Problem with Dusk till Dawn Photocell

[DistortedVision]

I fitted new outdoor lights with these dusk till dawn photocells:

I fitted them according to the manufacturers instructions and they function perfectly until the switch they are on in the porch is switched off or the MCB on the consumer unit is tripped for example. Simply flicking the switches back on won't reset the photocells. Has anyone any idea why they are doing this?

I'd be grateful for any suggestions.

Many thanks!

Such devices won't reset instantly when the power is restored. They need a little time to settle down. Are you being patient enough - and do you have the original instruction leaflet for the settings?
