LED/SSL Light Sources and LED/SSL Luminaires: Lifetime and Lumen Maintenance

Designing with or specifying LED (also known as solid state lighting, SSL) luminaires is no different to any other luminaire. Depreciation and maintenance factors should be applied according to good lighting design practice and the appropriate application standard.

Designing with or specifying LED (SSL) luminaires is no different to any other luminaire. Depreciation and maintenance factors should be applied according to good lighting design practice and the appropriate application standard.

Despite the marketing claims of long life, LED lamps suffer a loss of light output over time just like any other light source.
Because of their long life, specifying the maintenance factors requires a slightly different approach but the fact remains any design or specification must include factors for losses.

Professional and responsible lighting designers should always follow best lighting practice; and provide practical and sensible information to the client and the general public at large.
