Recess Light Draught Excluder Sock

What is it?

This is a draught excluding sock that folds around the body of a recess ceiling light fitting

Why do you need it?

Typically, when a recessed light is installed into a ceiling, a hole is cut which is much wider than the diameter of the actual light casing. If the exact size hole was cut, the light would not actually fit because it has external clips which need to be folded back to allow the light to be secured into place, which effectively increases its diameter.

For example

A light casing of 55mm diameter could have a ~70mm hole drilled into the ceiling. This is fine because the trim of the recessed light has a diameter of around 80-90mm, so when the light is installed, it appears to be a snug fit up against the ceiling.  

In reality, just above that rim is a gap of ~8mm ( 70mm-55mm /2 ) around the light casing.  Typically the light clips pull the light fitting up against the ceiling, however oftentimes these clips are not up to the job and over time the recessed lights drop out slightly from the ceiling hole.  This reveals a gap and can allow a draught to enter your room, especially if the ceiling has a cold loft space above it.

You may feel a very noticeable draught as the 'chimney effect' of the hot air escaping through these gaps causes colder air to be drawn in from additional gaps, such as other light fittings, skirting board joints and window frames.  

The Air Change Per Hour (ACH) can rise from the recommended 0.3 times per hour to a much higher 2 or 3 times per hour- effectively this means the hot air is escaping from your room at a much faster rate, and cooling it down.  

This may not seem like a big deal, but if you have several recessed lights in your home, it can become a big issue for your fuel bill, especially in  colder months when the weather can drop to much lower temperatures.  Cold draughts will equate to very high energy bills as your central heating fights to keep the room warm

The Solution

To fix this draughty issue you will need to block all of the offending gaps

Theses draught excluding Socks will solve the problem for at least the recessed lights

Print them in a soft TPU, turn off the electrical feed to your lights from the main consumer unit (do not simply just turn off the light switch in the room, pull down the recessed light casing, unfold the sock and slip it around the casing and push it back into place.  A slight rocking motions may help it secure into place

The Socks are designed to slightly compress and give just enough tolerance to allow the light fitting to securely fit back into place with zero gaps being exposed - depending on you light fitting size, you made need to scale the dimensions in your slicer to achieve a better fit

Dimensions

Internal Diameter = 56mm

External Diameter = 72mm

Important

Some recessed light casings can generate high temperatures.  I do not recommend using these Socks on a recessed light fitting that generates excessive heat. If you are unsure please seek advice from a qualified electrician before installing them

Do you know what a Boost Token is?
 

If you download models from MakerWorld.com it is likely that you've got some boost tokens in your account

They are awarded for completing certain tasks, such as downloading a model

It's likely that you have quite a few, but may not be aware of them

Tokens typically have an expiry date and many ppl do let them expire and don't use them - its a shame, but they're easy to overlook ;)

When you see a ‘Boost Me’ section, like the one below and click it, you will be able to gift a creator a boost of points, you can boost several times too

After a period of time these build up and the grateful receiver can exchange them for a growing list of rewards, such as filament, maker kits and more
 

Its a great way to say thank you!
