Hello everyone,
I’m new here.
The house construction will soon begin. I have a specific question regarding this.
In the upper floor, the ceiling will be covered with plasterboard panels (12.5mm) (0.5 inches). Below that, a counter batten (24x48mm) (1x2 inches) and the vapor barrier will be installed. The collar beams will be insulated between the rafters. This leaves a free space of about 36.5mm (1.4 inches), in which I would like to install LED downlights.
Now I have the following questions:
1. If I install 230V LED downlights with a recessed depth of 26mm (1 inch), is this feasible?
2. Or do I generally have too little space for LED downlights?
3. What alternatives are available?
Thanks in advance for your help.
Regards
Beans

Not really recommended... better consider installing proper LED lights. These usually deliver what is promised on the packaging and are generally much slimmer... even as spotlights...What is the downside of 230V LEDs?

There are also GX53 spotlights, which are extremely flat.

The 230V before that... LEDs are low-voltage light sources... so with 230V you have a driver in front, which must fit into the socket. It should be clear to everyone that proper heat dissipation is practically impossible here.
And that is probably why the installed LEDs might last the specified number of hours... but the driver will fail relatively early compared to that...
But then it’s no longer a 230V LED light source...

LEDs do not operate based on voltage (12V) but rather on the required current (mA), which is provided by the driver.
If the electronics are integrated into the light bulb, the likelihood that it will NOT reach the hours stated on the packaging is quite high.
No longer than typical energy-saving lamps, for example, since their construction is similar. This is not just my opinion but a fact. Electronics age, and when subjected to heat, this happens very quickly. For example, consider the wave of LCD TVs that failed over the last 5-10 years due to dried-out electrolytic capacitors...
And the drivers in the sockets of LED bulbs contain the same electrolytic capacitors...
However, if the driver is external and it is a "true" LED fixture rather than a retrofit, then it could achieve the thousands of hours of operating life. Eventually, the color may change, but this is also clearly indicated on the packaging.
