Abstract
The invention relates to the supply of lamps ('″) of at least two different lamp types, of which a first lamp type (′″) has a wattage which is approximately a whole multiple of the wattage of a second lamp type (″), whereby the same ballast devices () are used, embodied for the direct supply of the second lamp type (″) and which may be operated in parallel for the supply of the first lamp type (′″). The correct connection of a suitable lamp (′″) to the ballast device () is monitored by means of a signal exchange between ballast device () and lamps (′″) before switching on the supply line of the ballast device ().
