HPI-T stands for high light output and ensures a pleasant atmosphere. Notes: Even during tests, only use in a completely closed luminaire (IEC 61167, IEC 62035, IEC 60598). If a lamp breaks, the luminaire must be able to absorb the hot lamp parts. For use with a ballast designed for high-pressure mercury vapor lamps. 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.
