Long-life lights
Fluorescent tubes claimed to last three times as long as conventional models and consume 10 per cent less energy have been developed in Sweden.
For 18 and 36 watt tubes, the service life is put at 27,000 hours, and for 58 watt tubes at 23,000 hours. The cost of changing tubes is a considerable part of total lighting costs, and in many industrial environments is even larger than the of the tube itself.
