No, the LED (light emitting diode) is a solid state device that does not "burn out". However, LEDs do get dimmer as they age. If left on continuously, the LED will start to dim after 10 years. The LED will not break in normal use.
IP means “Ingress Protection” or “International Protection”. The IP code is defined in standards IEC 60529&DIN 40050. It classifies the degree of protection provided by an electrical equipment enclosure against the intrusion of solid objects & liquids.
All our work light designs are exposed to extensive testing before being approved. These tests include: Lumen output & light distribution, vibration and shock, dust & humidity, exposure to heat & cold, thermal cycling, thermal protection, electromagnetic compatibility, full functionality, abnormal conditions, chemical resistance, & usability.
Before delivery, every single production lamp is subjected to full functional testing and is also operated for a minimum of 10 hours to ensure any possible early life faults are identified.
