Watchdog safety alert on LED light

October 26, 2010

PARENTS have been warned to keep young children away from areas lit by new-style light-emitting diode (LED) lights and to avoid toys that use the lamps.

Public health watchdog Anses has just completed first tests on the lights, which are starting to be increasingly used in many different applications, and says it found that some were not suitable for public use.

LED bulbs can last for 25 years and give out an intense blue-white light. They give the same illumination as a traditional incandescent lamp, but use only a tenth of the energy. They are starting to replace traditional lamps and a report in the Daily Mail said London’s Dorchester Hotel had cut its £150,000 lighting bill by a third since switching to LED lighting.

Now they are used as car running lights, billboards, kitchens and on TVs.

Anses tested nine types of LED lights against the IEC 62471 standards and rated three in the second-highest risk band.

It says the intense blue-white light is a “toxic stress” on the retina, with a severe dazzling risk. Youngsters are particularly sensitive to this risk as their eyes are still developing and the lens is not capable of filtering out the light wavelengths.

Anses that the intensity of LED lights should be reduced and public use restricted to lamps that give off the same intensity as traditional ones. High-intensity LED lamps should be for professional use only.

“LED lighting causes headaches in Dutch workers”

LED lighting causes headaches in Dutch workers

The 350 as environmentally friendly promoted LED lights installed in the Dutch town hall of Hoogeveen appear to cause headaches in the employees.

The lamps also produce vibrations on computer screens. “If your hand moves along a lamp, a stroboscope effect occurs in the office. Sometimes it seems like a disco in here” said town spokesman Hans Vonk.

Just this week the Dutch Environment Minister Cramer started a public campaign to persuade citizens to use energy saving lamps or LEDs. However, installation expert Nico Koreman warned for the risk of strain on the existing electricity network. The cause lies in certain electronics for the new lighting, which can manipulate power frequencies. “With very unpleasant effects such as by burning and melting equipment and flickering lights”, warns Koreman. “The frequencies are so high that you can’t detect them using standard measuring equipment.”

One solution is to avoid cheap electronics from the Far East, says Koreman. “And do not buy the cheapest light bulbs, but stuff from regular brands.” The town of Hoogeveen will replace all the lights with a newer generation of LED lamps, which have already been tried in three rooms. “These new lights do not seem to cause health problems,” said Vonk.
