Rated 5 out of 5 by dimmer switch Replaced this dimmer with a older one that had started playing up (it was 10 years old and used everyday). loved the fact it only took one minute to replace (got to love the mk grid system). I would buy again even considering the cost. 17 Dec 2014
Rated 5 out of 5 by Brilliant dimmer Grid switches offer a great solution to mixed switch / dimmer requirements. Really nice dimmer - good solid terminals, nice soft start and no flicker. Worth paying that little bit extra for. 30 Oct 2014
Rated 3 out of 5 by Reliability Issues Have installed 4 of these on one job, so far 2 have failed. Customer not happy and i'm very disappointed with the reliability of these MK products! 12 Aug 2014
Rated 5 out of 5 by Perfect for the job! Needed this for a domestic installation in conjunction with 2 normal on/off switches. Gives a smooth control of the power to bring the light on gradually. No buzzing like some dimmer switches with energy saving lamps. Only one issue which was the push action of the on/off sticks a bit, but I'm sure that will ease with time (only reason I gave it 4 stars not 5). Little bit on the pricey side, but MK gives you quality which goes towards compensating that. 3 Jun 2014

LEDs

With the introduction of LED replacement lamps that are dimmable would this product be compatible ?

Answer: 
I've installed with LED GU10's fine. Will just have to ensure you have enough lamps to meet the minimum voltage, which I believe is 40w, however I'm running it with 8 X 5w dim able lamps and there is a slight hum

Load rating:
For single dimmer installations:
K4501 min. 40W/VA, max. 220W/180 VA

For multiple dimmer installation see Load
Adjustment table

Answer: 
I believe the minimum draw is 40w (found on another websites datasheet)
I've installed it with 8 X 5w LAP dimable led GU10s from screwfix and it works fine. There is a slight hum though.
The fit is snug in a standard depth back box with any amount of cabling so I would recommend going with a deeper box.
