Trailing edge for led bulbs, leading edge for incandescent bulbs. Scrap the high load dimmer blocks in cupboard, which are only suitable for tungston or low voltage bulbs and not suitable for dimming LED bulbs but are capable for on off function.

Some LED bulbs are not dimmable so you have to get ones that say they're suitable for dimming.

Its great how you engage the customer and explain what you're doing, bet it really helps clarify thoughts and work things out by speaking aloud

Fucking incredible to see you Delroy. Excuse my language but for the past 3 months my Sundays weren't complete without your videos. In the words of Peter Crouch, let's hope you're back stronger

There is a big difference between leading and trailing edge dimmers. Most older dimmers are leading edge therefore if switching to LEDs these need to be replaced. Also, the quality of LEDs varies a lot - buy good quality ones from specialists, not the junk that most supermarkets and DIY stores stock (although what they stock has improved a lot in recent years) but also take note of the minimum load that the dimmer itself and this is easy to get caught out by as LEDs re typically low load. The LEDs must specifically state that they are dimmable too.

Hope all is well Delroy. Looking forward to seeing you back.

Hi Delroy glad to see you are back I have missed your videos, you always explain everything so well for the KZfaq audience and to the client as well. And the most important if you don’t know something you tell the client you don’t know and then if need be you do research and get back to them.

Hi Delroy ive come accross these impulse devices before, theres only two advantages to them 1) the switch line is low/12volts so usually they are useful for lighting/switching in a wet area like a swimming pool. 1) they can handle larger loads than a rotary dimm,er i.e. 1000watts which was useful with banks of halogen lighting. You did the right thing removing them and putting LED rotary dimmers in. Also, most dimmers even modern ones wont like a mix of LED and halogen bulbs on one gang, many wont even work well with a mixture of different brand of LEDs. Best to have all one brand of purely dimmable LEDs on any one gang dimmer Lastly i would have suggested a 'dummy' module for the undercabinet lights, it looks like a dimmer module and will fit on the plate just the same, but it doesnt rotate and is on/off only.

I used a ceramic (I think) resistor across the live/neutral connections on one of the five LEDs I installed to stop the flickering. Similarly, I installed another resistor at the switch end to stop the bedroom LED flickering.

Looks like the last spark ran - nice to stay and get sorted. Great to see you back making content 😄

Nice to see you back Delroy. you seem to have a very nice way of finding the issues and smiling about it all helping out the client. Your a gem...

Yeah Delroy back 👍

Hi Delroy, Firstly, I'd like to take this opportunity to say welcome back, I know I'm not an electrician, but every time I watched your channel, it's always interesting, all the best to you.

Glad you back , from a sparky in the USA. The 3 small black boxes we call balusters they work best with halogen and other lights not led lights . Since he updated part of his lights to LED the run on drivers which won’t work proper on a baluster . You eluded to that in the video when you were talking about LED drivers .

Great to see you back delroy missed your videos 😊

Hi Delroy it’s a good thing you engage and communicate with customers during the job which I cant😂😂wish you all the best mate

How cool to see you working again.

Hey Delroy, great to see you back!!

So glad to see you back 🎉

Another great video Delroy glad to see you back

Glad to see delroy back keep the good work up

Great vid, well done for sorting through all that!

Great to see you back Del!!

good to see you didn't chuck it in Delroy

He's back! I hope you were able to get some of your tools back! Any chance they caught those responsible?

Always enjoy the videos, thanks for sharing

So glad to see you back!

Good to see you back buddy 👊

Cracking video dude. Well done for keeping your cool there and slowing down to work out what is what.

Hello from Northern Ireland Delroy-good to see you up and running again

really good to see you back after the robbery, was worried you may never return. Great job on this one

Great work I hope you charge him for your time to figure all that out ? looking forward to your videos again 👍👍👍

Great to see you back Delroy!

Glad to see you back buddy! :)

Glad you are back😊

Nice to see you back Delroy

Nice to see you back!! Doing a great job as usual

Brilliant to see you back Delroy 👍

Great to see you back Delroy 😀. I can see the guy who originally did the wiring saying 'It seemed like a good idea at the time' 😆.

Phew... Good to see you back delroy .was getting worried u were gonna pack up after the van robbery

Glad you’re back! Hope there’s more videos to come now? 🎉

Good to see you back

Good to see you back and hope you have put the theft behind you and were at least covered by insurance.

Well done Del another exciting video. from one brother electrician to another. Keep it up.

Yes It can be a complete nightmare sometimes you need the correct drivers and when you throw dimmable switching into the mix makes your day a lot more interesting 👍

Nice one Delroy was waitin for your new stuff.Grettings from Germany 😊

Nice to see you back. All the best from granpa elvis

The Goat is back👍👍👍👍👍

There is nothing wrong with that layout, Delroy perfectly fine.

Well done. ❤

Welcome back Delroy, I've dealt with those Impulse Xfrms before in a holiday home, they don't support LEDS I think - also they need a good earth, or you may get dim lights. I believe if you pressed and held the light switch button they dimmed. The ones I dealt with were all 12v Halogen. I think units were £100 + each to replace, luckily the new owner of the home no longer needed my services, so I dodged a bullet there with that lighting.

Hi Del. How was the process with the insurance regarding the van theft? Did you get fully re-imbursed? Glad to see you back mate. Looking forward to some more “oh my days” jobs 😂

I had an issue like this on a first floor lighting circuit.. after IR testing and checking all the connections at each point a C curve b6 solved the issue !

Great to see you again mate long time no see 😅

Good job

I wonder whether the client plans to have the electrical installation fundamentally and properly renovated in the “longer term”.

LED dimmers sometimes have adjustment to set the minimum dim level to stop the LED flicker.

I’m pausing the video 5 minutes in… The old electrician this, the old electrician that … Get him back then 😂😂😂😂

delroy uploading again

As regards to the lights under the wall units in the kitchen, it's possible that the driver wasn't suitable for dimming either.

Leading edge and trailing edge!

I wasn't able to watch the entire video a I'm heading into a meeting, but my initial thoughts are that the home owners have had a hand in fitting the lighting circuit themselves and the other electricians he's called out have clocked on and refused to sort out his mess... Yes, I could be way off mark in this instance, but I've seen it happen more than once...

Those drivers need to be swapped out for a LED driver to prevent the flicker. So there needs to be a Part 2 to this video.

Drivers most likely aren't compatible. From a quick glance, they look pretty old. A change of the driver would most likely fix the issue if it's suitably sourced

I suspect that you are looking at 12 or 24V drivers used for LED’s alternatively you may also have some 12 or 24V used for IQ bulbs. Be careful as they are different. Likewise dimmers used an 240V circuits are different to those used for LED’s. Other factors to consider are are they constant current circuits or constant voltage. Get it wrong and you will get a hell of a bang! Start from the bulbs to learn of their voltages and types. Also remember that not all LED bulbs are dimmable which might explain the flicker.

Where u been mate ? Missed ur vids ⚡️⚡️⚡️

Once you have the permanent live , touch each other line sw cable to live to see which lights turn on

Does anyone provide any software to document the circuit diagrams of houses?

You cant have 2 dimmer swiches on the same light Delroy

I get having dimmers in a front room or bedroom because it creates a nice chill atmosphere but why the hell does anyone need dimmers around the sink or cooker? That being said awesome work

Missed the funky music on the video delroy

Dimmers on undimmable LEDs will kill the dimmers AND the LEDs. The huge inrush charging the LED capacitors on each cycle is not good and the power factor will be in single figures!

Looks like some switch lines or feeds are crossed or mixed up. Needs all to be traced properly. Had a lot of this over the years. Where a DIY job was done and usually feeds get crossed or muddled up.

What is over most peoples head is a good dimmable led bulb essentially has a little computer in it (microchip) and thus needs another computer in the dimmer to 'talk' to it to work correctly otherwise one of them is doing all the heavy lifting Why do some dim and others not then? Answer: dimmable ones need a better computer because of how the lights work and unfortunately that makes them a bit more expensive - but if you dont, they will flicker and rhat will be annoying, i can tell you. Any questions from there are personal opinion/ on economics generally.. I think diy stores and supermarkets should display some dummys split apart to show how an led bulb is constructed because its more of a circuit board than anything else and i dont think people realise because of how said bulbs are pacakged and sold. They see the exposed filiment types but i do wonder if that is what most peoplw think is going on in a normal bulb as thays what they always were, visually anyway. Thats the anology i end up using with most older people when explaining about anything with a microchip in it that is controlling the item to any degree. Microchips are everywhere... Its literally insane. Even usb cables... Rambles

Those type of LEDs may not be designed to dim and flicker when the voltage gets lower.

Can someone help me please. Can a 63 amp 3phase breaker feed a 125amp 3 phase main switch for a 3 phase board.

Bet the upstairs lamps are non dimmable, change them for dimmable ones.

That laugh 😂

Been a qualified electrician since 2002 and never come across a load of what looks like transformers immediately after the fusebox 🤔 looks a very odd system ,

The customer made 2 mistakes…..1, hiring the original electrician and 2, hiring you 😂

Delroy the minute i dropped that switch front off and seen that hash up i would have said this ones not for me and walked.

We don't specify 12v anywhere now. As far as I'm concerned, it's redundant technology.

My 1st question would be , was the last electrician qualified???

Bulbs are the problem switch them all to halogen and it would be great you can tell that's been done by some expensive interior desinginer

😮 the whole house needs rewiring.lol😊

I hate dimmers 😡 most are never used.

Welcome back! Missed your videos. Hope all is well. Cheers from Florida.

Tell them to get Philips Hue all round and leave ALL the old-fashioned switches on. They can use their iphones to do it all then!

The client could talk under water

Gee what a nightmare 😂

Premieres in 30 days?

Some LED's are not dimmable

That's switch design and made in China. 😊

driver problem

What an awfully bland house with an overly complicated light switch

Switchline and feed around the wrong way on the pen! Cut back the birdsnest and wago. Sorry fella but i think you made a meal of this for 26 min video. But good luck to you..

You see people like this in screwfix all the time they make 20:15 the excuse that there buying for the electrician and they always want to buy of eBay or Amazon and they buy rubbish and expect us to repair
