Specifications: Condition: 100% Brand New Weight: 35-83g/1.2-2.9oz Power: 20-50W, 60W, 120W, 160W (optional) Application Range: Suitable for halogen lamps, with up to 6 20W bulbs; more than 6 require a higher-wattage transformer. Choosing an Electronic Transformer: 1. Choose the same transformer wattage as the original lamp. 2. Choose according to the total wattage of the total number of lamps. Package List: 1 x Electronic Transformer [How to Choose an Electronic Transformer]: 1. According to the wattage of the original lamp transformer, you can choose the same. (If the original is 160W, just buy 160W) 2. Choose according to the total wattage of the total number of lamp heads on the lamp (for example, the lamp bulbs on the lamp have 5 20W or 10 10W, so the total wattage of the total lamp bulbs is 100W, and the transformer is 105W; if you choose an 80W transformer: the transformer will shut down. The wattage of the transformer you just purchased is 5-20W higher than the total wattage of the lamp bulbs on the lamp, so the lifespan of the transformer and the lamp bulbs can be extended, and the brightness of the lamp bulbs should be brighter. Note: Choose if it is too large, the lamp bulbs will be a little darker! It is better to be only larger than 5-20W! Note: Input wire (red line) IN: 220-240V; Output wire (gray line and white line) OUT: 12V.
