Hitachi Hi Grade Daylight Fluorescent Tubes

Japanese quality 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, when measured lost only 12% of their brightness over 20,000 hours. This means that unlike inferior lamps Hitachi tubes won’t go dull 6 or 12 months after purchase. All Hitachi tubes comply to AS/NZS 4782.1 and AS/NZS 4782.2
