Need this Dabmar Open Face Outdoor Step Light – DM-LV709 but 7.75″ L and 4.75″ H that will hold up outside. How much is the transformer since I will need 2 and 8 lights?
Answer: To calculate the transformer required. For example, this outdoor step light from Dabmar (the manufacturer) uses 20W lamps, and to power 8 pcs of DM-LV-709, it would be 20W x 8 = 160 watts required to power all 8 fixtures. So the transformer needs be at least 160W or greater. In this example, we would recommend this Dabmar Landscape Lighting Magnetic Transformer with Photocell and Timer – 300W, 500W – DM-LVT-I.
