lampliv

Lampliv is a term used in the lighting industry to describe the predicted operational life and performance of a lamp or luminaire. It covers how long the light source remains functional, the level of brightness it maintains, and the stability of its color under typical use. The concept is applied across consumer, commercial, and industrial lighting to compare products from design and sustainability perspectives.

In practice lampliv is quantified with metrics such as rated life hours, lumen maintenance, color stability, and failure rate. Commonly reported figures include the expected hours before failure or before light output falls below a defined threshold (for example, L70 or similar benchmarks), as well as changes in color temperature and color rendering index over time.

Factors that influence lampliv include thermal management, operating current or voltage, switching cycles, ambient temperature, humidity, and mechanical stress. Poor heat dissipation, excessive electrical stress, and harsh environments accelerate lumen depreciation and color shifts, reducing usable life.

For buyers and planners, lampliv informs maintenance schedules, replacement planning, energy efficiency calculations, and total cost of ownership. It also guides design decisions, such as choosing materials, phosphors, drivers, and cooling strategies to maximize long-term performance while meeting regulatory and sustainability goals.
