The lamps used in the Dedolight system offer four, distinct advantages. The small size of the filament contributes to the effectiveness of the optical system. Dedolight lamps cost only a fraction of lamps used in standard voltage lights with similar output. The long lifetime (especially of the 12V system) adds further to the savings in operating costs. The savings surpass the original purchase price of the entire Dedolight lighthead several times. The high durability of the lamps allow Dedolights to be used in tough environments. High shock and vibration resistance (especially with the 12V system) allows the use of Dedolights under conditions which would be practically impossible for fixtures operating on standard voltages.
