With all the old electrics taken out from my garage, I have to give the contractor my new requirements.

Previously I used a motley arrangement of 5’ double Tri phosphorus tubes.

The area to illuminate is approx 5m x 5.5m.

Anybody know the range of LED modular panels.
Should I stick to tubes or go for LED?

The issue of LED panels seems to be the reliability of the power supply module that has to be used to power each one. No one here has had them running long enough to get useful reliability of the panels themselves but I think there might have been the odd power supply failure experienced by Malc(?)
If you want led panels then I'd be suggesting a reputable electrical wholesaler such as TLC and the longest warranty you can find. Your sparky might have some experience here. Everything will almost certainly come from China and with no real grip on the quality hence falling back on warranty.
Alternatively refit your fluorescent hardware and put LED tubes in those. No power supply issues as all the LEDs are in series in the tube. and on a sample of one that I have in my kitchen I've had no problems over about 3 years since fitting it. If the tube fails it is simply a case of fitting a new one.

I've got one failing panel, and the replacement doesn't work at all.

I should have said useful statistical reliability. Is that a failed PSU or the panel itself Mike?

Led dice themselves should be be highly reliable but being low voltage devices (about 3v DC each) the problem usually centres around how they are powered from our 240v ac mains.
Either a converter down to 3v or a series string to get higher working voltage (but poorer reliability) or a combination of the two.
This applies to panels, tubes and bulbs.

Bang on the money. No prizes for getting the third !

I currently have three prime examples of it. Alleged solar panels for trickle charging a battery.

I generally buy my electrical stuff from TCL, they were very good exchanging some 5yr guaranteed LED down lights which failed after about 18 months.

I was in hospital when they ripped out the old garage roof and lighting, so all of it got chucked in the skip.

The sparky will be on site on Monday so will sound him out.

I was going to put 600mm x 600mm square LED panels in my garage but eventually decided against it due to one reason or another, instead I started looking around at LED replacement tubes. We have a CEF locally so I bought 5 LED tubes from them of varying lengths and it's like an operating theatre in there now :mrgreen:
Highly recommended by me. :eusa-dance:

Depends on the fitting Mike. If you have an old 50Hz ballast (heavy iron cored choke, capacitor and glow starter, then fit the "modified starter" that comes with the tube and then fit the tube. If you have modern high frequency ballasts with no starter then just fit the tube.
The tubes tend to come with instructions.

Thanks Bob. I have an area of the workshop that has a couple of neons but needs a little extra light, so I might swap to LEDs and see if that helps.

The LEDs will have better low temperature performance too which could well help in a workshop environment.

FWIW last year I fitted an electronic ballast to our double flouro tube kitchen fitment. It needed rewiring but that was not too complicated. The result is flicker free lights that come on instantly and no humming.
I do not think therefore I do not am.

Bob's got it covered, in my case it was just swap the tubes and put in the supplied ballast and like Andy says they're instant and no flicker at all.

“ Even though you don’t always see it, all mains-powered light sources flicker – whether incandescent, halogen, fluorescent or LED.”

I didn’t know that.

Mike,

I have replaced all of the florescent tubes in my Workshop with LED ones. Some I had to modify the wiring but others just fit the supplied starter.
They came from a number of different suppliers mostly on eBay, and have been in use for the last 5 years or so. The instant on in very cold weather is very good, some of the old tubes would take 10 minutes to get to full brightness.

If you want a hand installing some in your Workshop, just shout.
Regards,
Dave

Kind of you Dave. Much appreciated. I'm in the position of owing you rather a lot of favours at the moment. I'll give it a go and if I run into trouble I'll be in touch.

My Florescent lights have been replaced by these LEDs and I’ve now got a proper electrical set up.
Had to clear most of my stuff out and remove all the shelves
Now to put things back!

You have got electricity? :o :o :o :o

We were down from 5am to 7am then 13:00 to 15:00 and tonight from 21:00 to 23:00

I have still not been able to test my my new sleeping machine.

During the day I run the genny. The LED lights flicker. Apparently it has something to do with the power frequency?
