Anyone used these? http://www.lightfittingsuk.co.uk/Microwave-Sensor-Version-of-RadiaLED-Utility-Mains-IP65-282mm-Emergency-Bulkhead-23W-Integral-LED-Wh-Opal_A17VTG.aspx I'm planning to use these as main / emergency lighting on the stairwell of some flats I'm developing. I previously posted...

OMG!!! talk about perdantic! are you related to my wife?!, If resistance is proportional to 'kelvin, then the difference would be ~2'k = 1/150th, why am I even replying to this!!!

Ahhhhh, this is the sort of answer I need, makes a lot of sense, thank you

maybe it's a regional thing but I've never come across a cartridge fuse board round here

The system has been specified by the builing control officer such that there is a linked smoke detector on each landing, linked to a heat detector inside the door of each flat, each flat has a separate smoke detector system

Quote: What's the problem if the key switch disables the non emergency lighting if the stairs and landing are naturally lit during the day? or is it simply a regulation thing?. It's just poor design, and there's no need for it to be like that. What if someone turns the keyswitch off to...

The majority of wylex rewireable consumer units are not rated to accept a 40A device. there are other things to be considered and a qualified electrician would need to confirm the site condidtions are ok for the above solution. Read more...

If its a Wylex wired board you can get a 40A plug in mcb and fit an inline RCD in the cable leading to the shower, as long as the cable does not lead through insulation and it can freely lose heat to air or surrounding masonry then it should be ok for 8.5 kw, there are other things to be...

I was figuring on buying luminaires with built in sensors so no need for switched live in wiring. What's the problem if the key switch disables the non emergency lighting if the stairs and landing are naturally lit during the day? or is it simply a regulation thing?. Here's another one, If...

Thanks Bernard, I was put onto the microwave? switched lighting by the guy at CEF which will essentially pick up any movement in the space, whether it is in line of sight of the detector or not. just read the advice document from the fire authorities and simply timed switches are not advised as...

If you look up the latent heat capacity of water, it is very high compared to many other liquids, so 100kg water at 100'c holds more heat than the same amount of oil at much higher temperatures. I fitted a system based on two 350 litre copper tanks encased in a 100mm thick kingspan box heated...

Hi Guys, although I've spent some years as a domestic installer mainly fitting showers and some domestic rewires, I now need to wire some emergency lighting in some flats that I have bought, but now am realising there is more to it than I initially thought. My initial thoughts were to have...

Bottom line is that both sytems have advantages and disadvantages, the right system will depend upon the design of the building, who is using it and their lifestyle

If there's just one or two of you in the house then a combi is ok but they're rubbish in a family home when more than one hot water outlet is likely to be turned on, I've had two combis, the last was a 35kw w'bosch, the shower would stop altogether if anyone turned another hot tap on and it took...

Thanks for the replies, I will see what they go for on Wednesday
