    Hi all,

    I’ve decided to take the plunge and LightwaveRF my home.

    I’m going to get a ‘leccy’ in to do all the wiring up, but I want to make sure I purchase the right products. I’m in a new build, and most of the light switches are fairly straight forward. However, my living room/kitchen light switch is a bit more complicated and I’m not sure if it can be replaced.

    It’s a ’4-gang’ socket (although one of the switches is ‘flat’ and unused). The first two switches control the GU10 halogen spot lights in the kitchen (4 bulbs on the first switch, 6 on the second switch), the next switch is the unused one, and the final switch is a dimmer for the 4 standard 60w bayonet bulbs in the living room.

    I’ve pulled the front off the light switch and this is what it looks like (click for full size):

    Will the standard 3-gang LightwaveRF switch be able to replace this?

    I think your problem here is going to be the 4x60W circuit, which exceeds the maximum load of 1 gang of a three gang dimmer (each gang is 210W I believe?)

    You don’t mention the load of your halogen circuits, but you can do the same calculation for those.

    As for your options…..can you put the incadescents on a separate dimmer? The single gang dimmer (again, from memory) is rated at 250W. Alternateively, can you replace those bulbs with LWRF compact flourescents? Or dimmable CFLs?

    Hi blowback,

    Yes, I could easily replace the bulbs with dimmable compact fluorescent lamps, if that’d make it work. So if I did that, do you think the 3-gang LightwaveRF switch would be suitable?

    BlowBack is correct, single dimmers are rated at 250W with triple and quads being rated at 210W.

    Be mindful of the GU10s also, if you have 6 of them and they are normally rated at 50W each, that totals 300W and is well in excess of your limit.

    Have a look at my entry here and that may be of some assistance in replacing your GU10s.

    You could certainly use a 3 gang switch to achieve what you are suggesting; however, as others have pointed out loading may be a problem where you have the 6 bulbs on one circuit. As a solution I would use dimmable leds (see the led bulb thread for bulb recommendations) as dimmable cfls are a bit temperamental and do not always work with the dimmers properly. The leds are also a direct replacement for your spots as they come in a gu10 fitting and you should then have no problem with the loading (and a considerable energy saving).
