Outdoor pendant lamp - Ip rated lamp holder?

[rossyl]

Hi,

My wife purchased a rickety looking old light to go in our porch. Our porch is open to the elements - wind and rain, if travelling in the right direction.

The wiring on this lamp is atrocious and I wouldn't want to connect it up. I therefore want to renew everything.

Do I need to use an IP Rated lamp holder? If so, where can I buy one from, as the only one I can find is this (https://www.essentialsupplies.co.uk/waterproof-pendant-lampholder-es-10m-ip44.html)

Also, is there any issue with using a standard ceiling rose, as again, I cannot find IP rated ones.

Thanks very much.

FYI - The outdoor lamp is perforated steel. So lots of little holes. Which means, it is possible, the bulb inside could get wet.

That lamp holder appears to be the type that is IP44 only when the lamp fitted is a golf ball or similar. It appears to rely on the rubber skirt fitting tightly against the glass of the lamp to make a water tight seal.

the other question is what will he do with the remaining 9.7m of cable?

Isn't that the case for all lampholders ? Can't see any BC or ES lampholder being IP44 without a lamp installed in it Even then it's "debatable" since heating/cooling and changes in atmospheric pressure will draw water up past the seal (unless it's a very good seal) which is what I've observed with my outside lights.

I’m wondering if the IP44 refers to wetness spraying upwards towards the lamp.
The OP’s issue may be the cable entry at the top of the lamp holder.

I mean, an IP65 rated downlight is only rated for the underside. You can’t go up in the loft and drop a gallon of water into the top.

IP65 is protection from jetting water in all directions.

When they are mounted in a ceiling and installed in accordance with the MI, then yes. IP66.
But as a unit I don’t think so. These are IP66 rated.

But the terminal block and the driver circuits are not IP66.

There is a problem with IPx4. While it is protected against splashing, so you'd think it would be OK to be splashed - the spec for the test only requires a short duration. So something that's not what we might consider splashproof might pass simply because it takes longer than teh 5 or 10 minutes (can't remember offhand) required for the test.
