Posted By Richard Hendry Good morning all, does anybody know if there are any regs regarding exposure to high lighting levels ? One of our technical team recently raised an issue after visiting a customer, where part of the customer process apparently uses between 10,000 and 20,000 lux of diffused white light from fluorescent tubes, or LEDs(Red ~620nm in this case). Any thoughts ? Richard.

Posted By Jeffrey Watt Richard Have carried a light meter from a warehouse into the open air and watched it go from 50 lux to 50,000 Lux on a clear afternoon. Quick google and a couple of sources tell me that light levels can reach 80,000 lux by noon (not sure where). I suppose this depends on if you need to stare at the light source, is it reflected or polarised light, what levels are at the eye during normal viewing, what the operators think, how long is exposure, what is the frequency and are there invisible high energy frequencies. The levels do not seem excessive compared to daylight. I await to be corrected by a'spert (B&Q slang for an expert). Jeff

Posted By Kevin Drum Sorry Richard just read post again and see you were asking about exposure times not Lux levels. Put it down to the fact I am going on leave in 2 hrs for first time this year sorry

Posted By Descarte Wasnt there recently guidance by the HSE on projectors due to the high intensity light which they use. http://www.hse.gov.uk/ra...ionising/whiteboards.htm I guess its not an answer to your question but does show an example of where high power non ionising radiation is seen as a H+S issue. Again only if looking directly in to the light source, as previously mentioned, although you could have issues of reflecting surfaces etc... Des

Posted By Richard Hendry Thanks all, I'll talk to the technician again now based on your comments, and if the issue is just glare or discomfort for short periods I'll look at getting him some tinted safety specs for use when on this specific task. I'll also look into the directive as suggested. Thanks, Rich.
