Why do I have trouble dimming my Phillips Masterline™ lamps?
These lamps contain a diode which may interfere with proper dimming performance. Lutron Electronics does not recommend dimming these lamps. Diode lamps possess either negative or positive polarity, however, the lamps are not marked to indicate whether they are positive or negative. Unsatisfactory dimming performance can occur if the dioded lamps in a circuit have the same polarity (i.e., all positive or all negative). Under these conditions, the lamps will flicker and will not dim below approximately 50%. Lutron recommends that you try one of the following suggestions: • 1. Replace one lamp in the circuit with a lamp of opposite polarity. As long as there is at least one positive lamp and one negative lamp in the circuit, no problems will occur. Since the lamps are not marked as to their polarity, some trial and error may be required to find a combination of lamps that works properly. • 2. Use a dimmer with neutral connection, such as the Nova® low voltage series (NLV-600, NLV-1000, NL
