A Kiwi manufacturer has rejected claims that energy-efficient light bulbs trigger crippling migraines.
The Migraine Action Association in Britain claimed that the energy-saving bulbs might trigger migraines because they are miniature versions of fluorescent strip lights, which are known to cause the condition.
The bulbs are gaining popularity because they consume about a quarter of the power used by traditional light bulbs.
Christchurch Company Energy Mad reported selling four million energy-efficient light bulbs in New Zealand during the past three years.
And, Chris Mardon, Managing director of Energy Mad, said that the bulbs did not cause headaches because modern fluorescent tubes did not flicker as much as cheaper, older tubes.
"Modern fluorescent lights flicker on and off thousands of times a second and so the human eye cannot perceive it. Some of the cheap and nasty stuff may still cause problems, but all the brands converted years ago. A modern bulb is basically no different from a normal light bulb," Stuff.co.nz quoted him, as saying.
Annette Hallam, New Zealand Migraine Sufferers' Support Group director, said that she would examine the claims.
"I would like to look into it. If it can help one or two people, then that is fantastic, but I would like to know more about it," she said.
