To satisfy the level and intensity of illumination three types of bulb are available.
Fluorescent lamps reduce loss of heat energy and operate on low wattage, thus saving energy and cutting running costs. Compared with a filament lamp of similar output, energy consumption is reduced by between 70% and 80%, and life expectancy is increased by over 600% (8000 hours).
Halogen lamps are fitted with three position switches to provide dual intensity.
LED lamps provide long life, good intensity and light distribution.
