LED fixtures have failed. What's the next step?

So here’s a thing. I replaced the 6 halogen spotlights in my kitchen with LED units. After two weeks, they suddenly all went out, and aren’t turning back on. What gets me is they all went out as one. It’s not the circuit breaker.

Full disclosure is that I removed MR16 sockets and transformers and replaced with GU10 holders, but that hasn’t changed any wiring topology (this is DIY non-notifiable stuff to my understanding). Snip; screw on chocolate box.

I can try some troubleshooting, but thought I’d ask here first as I’m a little wary of mains and spooked by how this could have happened.

Presumably you’ve tested with a 240V GU10 incandescent halogen and there is power to the lamp?

I don’t have a halogen, but yeah I can do some standard troubleshooting. Was just wondering if the all-out was a smoking gun of something.

The switch or switch drop seems a good place to start. Seems incredibly unlikely they’d all fail at once.

You sure you’re complying with Part P?

I’m with @Dermot, check the switch. Also it will be wired so the power comes to a junction box or the first fitting before going on the the others. Find this fitting and check the connections as it’s the one most lightly to fail.

Check continuity.

Be aware that if it is a nutral fault the nutral will be at 240v all the way up to the fault . So watch your fingers .

A quick check with a neon scrwdriver will tell you if nether side of the bulb is live (live fault ) or both sides live (nutral fault)

If you are worried about safety just put one hand in your back pocket and stand on a telephone directory . ( I am not talking the piss it’s a old electricians trick )

Thanks all. I’ll be looking at it in this afternoon’s light… standing on a telephone directory (well, figuratively).

With you left hand in your back pocket.

Yep. Nothing going through my heart.
