LED bulbs, or light-emitting diodes are today considered the lighting system that will replace all others. Many questions arise concerning them: what are the equivalences of power with ordinary incandescent bulbs, are they compatible with the variators? Do not they disturb other devices, etc.? What is certain is that they are very energy efficient, they do not heat, and they last a very long time.

Can LED bulbs be ordered back and forth by a dimmer?

Can we install a dimmer (Legrand's Celiane all-tube dimmer, for example) to replace a back-and-forth that controls "dimmable" LED spotlights. Should the other switch be replaced by a simple push-button? In this case, is the existing wiring (the two shuttle wires between the two existing switches) reusable? If yes, how? Can the drive be installed indifferently in place of one of the switches or is it necessary to find the one that receives the phase from the electrical panel?

It is possible to order a goes-and-comes by a dimmer. The sheet "Variator to replace a back and forth" answers this question. Be careful, however, that not all LED bulbs are compatible with a dimmer system! The "dimmable" bulbs, that you quote, are, but in the absence of this information, it is necessary to be vigilant on this point or to replace the bulbs by models compatible with this control system.

Fix incompatibility between LED lighting and TV on PLC power

I have a LED lighting installation in our kitchen. The LED brand is "PRO LED Lamps". This installation was done by a professional. When I turn on the LED light, the video signal from my TV stops (use CPL). What to do?

It seems that some LED parasitic indeed the signal of TNT. The cheapest brands seem the first concerned. A test must be done with other brands of LEDs. Consult your installer who will replace them at his expense if this assumption is confirmed.

Why an LED bulb stays in standby switch off?

Why LED bulbs manufactured in France remain in standby the switch "off"?

An LED bulb can operate with a very low voltage. A residual return on the neutral can explain this phenomenon, which does not appear with a conventional light bulb. Some bulbs have this specificity, others not, probably related to the characteristics of the capacitor built into the bulb. I do not think it's a peculiarity... French.

Can we install multiple LED spots on a single spot of light?

I build and I will receive my electric kit (octopus). I would like to know, if on a bright spot, I can put several LED spots? If so, should my central point coming from my octopus be apparent? Can we leave it in my false ceiling?

An electric octopus is a ready-to-connect wiring system, usually tailored to your home's plans. Electricity is an area subject to strict standards (NF C 15-100). If you have doubts about your abilities, use a professional to make these connections in compliance with the Standard.
Several bulbs can obviously be connected to a single light point. This is the case of a multi-lamp chandelier, for example. You can use it to power several LED spots, as long as their total power does not exceed the capacity of the circuit concerned. Add the power of the different bulbs. Divide the sum obtained by 220. You will get the total amperage of the luminaires. The figure obtained must not exceed the capacity of the circuit breaker protecting the circuit supplying the light point.

Lighting match between LED bulbs and conventional incandescent bulbs

I plan to replace all my incandescent bulbs with LED bulbs, but I would not like to lose anything in quality and especially in lighting power. How to make a lighting match for these bulbs?

It is very difficult to match these two types of lighting. The type of very punctual LED light (light emitting diodes) requires to multiply the number and combine them in a single bulb (spot type initially, but now also in bulbs type "bulb") to get a lighting significant, LEDs originally intended to mark rather than illuminate. Currently there are "bulbs" with several tens of LEDs. The lighting power now rivals that of an incandescent or fluorescent bulb.
Manufacturers suggest the following equivalences:

  • 1.5W LED = 25W incandescent
  • 5W LED = 65W incandescent
  • 9W LED = 100W incandescent
But today it is rather the notion of lumen that is taken into account to appreciate the equivalence of lighting power:
  • 15 W incandescent = 220/230 lumens
  • 40 W incandescent = 410/430 lumens
  • 60W incandescent = 700/750 lumens
  • 75 W incandescent = 930/970 lumens
  • 100 W incandescent = 1300/1400 lumens
