Think of fluorescent lighting, especially in an office, and your first thought will probably be of harsh strip lighting, flickering slightly, and with a faint buzz that\u2019s almost outside the range of hearing, but not far enough so that it doesn\u2019t irritate. While that fluorescent buzz and flicker is great if you\u2019re Michael Mann, and are looking for atmospheric urban effects for your latest film, they\u2019re not so good if you have to live with them every day while you work.<\/p>\n\n\n\n

Flicker no more!<\/h2>\n\n\n\n

You don\u2019t need to put up with that flicker and buzz any more, as high frequency lighting produces strong, steady light that doesn\u2019t visibly flicker, and eliminates hum and buzz completely within the human aural range.<\/p>\n\n\n\n

High achievers<\/h2>\n\n\n\n

High frequency lighting achieves these results by doing exactly what it says on the box \u2013 increasing the frequency of the electric charge to the tube. Standard fluorescent lighting operates at a frequency of around 50-60Hz, while high frequency lighting boosts that to 30 KHz. As well as reducing flicker and hum, this also increases light output, and that\u2019s not all. They also start up much more quickly, offering full light output within one second \u2013 no more hanging about waiting for the light to get bright enough to be able to do anything.<\/p>\n\n\n\n

No added expense<\/h2>\n\n\n\n

You might think that all these benefits come at a much increased energy cost, but you\u2019d be wrong. High frequency lighting actually improves energy efficiency by about 10%. They also maintain peak light output for longer than a standard fluorescent tube, and have a longer life-expectancy, so they more than cover the initial outlay involved in fitting them.<\/p>\n\n\n\n

Less symptoms<\/h2>\n\n\n\n

There are potential benefits for the many people who find that they suffer from headaches and eyestrain if they spend a great deal of time under fluorescent lighting at work or school, particularly migraine sufferers. Published studies have shown that under high frequency lighting reported symptoms of headaches and eyestrain were more than halved, and that people were more likely to use the lighting when conditions required it. As well as making users happy, switching to high frequency lighting could also improve efficiency and reduce sick days.<\/p>\n\n\n\n

Options<\/h2>\n\n\n\n

Since the introduction of LED, problem with flickering have become less and less common. When replacing standard switch-start fluorescent lighting, we would recommend strip lights<\/a> and recessed light fittings<\/a> in offices and corridors . Stylish external lighting can also be fitted thanks to  brick lights<\/a>, which look absolutely stunning alongside a swimming pool, garden path or in a car port, among many other uses.<\/p>\n\n\n\n

There are a number of options if you want to fit lighting that won\u2019t annoy users with noise and flicker, and will also save you money if continuous use is required. These include emergency recessed fittings<\/a>, golf bulkhead fittings<\/a> and low energy bulkhead fittings<\/a>, which are ideal for stairwells and walkways.<\/p>\n\n\n\n
