Dimpull - Bathroom Pull Cord Dimmer

Hi, I se this says it is trailing edge but not suitable for LED. I have LED dimmable lamps with built in transformers that says they require a derailing edge dimmer, so I am confused. Can this product definitely not be used for them? I have https://www.screwfix.com/p/lap-fixed-led-downlight-contractor-pack-chrome-370lm-5w-220-240v-10-pack/868fj thank you
I don't see the question as having much relevance as we have not had stock or sold this product since May 2019. if you have one installed, or laying unused in a shed, will it work? We don't know. It will not break anything to try.

You say that the dim-pull wont work with LED lamps, is it the case that it won't dim but can still be used as an on off switch?
If you are not wanting to dim the fittings, we would recommend product ref: 4061. This will work with the LEDs low load.

Will this dimmable pull cord be compatible with 230V IP65 8W Fire-rated LED dimmable recessed Downlights?
Unfortunately the dim-pull is unable to work with LEDs

I want to replace my single pullcord switch with this new dimming version, however, with just one live, neutral and earth wire, do I wire into the ````load```` side of the unit or the ````in```` side instead. Cheers.
You will require a neutral and live supply to the dimmable pull switch so this can operate. The live load out to the lamp is switched/adjusted by the unit. The neutral supply can either come direct to the lamp or via the dimming unit. Your electrician should understand what is required.

Does this product have a limited life as normal tungsten filament bulbs are phased out?
Standard tungsten lamps will eventually be replaced with tungsten halogen lamps which are more efficient. These themselves will be replaced at some point with lamps that give more light and use less energy. The long term future is undecided as the technology behind LED lamps changes very rapidly. However lamp manufacturers are very keen to produce new technology lamps that will operate on pretty much all control gear (switch or dimmer unit) as this is where the rewards (high volume sales) are greater. So the future of this product can still be regarded as viable in the medium and long term.

If the switch is pulled & the lamps are at full power, then they are dimmed to, say, 50%. When turned off, I gather with just a quick pull, and then turned on again sometime later, will they initially light at 50%, or whatever they were set at when turned off, or will they light at 100%.
The output always starts at 100% and is dimmed by holding the cord. There is no memory. Full output is required to initiate an extractor fan which are linked on the same circuit.

Is it 2 way switching?
No this pull dimmer is only made for a 1 way lighting circuit as most bathrooms only have a single door and switch location.

You say that the Dimpull can be used with a fan. The people at TLC Direct say it can`t. Who should I believe?
We have had one report in six years of a fan not working with a Dimpull - the fan model was an Airflow QT100T. No other fans have been reported to have a problem.

I am confused as to how the Dimpull may or may not work alongside a fan. I am buying a new fan anyway, so it is as much to get the right type. Advice I have read on these says that the fan works because the power when first switched on is enough to start it (I am assuming this refers to a timed one). But surely if the lights are dimmed the fan power is reduced?! Am I better off with separate pullcords (or is this the only way anyway?)
All but the cheapest bathroom fan have a built in timer. Fans with a timer require two live feeds; one via the switched lighting circuit (pull cord in this case) and one unswitched live. When you use the pull cord a relay is energised in the fan. The fan then uses energy from the unswitched live to operate. When you switch off the lights the relay stays energised for a predetermined amount of time, then disengages and switches off the supply from the unswitched live. So by providing full current when the lights come on the fan will work. Dim the lights and the relay stays energised. Switch off the lights and the fan runs on it`s timer for a period and then shuts off. If the fan operated on the a single live feed the fan would slow down when you dimmed the lights!

Is this suitable where a bathroom fan is installed?
Yes it can be used in a bathroom where you have a bathroom fan installed. When first switched on the output is near full, triggering the fan.

I have just had one of these installed and although it dims the lights, they never come to full brightness, so the bathroom is constantly much more shadowy. Can you suggest why this is - I have 4x50w low voltage bathroom downlighters, and before the dimpull was installed it was very bright.
The maximum load on our unit for LV lights is 175 watts. You use the rating of the transformer when calculating the load i.e. 4 x 60va = 240watts. Your dimmer module is overloaded. You`d need to switch to a single 150va transformer and 4 x 35w lamps to operate in the range of the dimmer. Or remove the dimmer and go back to a standard on/off pullcord. Even when the pull dimmer`s load is within it`s range the lamps run at around 90% of their normal output.

Does this pull cord dimmer come with both the chrome and white plate or do you have to specify which you require?
The dimpull is supplied with both fascias

Can this be given a quick pull to switch on and off at the level last set, i.e. used as a normal switch by those not familiar with its operation, or does it have to cycle all the way?
Yes this Dimpull fitting can be used as a standard light pull - i.e. switch the lights on and off. If you wish to dim the lights you continue to hold the cord in the down position (as though you were going to turn it off but don`t let go) and the lights will dim, keep on holding and the lights will go up and become bright and so on until you let go at the desired level of light.
