changing the light transformer?

sniggings

Got the philips bulbs, all seemed fine then after 5 mins 1 went off, when turning the switch on/off it would flick back on again for a second then off again, then a 2nd one went, turned the light off, then back on after 2 mins, all lights stayed on for 3minutes, when the 1st one when off again?

Anyone know the cause, does this sound like I have 2 dodgy LEDs or just not compatible with the transformer?

Are you running these Philips MR16 LEDs using the original transformers at 12V?

Have read of the following from a company who have some excellent knowledge of the LED market and may explain the problem you are having.....Why Well-Lit no longer sell MR16 LED’s....https://well-lit.co.uk/why-led/

If you are then best to remove transformer and convert to 240V GU10.

Cheaper LEDs may not be bright enough and may not last a reasonable time and may not have an extended warranty, which is what you need with LEDs.

Well-Lit have a 3 year warranty.

great, just read your link, seems I've just wasted £34!

LED technology is still relatively new and are not always a direct replacement. There is still much to learn and educate everybody about the issues.

Tell John Lewis as they are pretty reasonable with returns as this flashing MR16 problem is not new.

I'm sure you'll get ones that work, at least you know a little more now.

My best advice is remove transformers and go GU10.

Thanks, I'll ask JL for a refund, stating the problem.

I'll look into changing to GU10 myself, depending on cost tho, it may just be as cost effective staying with the MR16s, replacing the bulbs and fittings, will probably cost as much as running the MR16s for 3-4 years, as I've worked out using the MR16s for a max of 2 hours a day, would cost £21 a year...just pains me knowing each time I turn on the kitchen lights, I'm using 200watts :eek: which is more than the rest of the house lights combined.

The GU10 flying leads are about £1 each, so not expensive. The MR16s I had previously each had a transformer per light, which I could remove after pulling out the whole light fitting. Hopefully there is enough wire length to give you easy access.

Our kitchen lights seem to be on all the time this time of year.

it's an open plan kitchen (small) so the light is not needed most of the time.

They do give of some heat tho, so will at least look into the cost of swapping.

sniggings - you described very well, the kind of problem you'll have when the transformer doesn't like the LEDs - either not working at all, flickering, or only working for a while - so you know now that you need to buy a compatible transformer, or, preferably in my opinion, as in my original post, switch over to GU10. As I said there was no way of knowing really, without trying.
