220v to 12v AC wiring

But the LED is 12V AC?

It has a cup/seal on the back to keep water out from the connection

Cool man
Im just not sure what AC does in water if exposed.
I know DC is safe

Which is why 4x4's can cross rivers and not worry about shock

Adding a sonoff basic smart switch for the light.

I already replaced my old rotary timer with a sonoff basic connected to the pump. works great, and never have to worry about it going out of sync when there is loadshedding, etc

Nice. Also replaced my old rotary with a Sonoff POW -> can monitor the usage and power of the motor. It has saved my bacon once as I noticed when the pump wasn't going full force which meant something was wrong - got home and tossed the bloody temp-floater that got stuck in the weir!
 
Most of the pool lights can be removed from the swimming pool without draining the pool. It has 2 screws that you remove and then take out the whole globe and switch it over. If it is LED I wonder you can't just use the old downlight drivers. They put out 12V AC and 4amps. Much cheaper than the transformers they market for swimming pools

Educated guess here, but I think the 220v input is the blue, green and brown as they match with the colours of 220v sockets. The two reds are then positive and negative to the 12v light.

100%

Honestly if you don't know then you should rather let someone install it for you.
From the looks of it, 220v inputs: blue = neutral, brown = live, green/yellow = earth and red wires are 12v out -> check +/- polarity.

AC out does not have a polarity.

R499, cheapest I could find - https://www.takealot.com/swimming-p...0v-12v-125va/PLID71833676?gclsrc=ds&gclsrc=ds

Builders Express N1 City was R1999!!!!!

So your thread got me thinking to sort out my pool light myself. So walked into the local pool store and what do I find. EXACT same transformer as in your pic for R199. Got the light as well for R1000. Going to replce the light today and have my sparky do the transformer installation sometime later this week as well as adding a day night switch so the light is on all night.

R1000 for a light is insane. The light in my mother's pool is one from a Beetle and costs about R50 to replace. Also I would confirm the class rating on that transformer as that price is very low.

How do I check the class rating?

And R1000 for the light seems pretty cheap considering what places like Takealot and Builders charge for a LED pool light.

The class rating should be printed on the transformer itself. You need a class 2 I believe. You need to shop around for lights, those companies are more on the expensive side. Don't you have a fitting already installed thus just a globe replacement because else you need to drain a lot of water to fit a new fitting?

Will check on the class rating when I get home and report back.

With regard to the second part, yes I have a old halogen light already. So it has two housings. One housing is fixed to the swimming pool. The second housing contains the light and fits into the second housing that is fixed to the swimming pool. I havent removed the halogen housing yet, but assume you can just replace the bulb on it. But with LED's you replace the entire light fitting housing that fits into the housing that is fixed to the pool. Hope I am making sense here?

The halogen ones have a cover in front which one takes off then pull the lightbulb which is attached to a length of cable so one can do it above water, then pop it back and screw on the cover.

LED one can also be done above water as you simply remove the entire light housing and bring it above water, cut the cable, and connect (using the waterproof connector) the cable to the new LED housing and stick back in the water.

Good to know for next time.
 
Pictures below as promised.

Old unit out. Just two screws held it in place.Yes, water got in it with all the algae in the rain forest.

IMG-20210303-WA0013.jpg
Taken apart. Its basically three pieces The light unit is actually a sealed LED unit. I mistakenly thought my old light was halogen.

IMG-20210303-WA0010.jpg
Old bracket next to new light unit which is a one piece unit and not 3 separate pieces like the old unit. At the pool shop they the new unit should just clip in. That isn't true. Will have to drill two holes in it.

Closer look at the housing that is fixed to the pool.

I honestly dont know if this is adequate to waterproof the connection??

IMG-20210303-WA0007.jpg
This is the new waterproof connection bought from the pool place. Two top ampules get mixed with a power and paste is poured into the connection unit at the bottom.
