Voltage provided to a luminaire by the power supply.

Cycles (frequency) per second.

The operating temperature of a light fitting indicates the safe temperature range in which it can be installed. Exceeding this range can reduce the lifespan. Adhering to specified temperatures ensures optimal performance and longevity.

Lumen Depreciation figures published refer to the L50, L70 or L80 classification system where the number relates to the percentage of light output. So a 30,000hr L70 LED would be expected to have 70% of its rated output at 30,000hrs. LED’s are subject to very small operating temperature parameters and figures quoted are typically at 25°C.
