I have a wide variety of Malibu Transformers. There are approximately 20 to choose from in all. The pricing varies. The 100w are 20, the larger 300w are $40-$60, depending on photo sensors. I have two large high capacity 600w for 80 each. Only a few are posted as images. They range from 100w to 600w capacities. Most with timers. Some with a photo cell to come on at dusk. Some used some brand new. All work great.
