German quality Spectralux lamps can outlast nearly all competitor brands simply because they are made better. Special phosphor coatings within the lamp ensure brightness is maintained throughout their rated life of 20,000 hours. In fact Spectralux, when measured lost only 12% of their brightness over 20,000 hours. This means that unlike inferior lamps Spectralux won’t go dull 6 or 12 months after purchase. All Spectralux tubes comply to AS/NZS 4782.1 and AS/NZS 4782.2
CHART SHOWS LUMEN (LIGHT) DEPRECIATION UP TO 20,000 HOURS
Lumen depreciation simply means the amount of light loss a tube suffers over time. Spectralux tubes retain their brightness long after most other tubes have gone dull.
