Waterproof junction box - who makes good quality ones?

[Rollerball]

I need to replace an old halogen floodlight but need to cut the current wire that exits via some brickwork and then connect that to the wire on the new LED floodlight.

So I need a waterproof junction box that will handle both the older grey 'rectangular profile' wire and the new black 'round profile' wire - looking on Ebay, Amazon, Screwfix, etc the boxes and connectors all look really cheap and nasty.

I also need it to have lugs/fittings so that I can screw it to the wall.

Who these days makes good quality junction boxes?

Ive found wiska ip rated jb’s to be good for external use.

Wiska 308 are the dogs danglies in these situations

But put the box over the point where the cable exits the wall, after drilling a 10mm hole in the back. Pack around the cable entry with compound: https://www.superlecdirect.com/r391-electrical-weathproof-compound-2x250g/ (At a push, silicone - but I don't like it!) to ensure its sealed against water ingress. Fit a stuffing gland: https://www.cef.co.uk/catalogue/products/1521720-20mm-ip68-gland-black into an entry on the lower surface to take the flex to to the lights.

Never rely on the entry membrane the boxes come with, and never enter through the top surface, also twin and earth cable should not be exposed outside

Any box you want and fill with re-enterble compound.

Wiska make a range of different profile inserts for stuffing glands. So you should be able to solve your “rectangular profile” issue.

Try and use the entry holes at the bottom.

And remember to drill a 5mm hole in the bottom.

Thanks for all of the helpful suggestions.

Think I'll use Wago connectors for the wires but having never used them before which ones should I go for?

Good advice - I have some WISKA 108 boxes for the SELV lights in the garden that have water collecting. I am waiting for the warmer weather to go out and drill holes in the bottom of the boxes. I had not expected ingress but the membrane seals are not 100%

I’ve never trusted membrane seals, for that reason n

I don't think I would for mains voltage. I will put a drain hole in and check what happens at the end of the year - I may end up with 308s and some glands
