    Need to illuminate staircase steps by fitting LED luminares under the step behind a plinth/pelmet which been put on the step of an open tread stairs to close gap to 100 mm. Ideally a strip LED, got 20 mm recess to conceal it . Could do with auto switching i.e as someone gets on staircase light come on and when step off go off but not essential. Anyone done such job and can suggest make so many variants around?

    Weve got leds set into one of the strings with an led for each step. I routered a slot in the top of the string to carry a 2 core cable and the spindle baserail covers the cable/slot. Drilled a hole in the side of the string for each led and a smaller hole from the cable slot to the back of the led hole to carry the leds integral cable. Soldered each leds cable to the 2 core cable and connected the PSU to the 2 core cable.

    I used a kit of plinth/skirting leds that I think screwfix sell?? Light the treads beautifully without causing any glare or excess light in the room they run out of😁

    Ours are manually switched but you could rig a PIR to auto switch the power to the PSU.

    Had some more searching came across this.


    Looks really neat but at close to £700 for the kit will look for further examples.

    Compared to the Screwfix ones looks v dear but a lot of the cost is in the control unit. Will need to decide what level of sophistication I need.

    If you are ok to DIY it, buy this type of holder for the LED tape...


    Buy enough length of LED tape (choose the right "warmth" colour and the number of LED's per meter and brightness). Cut the tape to required lengths, say 900mm per tread, and solder the tape to 2 core tails (daisy chained), run up the stringer similar Philedge above. Check the transformer power required versus your choice of LED tape. Might need to go for 2 transformers, as something sticks in my mind about a limit to the length of tape you can feed (maybe a max current the LED's can see??). Can't recall exactly. I did this a few years ago for the underside of kitchen work surfaces.

    Ceiling/wall mounted occupancy sensors (foot and head of stair) can do the switching. Discrete unit like this maybe??


    Bet you could buy all the bits for £150.

    Plug connectors from eBay if you don't want to solder

    RGB tape if you want cool white in the daytime and warm white in the evening (or disco colours at Xmas)

    You do know you can cut off the garbage after the amazon product identifier and the google tracking from the cef link?

    I do now :bigsmile: though at what point it can be cut doesn't seem obvious, or worth the effort.

    Amazon can be cut after the product ID - www.amazon etc product-description product-id garbage
    Anything can be cut before a google ID and usually right back to the query whatever.com whatever ?gclid=garbage

    As to why, well apart from making things neater, it helps fight google's tracking at least a little bit.
    Or even shorter

    But hardly worth it
    Back to the OP: I think it's worth buying a few different reels of LED tape and choosing which one gives the quality of light that you like best in that location.

    Many thanks for the inputs challenge now will be to find stuff not made in China. Over last 2 weeks 2 fairly new LED floods have given up and one was inside a shed so no weather to attack it. I seem to be replacing my floods on a regular basis. 20000 hours life ?? it's a joke.
