A major factor in the perfect lighting is - beside the used lamps - the lamp, the bulb or fluorescent tube itself. Therefore, the GIESEMANN lights will be always supplied already including the optimal lamps (fluorescent tubes, bulbs etc.) in original OEM quality. First and foremost, we equip our lights with the original Giesemann MEGACHROME metal halide bulbs and the new GIESEMANN T-5 fluorescent lamps. All our lighting products have an excellent reputation worldwide.
