Rated 1 out of 5 by from Meh Worked for first few months, but as others have noted - leading edge not trailing so leds tend to flicker a bit. Once a few months in, started to need need a bit more force to switch on and as time has progressed, need to basically hammer it a few times with spindle cover off just to get it to switch on and off. Add to this now spins without stopping at either end of spindle travel. Order has disappeared from my history, so absolutely stuffed from taking back for exchange or refund. Not fit for purpose.

Rated 4 out of 5 by from Dimmer switch I bought this one to replace the exact same one I bought 5 years ago but had recently developed a minor fault where the push mechanism for turning the light on didn’t work every time.

12v led gu10 bulbs

Hello I am looking to use a 240v light fitting on a 12v circuit in my motorhome with no transformer and a 12v gu10 dimmable led bulb, will this dimmer work in this set up
Asked by: Hsdguuvbklfrf
Hi Hsdguuvbklfrf, No, the dimmer is specifically designed for 240V AC not 12V DC (or AC) so we could not guarantee it would function correctly (if at all).

There is no adjustable scew on the back of the dimmer I purchased. I'm looking to use this with 12v halogen spots (7)

Asked by: plugger24
Hi plugger24, This is supposed to be our NAB81P, which would definitely have an adjuster screw on the rear of the module (half way up on the left edge), but ScrewFix may have substituted in our newer model NAB81 (without the trailing P) which doesn't have an adjuster as it is `smart' so detects the load type and self-adjusts.

What lights can go specifically with this dimmer?

I have a chandelier fitting and there are two light switches in the room. One is wanted normal, the other I would like as a dimmer switch. Is this dimmer okay to have with another switch in the room? What bulbs from screfix can go into it?
Asked by: McTop
Hi McTop, Yes you can have a standard 2-way switch at the opposite end of the circuit to this 2-way dimmer, in fact that is exactly the setup it is designed for. As this dimmer is a Leading Edge type then any Leading Edge dimmable lamps should be suitable for use with it.

Why does the switch buzz when turned on? The light fitting has 5 x 28W G9 halogen bulbs

Asked by: Parvesh
Hi Parvesh, Firstly, the dimmer should be adjusted to non-LED mode (potentiometer on the rear fully clockwise). Next you will need to check for any transformer in the fitting, as this would need to be Leading Edge Dimmable in order to be compatible with being operated by our dimmers. If neither of these points improves matters then we will need more information about the fitting and lighting circuit, so please contact us directly at:-
