Emergency ( loadshedding ) lamps.

[Derlyn]

I know that these emergency lamps don't work when there are multiple lamps per lighting point ( ie. chandelier ) or multiple lighting points fed from a single switch.

Tried it many times .... it doesn't work ... period.

Now I see there are gu10 emergency down light lamps on the market.

I have yet, in all my years, never seen a down light circuit consisting of only one lamp.

Is there a difference between gu10 emergency lamps and ES or BC LED emergency lamps that allows multiple gu10 emergency lamps to be used successfully on a single circuit ?

If not, what's the point in selling them ?

Question - when you tested the multiple lamps on the chandelier, did you only use one emergency light, and the other were standard incandescent lamps or were they LED, or were all the lamps in the chandelier emergency lamps?

[Derlyn]

In a chandelier, even if you only use one emergency lamp it doesnt work. When the switch is in the off position then the emergency lamp either lights or flashes on and off. It actually sees the other lamps that are parrallelled with it as a closed switch.

[Justloadit]

From your statement you did test with all the emergency lamps in the chandelier and it did not work, is that correct?

[Derlyn]

Yes. As soon as there is more than 1 in parrallel, they don't work.

[Justloadit]

Mmmm interesting, they have made the detection circuit too sensitive.

I believe the light switch needs to be on for them to work. Bigclivedotcom did a video on how these lamps work.

[Derlyn]

You are correct. The light switch must be on. But if there's a power failure and you don't want the light to be on, then you switch the switch off. That's when there's a problem. They either flicker or stay on.

Interessting mabe they changed the circuit in the gu10 lamps. Have you tried it with only emergency lamps in parallel? Also not sure if i like the idea of lithium ion batterys charging all the time on some dodgy circuit.

[Derlyn]

These lamps are fine if there's a single lamp per switch. As soon as there are any lamps in parrallel with it on the same circuit, that's when they are problematic.

Mmmm interesting, they have made the detection circuit too sensitive.

Towards the end of this short video, the presenter talks exactly what I'm referring to.

Ok but what if both lamps are emergency lamps?

[Derlyn]

Same story. Try it, you will see it doesn't work. Haven't yet tried it with gu10 lamps, hence my original question.

[Derlyn]

Gonna do some experimenting soon and will give feedback when done.
