Noticeable delay between 2 lights on same switch coming on.

[chrispwoolley]

Hello again, it's been a while.
I just replaced two integrated LED downlighters for exactly the same models, and there is a noticeable delay between them both coming on.
1 comes on half a second after the other.
They are both wired into a small junction box (1 feed into 2) rather than than looped from one light to another.
The lights I replaced had no such issue.
The last time that happened (different lights) the driver of one eventually burnt out.
Can anyone give me any pointers as to what might be the issue?

Cheers

Probably, there is no issue at all - some LED's come on instantly, some take a second for the driver to respond, before they come on.

Yes. Swop the two LED lamps over and see if the delay stays with the LED.

Do you have separate drivers?

Yes, separate drivers, built in each lamp.
I have disconnected and remade the connection to the 'slow' lamp, and it seems better.
I felt like the live had gone too far into the push-fit terminal block. Maybe it was touching the insulation in part.
I'll see how it behaves.
