Maintenance? New Orleans before (!) the hurricane
Lamp replacement in Germany: lamp replacement costs from 30,- € to 100,- € / light point Lamp replacement after 4 years instead of 3 years : cost reduction ~ 25 %
Lifetime of fluorescent lamps 1 T8 (26mm fluorescent lamps ) F4Y Luminous flux: F4Y36W/840 3200 lm F4Y58W/840 5000 lm For conventional ballast / 50Hz Lifetime: average lifetime > 24.000 hrs 5% failure after 16.000 hrs Lamp specially developed for conventioal ballast / low loss ballast, but also operation with electronic ballast possible
Lamp replacement in groups In outdoor lighting plants lamp replacement in groups is more cost effective than single replacement Lamp replacement in groups increases the security of the lighting plant and reduces the rate of disturbances, because the mean age of the lamps is reduced The rate of premature failure of lamps must be as low as possible to reduce the expensive single lamp replacement and to prolong the group replacement intervalls Costs: Lamp + Personnel Optimum group replacement interval: After 5 – 12 % premature failure acc. to cost structure of energy provider, but not more than 4 years Source: Philips lighting Time
