12v lighting makes sense in an off grid situation where you are trying to save power as much as possible. You can avoid the inverter being on the whole time just to run the lights. But as mentioned it's primarily a bugger to find a standard wall switch rated for DC. I use a standard switch to do this for about 24 watts of12v led lights and it works OK (has been for about 3 years) , but I can tell that the switch is getting tired from all the arcing and is not as responsive as it should be.

Glad I'm not laybouring for you!

Thanks Dave I will indeed have a look at safe zones

With regards to wiring within a service void. What happens when the wire crosses a stud? you could leave a gap in the batten but it will need plating over with a metal protector will it not? (cables less than 50mm depth need protection IIRC) Or do you try and have only vertical drops? That's still a problem in a ceiling though... What do the sparkys do?

Commissioning of a UVC might mean signing it off, which he/she is not able to do. They are easy to install but you are required to be certified to do it.

Acetone is a good solvent for wet foam. You can get it quite cheaply from glass fiber roofing suppliers, as they use it for resin clean up. Good for nail varnish removal too

Some very useful info on this thread about slim LED downlights I bought a few of these from Ebay to test out but i am a bit concerned with the sticker on the back which says "do not use on the same circuit as fluorescent, halogen, HID light sources or extractor fans as they may create spikes which could damage the LED driver" The light and fitting design is great but is this warning a caveat for crap quality components? seems crazy to have a driver which can be damaged by other lights on the circuit. That's basically useless IMHO Anyone else seen this? or have an opinion? Mike

Hi folks. I'm not quite sure if this is the correct section of the forum for this, but there are sooooo many sections ! I stumbled upon this air tightness testing and sealing system on YouTube and thought it worth a mention here.. http://aerobarrier.net/ It's an American system of sealing gaps in a new build using a high pressure door blower set up and an aerosol sealant which is misted into the rooms. The sealant migrates to gaps in the building fabric and seals them up. Allegedly.... I thought it was a novel approach to air tightness testing anyway Any thoughts from the forum? Mike

This company supply screw piles and have a fair bit of information on their website if you are interested. https://www.hubbell.com/chancefoundationsolutions/en/about-us/chance-products/helical-piles I have no affiliation to them but I have used their screw piles for anchoring a mast. Smaller piles can be installed using a hydraulic motor attached to the end of a long lever running of a small hydraulic power pack, so installation might be easy.
