Question 1: What does IP (Ingress Protection) Class mean?

IP Class is a standard that was developed for rating the environmental protection provided by an electrical protection. IP Classification generally consists of 2 (or 3) numbers.

1)       Protection from solid objects and materials

2)       Protection from liquids

3)       Protection from mechanical impacts

For instance for a product at the protection level IP 23C, number 2 indicates the protection level from solid objects and number 3 indicates the protection level from liquids. Letter C indicates the protection type from mechanical impacts.

Question 2: Can the use of sensors in luminaries with LED and fluorescent lamps cause problems?

The use of sensors in luminaries with LED does not have any kind of a negative impact. However, the use of sensors in luminaries with fluorescent lamps is not suggested. Since the sensor would turn on and off the fluorescent lamp very frequently, this would shorten the life of the lamp.

Question 3: What is the difference between fluorescent lamps and LEDs in terms of energy efficiency and energy savings?

LEDs are on average 40%-50% more energy efficient compared to fluorescent lamps and they have a longer life as well.

Question 4: What are the conditions for using luminaries with LED efficiently?

LEDs should be used at the temperature and environmental conditions that are indicated on the product catalogue. Moreover, attention must be paid not to exceed operating current values.
