Tight cable lighting: what do you recommend?

[matthieulg]

Good evening everyone,

I strolled on your very nice site without finding all the answers to my questions, I allow myself to ask them.

I am renovating a house entirely and I have exposed beams.

I decided for a lighting by cables stretched between the beams at 4 places of the living room-living room-kitchen of 30m² (aesthetic choice)

2 things I have a problem with in this lighting:
- The size of the transformer
- The consumption of spots (generally halogen)

I am thinking of replacing the halogen spotlights with 12V LED spotlights (3W consumption) x4 by ramps

and replace the supplied transformer with a 15W compact transformer?

1 / Will this provide sufficient lighting?

2 / Is there a better solution?

Thank you in advance,
good continuation.

Well if we sell: https://www.econologie.com/shop/alimenta ... teurs-c-59

The transformer must be housed in a cupboard ... no choice
With 15W even in led you will never have enough to illuminate 30m² so no that will not be enough.

If you want to obtain a lighting equivalent to halogen, because of the directivity of the 3W leds, for the moment: I advise to double the number of bulbs (significant additional cost but not the choice). Otherwise the Luxeons are very good for non-living rooms or office, hallway or bed lighting ...

Otherwise if you wait a bit, soon we will offer a 4W (1 * 4W) led model with a large cone ... equivalent to 40-45 W halogens (but sold almost double the 3W ...)

it's not 15W, it's 4x 15W

each of the 4 ramps would have its transformer,
it gives 4 led 3w

- for the kitchen worktop,
- for the kitchen / fridge table,
- for the living room,
- for the PC / wood stove corner

however, yes for this kind of application broad spectrum should be important.

I can hardly hide my transformers, or so far away, which must create significant line losses (low voltage)

It's already better .... but 4 3W led bulbs for the living room I think that it will really not be enough ...

Frankly you would put 2 fluorescent bulbs of 30W you would be quiet and it will cost you much less ... and you can always put 1 or 2 led ramps "for the look" ...

I think I'll take the classic cable spots.

I would change my 12V halogen lamps supplied by powerful and broad spectrum GU5.3 LED lamps when the range has grown.

in the meantime, I wouldn't be very green

Thank you for these responses!

(I still have a lot to see here! direction of wood-burning stoves )

[Christophe]

Uh wide cone you mean? The spectrum in lighting is something else ...

Then while waiting for the LEDs nothing prevents you from putting a foot lamp with a high power fluorescent, that's what we have at home ...

Hello Matthieulg,

I would have liked to know what you installed finally.
I too would like to put spotlights on cables but I hesitate between 230V systems (more difficult to find and more expensive) or 12V with transformer.
Apparently, there are no compact fluorescent bulbs suitable for 12V systems (GU 5.3, GU4) ...

[Christophe]

No there is no compact fluorescent in GU5.3 but there is a lot of choice in led, for example: https://www.econologie.com/shop/ampoules-led-c-90

...including SMDs which are more efficient than fluorescent

Comparison here (GU10 model): https://www.econologie.com/forums/test-essai ... 10087.html

Normally you can power a suspended cable system directly at 230 if there is 30 mA before and there is no risk of contact ... and no children in the area.

When it is possible to stay in GU10 it is better because the choice of bulb is (much) larger than in GU5.3: https://www.econologie.com/shop/ampoules-led-c-90

Hello Christopher,

thank you very much for these answers. I can see it more clearly now.
I am therefore thinking of heading towards 12V systems, in which I will place LEDs the first time I change bulbs (unfortunately the kits are always sold with halogen bulbs).

I have noted that I prefer GU10s, but so far, I have not seen kits with this type of 12V bulb.
FYI, here is the type of kits I found: http://www.paulmann.de/?Land_ID=1&Sprache_ID=3&1Menu_ID=84&Anwendung_ID=22&EcatAction=Artikel&Katalog=2460&Kapitel=7789&Artikel=94001&Sprache=FR#gross

You're welcome,

So to see it even more clearly:

a) It's normal that you haven't found it; the GU10 is made for 230V AC bulbs and the GU5.3 / MR16 for 12V bulbs.

There is no such thing as 10V GU12 bulbs, but you can imagine transforming (at your own risk) a 12V system with suspended cables into a GU10 system by removing the transformer and replacing the MR16 sockets with GU10 sockets.

GU10 socket = 230V = https://www.econologie.com/shop/douille- ... p-194.html

b) Paulman offers 230V cable systems so that means that on the security side it's ok: http://www.paulmann.de/?Land_ID=1&Sprac ... =7784#7784
with sockets of different sizes.

Funny there is only one of the 2 cables which is electrically isolated (the one for the phase? How do those, like us, which are supplied in three-phase 230V so no neutral?)

So you might as well take a 12V system with the 2 insulated cables (like ours) ...

c) Be careful when you switch to led, you will have to check the compatibility of your transformer (if electronic must be changed) and if necessary take one of this kind: https://www.econologie.com/shop/alimenta ... p-363.html
