How to replace a pendant with recessed LEDs

[Generic Friend]

I'd like to replace a pendant light with recessed LEDs, but can't find a decent guide anywhere on the 'net. Can anyone point me to one, or outline the basic steps?

Assuming I want to move the pendant and replace with 4 LEDs, would the following be correct?:

1. Replace pendant ceiling rose with 4 way junction box (to include switch). Wire out to the first LED.
2. Wire into another 3 way junction box, wire out to the second LED
3. Repeat as appropriate

Am I missing anything?

If I need IP65 lighting for the bathroom, do the junction boxes need to be the same rating? I assume not if they are behind the ceiling plasterboard?

Yes, and no.

You don't need 4 junction boxes.

1. Junction box (if not in an accessible loft space, it must be maintenance free) 4-terminal
2. wire out to first fitting
3. wire from this fitting to the next and repeat.

You just use the connector on the light fitting instead of the 3 unnecessary JBs

This work may or may not be notifiable, see here

Thanks, do you mean just wire directly into the light fitting itself, or use an actual separate connector, if so what type?

Something like this? http://www.screwfix.com/p/wagobox-light-junction-box/8423f

Sorry, you're not the first -

Why are DIYers so mad keen on junction boxes?

 

[Iggifer]

1. Yes, there is space in the supplied connectors for two twin and earth cables
2. You can use a wagobox, but as you have to buy the Wagos separately, it'll work out cheaper to get one of these

Interesting link. That product is described as "maintenance free" but it has screw terminals

 

[EFLImpudence]

Interesting indeed - They are not MF.

Quite so. I also can't help but wonder what feature(s) of it qualify it as a "17th Edition" JB?

Kind Regards, John

Cable restraints ???

Yes, I wondered about that (can't think of anything else!), but was there not a requirement for cable restraint prior to the 17th Ed.?

Kind Regards, John

They are relatively recent. I can't remember exactly when required.

They are relatively recent. I can't remember exactly when required.

I realise that those JBs (or virtually any with built-in cable restraint) are relatively recent, but I was talking about the concept of restraint for cables entering JBs (previously usually provided external to the {fixed} JB). Did that requirement not pre-date the 17th ed.?

Kind Regards, John

 

[Iggifer]

Oooops. Apologies. Didn't read the link properly (or look at the picture apparently)

 

[sparkwright]

Those junction boxes in the link were intended for downlighter wiring, probably before the 17th Edition.

Some goon has wrongly described them as 17th Edition maintenance free ones.

If you don't feel confident to replace light fittings, there are also plug in LED lamps, styled to look like traditional GLS lamps, that swap straight into the light socket, ideal for Rented Properties, where you can't just change the Landlords light fittings, but want the economic running cost of the LED lamps.
