Am presently on a job where the customer has 7 x GU10 fittings with Kosnic 5W LED dimmable lamps.

These are presently controlled from a single conventional light switch.

Customer has had a new kitchen fitted and wiring is present for 4 undercupboard lights.

Having checked, the wiring for the undercupboard lights is off the same switch as that for the ceiling lights.

Customer wants to fit single LED light fittings under the cupboards and wants to be able to swap the conventional light switch for a dimmer switch to control the lot.

I has asked around a few wholesalers but no seems to be able to advise further in terms of what is compatible with what - i.e. certain types of 'all in one' (LED lamp forms an integral part of the fitting) fittings would live happily with both the proposed dimmer and the existing retrofit GU10 LEDs.

Another suggestion has been to fit conventional tungsten lamps under the cupboards and retain the existing ceiling LEDs, but again, would the combination of a dimmer switch, the LEDs and e.g tungsten lamps all coexist happily together? Or do potentially expensive failures lie this way?

The bottom skirt (or 'pelmet') which runs along the underside of the cupboards has a depth of 50mm, so any suggested fitting would have to be less than 50mm thick in order to conceal it.

Am open to any hints/tips for suitable products would be most appreciated.

As far as dimming GU10 LEDs go, I've had only good results from a Varilight IQ dimmer, and now use them wherever possible. They also work with the sealed LED units. Never tried them together on the same dimmer though, but I think if you're going to mix lights, this dimmer would be a good bet. Though I'd check to make sure any LED fitting is from a good manufacturer and is made to be dimmable
Good luck!

flexible led ribbon would be ideal for your pelmet lighting.
can be made to length and looks very classy.

I had some feedback from a manufacturer via a supplier a while back and they reccommended the Varilite trailing edge dimmers as well. Different ones are better depending on total load. mine varied from 12w to 30w from memory as i needed 3 different switches.
The one i was reccommended was the Varilight V-Pro.
part no. JQP401W.
COST £12.50 INCL VAT

Thanks guys,

This varilight dimmer sounds like a useful bit of kit.
The only problem is that it has to cosmetically match the rest of their new accessories which are Crabtree Platinum range items. Failing this, I suppose one solution might be to buy a Crabtree item and swap the varilight electronics bit over to a Crabtree front plate (screwless type).

In terms of LED strip, I've never fitted any. Does it come prewired with a mains lead? And can you get it with a 300k colur temp rating? Or is it all in that horrid cold blue light?

Varilight do a range of finishes :-) but yes, you can buy dimmer modules separately to save a few ££ and have a perfect match. I don't remember them being any bigger or smaller than normal modules, but it's worth checking
And strip LEDs will come in a range of colours too! Usually you'd get the driver and leads that will either clip into the driver or from strip to strip

// it is probably worth mentioning that I am not affiliated with varilight in any way!

LED strip is a good idea, though the stickiness of some of the stick on strips may need to be supplemented - read the buyers comments if you buy online.

I don't believe you can mix standard and LED lighting circuits from one dimmer switch. A standard dimmer needs about 20W to work properly so wouldn't like it if the normal lamp failed and only the LED were connected. Several of the websites selling LED lamps also give advice on which dimmers they recommend (and sell)

It would help if the interpretation from Indian to English was spell checked before being released on their website!
