Fluorescent lamps are nice and useful, but unfortunately, without a starter unit they can, in general, not be dimmed. The CLS-T8 DMX Color changer is different. A dimmer is included, so that the radiance of the lamps can be reduced from 100 to 10 %. These tubes, that are more powerful than LEDs, are best installed as indirect lighting to put buildings on the spot. The illumiated Allianz Arena in Munich is a good example to show a possible effect of these lamps.
