An internal light for commercial vehicles which, it is claimed, gives greatly increased illumination over other types with less drain on the battery has been developed by Bardic Systems Ltd. It is suitable, for example, for use in delivery vehicles, ambulances, fire appliances, travelling libraries and shops.
Increasing demands on vehicle batteries represent a major problem for c.v, operators who often have to fit ancillary batteries or special generators. The benefits of more light on less power in these cases are obvious.
Improved efficiency is achieved by replacing tungsten filaments with a fluorescent strip and transistorized inverter operating at a frequency well above the audible range.
Two versions are available— for 12 or 24V operation. A battery drain of less than +amp is claimed, with the lamps giving five to six times the illumination obtainable from tungsten lamps of similar Wattage.
The lighting units can be either surface or flush mounted and their slim line provides maximum headroom. A special diffuser ensures full light in working areas.
