Commercial lighting is a world apart from residential. Not necessarily incompatible (all has to get to the same 120V or 240V, except for some really big lights in stadiums, etc.) but not the kind of stuff you'll see in an ordinary retail store/web site. In the case of IKEA (similar for any large chain), it is quite possible that they used standard fixtures, ...

The old power supply outputs 12 volts AC intended for older 12V lighting designs (may work with LEDs but probably wouldn't dim). The new power supply outputs 12 volts DC. However I don't see any recognizable testing lab marks on it, which suggests to me it's cheap Chinesium that you got mail-order, which is probably not a safe device. Your idea of connecting ...

I doubt that the LED light is heavy. Most LED lights that size are very light in weight. I would use the screws that were in the rectangular wall box to secure the mounting bracket/cross bar to the box. The load on the screws will be perpendicular to the barrel of the screw and should be fine. If you don't have the original screws you can pick them up at any ...

That is not correct. You have the 11.8V AC (low voltage) output of the old power supply connected to the line-voltage input of the new power supply. That’s wrong and it won’t work. Disconnect the line wires from the input of the old power supply and connect them to the input of the new power supply. The two power supplies have different output specifications ...

First you need to verify the fixture is UL/CSA/ETL Listed for hanging on a wall, the installation instructions are part of the listing. (NEC 110.3) Then the NEC says: 314.27(A)(1) Vertical Surface Outlets. Boxes used at luminaire or lampholder outlets in or on a vertical surface shall be identified and marked on the interior of the box to indicate the ...

Usually too much heat over a long time. This is most likely to be caused by high wattage incandescent lamps (perhaps 100W), or enclosed light fittings with insufficient ventilation.

For an office, yellowish 2700K light is not ideal. I like 4000-5000K color temperature LEDs a lot better, especially with lots of lumens and high CRI. I used these LED strips in suitable aluminium profiles, along with a 24V Meanwell power supply, remote controlled dimmer and corresponding remote (the round one) because I didn't want to install extra wires. ...

You're going to need to connect the two blue wires together with an additional piece of blue wire, the two brown together with an additional piece of brown wire and the same for the yellow/green. Use approved connectors, I don't think wire nuts are allowed. Then connect the single wire pieces to the light fixture. You should install a junction box there and ...

Best option would have been to purchase a universal mounting bracket that would give you every possible combination of screw holes to make anything fit.
