We purchased a foreclosed home with a pool and are trying to get the pool lights operational without breaking the bank. They are 12 volt Hayward E39338 fixtures. One is an R40 fixture in the end of the pool itself and the other is a R20 fixture in the spa. The R40 has a 300 watt bulb and the R20 has a 100 watt bulb. Both are halogen bulbs.
A single feed wire runs from near the pool equipment on the corner of the house to a junction box near the R40 fixture at the pool. The spa light feed runs from the R40 (pool) fixture over to a junction box near the R20 fixture at the spa, so power is daisy-chained from one fixture to another.
My question is, what transformer do I use to make sure I have an adequate power source for both the 300 watt and 100 watt fixtures? Remember, I only have ONE feed from the house to the fixtures, so I cannot use a dual transformer model.
Thanks in advance
