube is around 45,000 hours.’


Another benefit of cold cathode that


Wolstemholme points out is the continuous lighting effect created by the ‘turned-back’ electrodes. Fluorescent lamps do not light right to the end and furthermore, this area blackens over the life of the lamp thus creating unsightly dark areas and uneven lighting effects.’ Fluorescent lamps are sometimes offered in a small selection of colours, through the use of a coloured sleeve. Wolstemholme feels this is relatively ineffective as it significantly reduces light output. Cold cathode however offers a wide selection of vivid, saturated colours created through the use of a phosphor coating on the inside of the tube.


‘Whilst we accept that the initial outlay for a cold cathode system may be more


than fluorescent, the significant product and service benefits are clear to see. A better product, which is quicker and easier to install is provided and there are significant lifetime benefits with a cold cathode system.’ Electro Signs has completed an installation in the new Shoe Galleries at Selfridges in London. The piece was the brain child of Allanah Weston, creative director of Selfridges and her team. The idea came from the Sistine Chapel in


Venice but with a hint of fun; painting with cold cathode was the request. The piece comprises 400 various shaped and patterned tubes in the form of cherubs, banging nails with hammers, holding sticking plasters for sore feet, pouring water in a bowl to soak your feet and tying shoe laces. The strap line was ‘What’s your shoe story’, and the job was completed within just four weeks. The piece measures 9.5m x 4m, and it was suspended from the ceiling. To make the oval ring in keeping with the overall scheme, laser cut acrylic letters were applied to the piece with words ‘click clack stomp snap’.


‘The cold cathode tubing was made in compound three dimensional shapes and

fitted onto an oval fabricated tubular system,’ explains Chris Bracey from Electro Signs. ‘The high tension cables were braded in specially woven dove grey weave to reflect the different coloured tubes. Each cherub had six wings, which were wired onto a three channel animator to give the effect of flight. The cold cathode tubing was mounted onto laser cut acrylic shapes, which made assembly easier.’


Cold cathode still has a firm foot within the lighting arena, and will continue to do so, offering long lamp life, flexibility, and the ability to withstand varying temperatures.
