Hi.
I have a couple of dead Jandy Watercolor LEDS and when looking for options to change them out i was speaking to a guy who suggested that i should consider making the change to 12V LEDs. I've decided that while having has 120v on the pool lights for years has been safe - it cant hurt to convert to the 12v for extra safety.
I have a Jandy Aqualink controller.
At the moment - the pool lights are connected on one relay, the spa light is connected on another relay.
120v is fed from my GFCI to each relay and from the 1st relay - 120v is fed to the 2 pool lights, and from the other relay 120v is fed to my Spa light
I haven't pulled the relay off yet but im assuming its the standard 3 HP 24v dry contact..the 6581 relay
Couple of things i want to verify - if anyone is familiar with doing this.
I have the lights and transformer on order. 2 12V Jandy Pool Lights 1 Jandy Spa light
The pool guy recommended a J&J Halco transformer TR-300-PP rated to 300 Watts.
My question is more around the relays for the lights and if i need more than 1 transformer
As these are dry contacts - im assuming that i can use the existing relay for each light and instead of connecting the input of the relay to 120v - that i would simply connect it to the 12v coming form the transformer.
The wiring would then look like;
120v power from the GFCI to the transformer
- 12v from the transformer back to each relay
from relay 1...power both 12v pool lights
from relay 2..power the spa light.
The lights don't draw any more power than the 120v but there is higher current at lower voltages and i don't know if there is a specific 12v relay im supposed to use
that is rated for higher current
Alternatively...i could send 120V GFCI power to the relay.
- from the relay 120v would go to the transformer
- then from the transformer - the 12v would go to the lights.
In this scenario - the transformer wouldn't be powered all of the time but i'd need 2 transformers ( one for the pool lights, one for the spa light)
it does take away my concern however about using the relay with 12v across the relay as this way feeds 120v to the relay.
The other question is the transformer. The guy inly suggested i needed one ( at the same time i was ordering 3 lights) but i really never asked if i needed more.
I cant really tell for the manual how many watts each of these draw. I did find this however..
A separate 12-Volt AC Transformer is required on all 12-Volt Models. For Jandy WaterColors Light use a 150-watt multi-tap 12-volt system per light.
NOTE For optimum performance Jandy recommends to use one transformer per 12-volt light.
So...do i take a chance and run 2 lights off a single 300w transformer and the spa light off a separate transformer?
Fun Fun
Oh and im upgrading to an iAqualink at the same time with an IQ 30-RS
Appreciate any thoughts
Cheers
