Steinel Twilight Switch NightMatic 2000 Black, Photoelectric Lighting Controller, Automatic Night-Time Lighting

I've bought a few of these over the years for various outdoor lights around our house. They are really easy to install and adjust, and work exactly as intended. Our original sensor from two years ago is still going strong.I did try the upgraded 3000 model, but I found the 2000 model much more simple to use as it allows you to override the lights and turn them off without it messing up any learning function (as the 3000 model has). It also means when you turn the lights back on, the sensor hasn't reset and just works. If you never need to overide the light you can just leave them switched on safe in the knowledge that they will come on at night and go off in the morning. Super useful.If you are using this to replace an existing dusk to dawn sensor, you will find this super easy to install. If you are installing the sensor to an existing light circuit, you will need to have some electrical knowledge or get a professional in.

Looks good and solid but this item is an automatic in-line switch from a power supply. Therefor because it will be powered from a supply It cannot be switched off by itself manually.It does not contain a switch other than the one automatically by using the sensor.I needed a single unit and found that a Timeguard switch for me is better which replaces the switch on the wall.

Good product, well made. Easy to set up and great performance (i.e. Sensitivity & coverage). Rather more expensive, compared to other products available - hence 4-star rating - but needed as replacement of near identical unit that developed a fault (albeit 10 years old) to ensure same fixings and wiring configuration.

Outside lights are all on a GJD multizone controller and I was getting bored of having to re programme the zones set to come on at night with the ever changing dusk and dawn times. I decided to give this a whirl and put it on the feed to the up down lighters on the outside walls. I found a spot where the up/down lights and any of the floodlights wouldn't be affected by it. Problem solved, works perfectly. No more annoying weekly re-programming.

Easy to install

This is the right switch, even if artificial light shines on it, it will still turn on correctly and turn off correctly. Best dusk to dawn switch I've ever bought, worth the money, bought some cheaper ones, you know the ones, that come in a blue box or is blue or is black in an oval shape, each one of them failed miserably.

This device was simple to install and works a treat. It is very well made and worked beautifully straight out of the box. It can be adjusted internally to alter the level of dark/light at which it turns on or off but I found it quicker to use a coloured gel over the sensor.

Does what it is intended to do controlling my outdoor lights. Only marked down by the first one supplied not working at all. Speedy replacement by Amazon
