Use only in totally enclosed luminaire, even during testing (IEC61167, IEC 62035, IEC60598)
The luminaire must be able to contain hot lamp parts if the lamp ruptures
A lamp breaking is extremely unlikely to have any impact on your health. If a lamp breaks, ventilate the room for 30 minutes and remove the parts, preferably with gloves. Put them in a sealed plastic bag and take it to your local waste facilities for recycling. Do not use a vacuum cleaner.
