SON H as a replacement lamp for mercury vapor lampsNotes: For use with a ballast designed for high pressure mercury vapor lamps. For outdoor use only. It is very unlikely that the glass breakage of a lamp will have a negative impact on your health. If glass does break, ventilate the room for 30 minutes and remove the splinters using gloves if possible. Place the splinters in a sealable plastic bag and take them to the recycling center for recycling. Do not use a vacuum cleaner.
