    If you are in Pattaya I can give you details of a good shower screen fitter. HomePro suggested above didn't do custom build

    I am in bkk, what is the name?

    Every glass shop will be able to custom order it for you, you may not like the custom price. Every window shop will be able to make the frame, most will be able to custom order the glass. 

    one shop (grafinger) quoted me 8000 incl install and vat for 225by 35, is the price reasonable?

    No danger in trying it, it may work but be unpredictable and it's running the transformer outside its ratings.

     

    You can't just divide voltage amongst LEDs like you can normal lamps, LEDs are current driven not voltage and my not even start to conduct at less than 20V.

    tried it with 3, doesn't work. installed the adaptors the normal way a few days ago and they work flawlessly. Triac is thaaa besttttttt

    Your LED are current operated (not voltage). Your 7W LEDs are expecting a current of around 250mA which would develop about 20V across them. Setting your transformer to down, down, up (200mA) would probably be best, down, up, down (350mA) may over-drive the LEDs. In either case the transformer will max out at around 45V.

     

    Putting 3 LEDs in series at any of the available currents would likely be about 60V which is outside what the transformer says it can do, it may light the LEDs but behaviour under dimming could be unpredictable.

     

    thanks for your explanation, I thought that the 45v of the transformer would be divided by 3 leds (15v each) and making my Leds max out at around 5W each. Any dangers in trying it out?

    A TE-15 should be able to run two of your 7W down lights in series.

    The TE-15's finally arrived and I did a test run and they worked. I hooked up 2 leds on series on the transformer. Then I noticed the dip switches and I played around with it a bit. seems like the dip switch with three up (black means up) is the brightest on all levels and when switched 3 down is the dimmest on all levels, which suits my needs more.

    However, I wonder WHY it worked since the old (cheap) transformer that came with the leds were rated 18-23V, 240-280 mA, per led.

    Does this mean I can actually hook up 3 led lights in series and put it in the dipswitches in the down up down position?

    Hafele has some nice discounts

    I went to hafele design studio today and they have a nice sale going. A lot of the items you can find at https://www.hafelehome.co.th/
    However, not everything is listed, for example lights toilets, sinks and mirrors. If you like DIY'ing/home improvement take a look, I don't think you will regret!

    I myself picked up a knife set 700b, rinsing spray 499b, blender 1050b and a 90cm round mirror for 1600b. Pretty good for a branded item if you ask me. By the way does someone know if all of their products are made in germany?
     

    2 inch floordrain to pipe connection

    I suggest you get some 13.5 in the same size for practice and to create a forming tool. You can stretch the pipe to reduce the OD. You can then use that to stretch the pipe in the floor as long as it is not constricted. Alternatively have you checked the size of a straight junction as that may be even better.

    13.5? OD? what is that?
    A straight junction is a connector for pipes is it? Do you have a picture?

    The PVC will not crack if you use a paint stripping gun. A rubber coupling would work as long as you can get access to clean it, or change it. Rubber does not do well over here.

    You mean a heatgun? Does a torch works the same way?

    Having seen the picture. Does the metal fitting fit inside the plastic pipe? If so then it will not be difficult as silicone to seal the pipes will be enough. If it doesn’t that is more of a problem.

    Right now it does not fit, but uncleP said heat it up and stretch it. I saw in some youtube vids and it looks promising, dont know if its really that easy.

    Seems like they just put the drain on the pipe with tile cement around it. Which means to me it would be always possible to retrofit it the 'thai way', just trying to find something better. What would be the challenge of uncleP's way or the rubber coupling? Except for the pvc to crack while I try to enlarge it. Btw what glue do I need to glue pvc/rubber to metal?

    I imported a linear floordrain from the US and I'm wondering how I should make the connection to the drain pipe. Both are the same size. I also bought a "rubber drain base flange"(see link), because I thought I might need it for install.


    However, since I live in a condo and want to have the drain flush with the floor without making the floor much higher, I don't think I can use the "rubber drain base flange".

    The juristic and my neighbour downstairs probably won't be too happy if I make a hole too large to install that thing. Is there something like a simple connector to make it happen? 

     

    I think a rubber sleeve that wraps around the drain and the pipe will work with some glue or maybe clamps, but I'm not a plumbing expert so curious what you all think!

    I would suggest your guess is spot on ????

     

    My inner destroyer just couldn't help but confirm it. seems like solder to the pins. I already bought 1 sqmm solid core, not stranded. The connectors in the previous post requires the wire to be unstripped, Stripped wire might make the connection less stable? What shall I do?
    a. Learn to solder
    b. Just Wago it with a 2x wago 3 conductor
    c. I am stupid, and I shoulda just walk around the house to see if there were enough first connectors and connect it.
    d. Replace led strip with a 2 conductor and its almost plug and play.
    e. just do whatever, as long as it gets the job done, dont spend too much time on this as no one will see it.

    Make sure you get the correct type of 5050, they should look like this.

    Thanks, I just hooked up my meter on them and 2 of them are used as + and 2 of them are used as -. I understand how to make connections now between strips, but how do I do that with the first connection?

     

    I don't know how to open the original connector to take a peek without completely destroying it, but I guess they just split the 2 stranded wire and insert it to 4 pins?

    Looks like a standard "5050" LED connector which has 4 pins (for RGB strips), for your single colour strip just use two pins. I'm sure it's not beyond you to sort which two pins ???? 

     

    You can get the connectors from Lazada.

    Does this mean that the two pins on the sides does not carry any current at all?

    Thanks for all the replies, does anyone know why my philips 6w single color led strip has 4 conductors at the cutting point? I thought that was only for RGB, so how do I connect 2 wires from my dim transformer to the ledstrip? ofcourse I can connect using the original connector and just connect the existing wires, but I wonder how I can do this using my own connector.

    All conventional (incandescent) lamps are dimmable.

    A simple 40W tungsten lamp from your local hardware store would do the trick, 30 Baht or so (I've not bought one for ages).

    Thanks, I will keep it in mind. However, my dimmer is homekit compatible and the most expensive of the circuit, so i prefer a solution where I keep the dimmer in the setup

    Is there are led triac dim driver that can let me drive all 6 7W downlights? And in another room, there are 4 of those, I can just use the TE-36A right? I can't seem to find the same drivers as you showed me that is capable of 6x 7W. What are your keywords?
