12 volt outside light recommendations.

Hi, back again. So it looks like you were all correct and that 240 volt lights are needed. As the lights are going to be mounted on the wall, is there a box (stand off bracket) I can mount on the wall which has a bottom access recess for the cable and then go into the back of the light rather than chasing into wall etc. All I can find are corner mounting brackets but none for flat walls. Heard of besa boxes but I have looked into them and they seem to be for trunking and the fixing holes on the front seem to be offset.


Thank you all

Do you have a style of light fitting in mind yet - a picture being 1K words and all that -  not all are suitable for the BESA box and other box designs often have a large stand-off distance.

Or can put the wiring and the lights on opposite sides - unless the opposite side is next door I suppose.. - a lot of wall light designs have knock out holes to allow the cable to come in from the side or bottom of the fitting anyway, no back box needed then.


Not sure the mental picture of what you want to do is really quite understood.

Hi. Thanks for your reply. These are basically the lights I want installed. I have put25mm trunking in the ground and want to attach  3 of these to wall in the gravel drive. I don't want to go into the lightfrom the back as that would mean chasing the brick wall. So I want to stand it off the wall to be able together cables in the back and loop into the next light. I don't really want to mount a piece of timber off the wall to be able to run the cable behind and into the back of light.


Thank you

I did think of the corner bracket and just bending the ends to a 90 degree but at 17 quid a pop it is expensive. Then the flood light bracket but not sure that would work as bolts would be needed and probably ruin the integrity of the ip rating. Screenshot_20210107-120448_Chrome.jpg

BESA boxes are for conduit, rather than trunking, and thus are compatible with 20mm (or 25mm) threaded fittings e.g. cable glands. The "U" shape ones (with two entries, both pointing downwards) usually have the screw lugs horizontal too. If you're googling then then they're perhaps more often listed under "conduit boxes".

Hi, thanks so much for your reply. 


I have used 25mm corrugated plastic conduit. I think you can put glands on this? I don't really wan't to run the conduit upto the light. I have been told to use hi-tuf cable for this run as it is buried in the conduit and just a couple of inches showing in and out of the light fitting for sparky to wire up.  I shall look into the conduit box now.


Thanks

Amazing. This is the kind of thing I was looking for.

Yes, you can put glands on 25mm flexible conduit ... although they'd normally have 25mm threads, rather than 20mm.


Generally cables buried in the ground need an earthed metallic armour or earthed metallic sheath - to ensure safety if they're struck by digging tools. Unarmoured cables like HiTuf  aren't suitable for burial unless in a duct/conduit that offers an equivalent level of protection ... which I suspect a bit of plastic conduit isn't going to. The more usual approach is steel wire armoured cables, ducted underground if you prefer, glanded direct into the conduit boxes (using "outdoor" (CW) glands, not the cheaper indoor (BW) ones).  You'll also need a bit of care to ensure that the conduit box is weatherproof when installed - especially around the fixing holes and junction between the box and fitting.

here are the   fitting instructions for that up-down wall light 

Looks like rear entry it is.


you can use those boxes with soft cables as well, with compression glands   but you do need to be careful to get the right thread and the right  cable size though, there are a lot of options.
