Pool light upgrade

[tbarut]

Transformer :
Cat# T111863
Primary volts: 120x240
Secondary volts 12x24
1.0kVA 60HZ 1 phase

Led lights:
Spectrum 360
12v ac 30va

Would this transformer be efficient for this bulb specs? If so how much lights can I put on each transformer?

If you were to load it up at 80% you can have 26 of those lights.

Welcome to TFP.

That is not a listed pool light transformer that meets NEC 680 and is not safe to use for pool lights.

Yes, welcome to TFP! While I ordinarily admire & respect the DIY mentality, yours is a case where I strongly encourage you to please hire a licensed electrician for the job, someone who should also recognize that transformer is not listed for pool/spa use. There are so many ways to miswire or misconfigure such a transformer that getting a professional might one day save a life. If not today or tomorrow, ten years from now when a simple mistake turns into an unintended but deadly scenario. As others have noted in various threads here, run a quick web search "man dies from faulty pool light" to read about many examples.
