swiming pool lights?

[roboze]

Hi all,

Got a job to do on a swimming pool, looking at the regs, i would say that all lights in zone 1 have to 25v ac or under (12v). do you guys agree?
and the 230v connection has to be outside zonew 0,1 and 2.

If so, does anyone know where i can get 12v wall lights that take separate transformers.

as i am struggling to find any.

Cheers

Rob

I've found this, don't know if it helps but the seem to know what their on about.

Swimming Pool Lighting, Above Ground Pool Lights & Underwater Lighting

Double post.

For in-pool underwater lighting you need 12 volt ''Wet Niche'' fittings. They come in 100W and 300W sizes. The transformers need to be sized at 150W or 350W respectfully.

Normally you would buy an off the shelf swimming pool control panel, that would incorporate everything you need for the auto/manual control of the pool pump and the in-pool lighting. Just give the supplier the size and ratings of the pump and lighting. If you get the basic set-up panel, you can then add further controls and protection for pool surround lighting etc, yourself...

Make sure that you bond the steel re-bar of the pool with any and all external accessories such as pool ladders etc.... I would normally also connect to a ground rod too for testing purposes....

If you need any more information on pool installations just ask ....

One more thing you need to remember, when wiring for these underwater lighting points, ''Remember that these lamps are 12 volt'' A 300W lamp will need a cable size capable of taking 25A and any volt drop incurred from the control panel to the lamp. A 100W lamp will need a cable sized for say around 9A and any volt drop considerations... I normally use standard SWA or the more flexible SWA cables. Armouring is just for the cable protection, and should not be earthed. The watertight glanding is normally supplied with the deck mounted connection box and will be part of the lighting fixture....
Connection to the control panel should be via non-metallic type glands...

hi Engineer54,

i was actually asking about lights in zone 1 though the OP was a bit vague!

any ideas?

You can always try Plastica

They do a number of kits.

Underwater lighting must be 12V - and usually 300W - most pool light units are PAR56, either conventional lamp or more usually LED based these days which have far lower current consumptions.

They are also mostly pre-wired and semi-sealed - you take the flying lead out to a deck box for making your joint and put the transformer in the pool house.

The defacto norm is to wire all poolside lighting in SWA. For 12V conventional wiring 6mm 2 core SWA should be sufficient.

They do a range of poolside lighting too which is ABOVE ground - similar rules apply - swimming pools are also treated as a special location for zoning, etc. Any sockets placed remotely close to the pool area should be RCD protected at the socket too.

I have used many types of perimeter lighting fixtures. Basically any type of non-metallic fixture with a suitable IP rating can be used. Obviously needs to be 12 volt, but then most fixtures can be converted to this voltage. Depends what type of light fixtures your client wants, low bollard, in deck, posts, etc....

Think you had better get a bit more information, as to what your client wants, before you start looking...

Using 6mm cable at 12 volts isn't going to get very far. It very much depends on the location of the control panel, and the distance from the control panel to the deck termination boxes. So maybe 6mm cable will be OK for one end of the pools light fixture, but the chances are, it won't be for the other end of the pool!!!
It doesn't take far, to lose a good bit of that 12 volts you started off with... It's not that uncommon to see 16mm cable being used in unfavourable circumstances...

Agreed.......

the end of that sentence got lost somewhere........should have read

".....For 12V conventional wiring 6mm 2 core SWA should be sufficient for up to 5m or so."

Thanks for pointing it out

Sorry roboze, didn't read your initial post too well... OK, your looking for wall lights, basically if there going to be mounted very close to the pool area they are going to have to comply with a decent IP rating as well as being 12 volt. As i stated before, most external light fittings can be converted quite easily to 12 volt operation, especially when the transformers are going to be located remote from the fitting. Basically check out all the manufactures web sites and maybe give a choice fittings and costings to the client for approval.

Just remember the supply cable from the transformer to light fitting will need to be sized accordingly. Frankly being wall lights i wouldn't worry too much about whether they are metallic or not with a 12 volt safety supply.
