Specification:Condition: 100% brand newWeight: 35-83g/1.2-2.9oz Power: 20-50W, 60W, 120W, 160W (Optional)Adaptation range: Suitable for halogen lamps, with up to 6 20W lamp beads, more than 6 need to be replaced with a higher wattage transformer.Selection method of electronic transformer:1. Choose the same transformer power according to the original lamp;2. Choose according to the total power of the total number of lamps.Package List:1 x Electronic TransformerHow to choose electronic transformer:1. According to the original lamp transformer power, you can choose the same. (If the original is 160W, just buy 160W)2. Choose according to the total power of the total number of lamp heads of the lamp, (for example, the lamp beads of the lamp have 5 20W or 10 10W, so the total wattage of the total lamp beads is 100W, and the transformer is 105W; if you choose 80W Transformer: The transformer will burn out. The power of the transformer just purchased is 5-20W greater than the total wattage of the lamp beads of the lamp, so that the service life of the transformer and lamp beads can be extended, and the brightness of the lamp beads should be brighter. Note: choose If it is too large, the lamp beads will be a little darker! It is better to be just larger than 5-20W!Note:Input line (red line) IN: 220-240V; Output line (gray line and white line)OUT: 12V..
