MASTER PL-R Eco stands for maximum efficiency. Its six parallel tubes are equipped with the innovative 'Twist and Lock' base. The bridge technology developed by Philips ensures optimal performance with more light and higher efficiency at high temperatures in the luminaire. Notes: The photometric and electrical properties of the lamp are influenced by the operating conditions such as the ambient temperature and the operating position as well as the HF ballast used. Frequent switching and insufficiently preheated electrodes shorten the life of the lamp. 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 hand them in at the recycling center for recycling. Do not use a vacuum cleaner.
