How to control outside lights with a brightness sensor

[Gast]

Iv been trying to work out how to turn on outside lights at a certain lux level. Ive got the lux sensor set up and at present displays the lux level but I can not work out how to turn the outside lights on and off using it..

I did have the lights setup using Dusk & Dawn pulses but need more control over them. I have had them working with a simple 'Less or equal' function block connected straight to the lights but that doesn't stop frequent on/off switching at the set lux threshold or other controlling mechanisms from a control point in the future like alarm flashing etc.

Thanks in anticipation.
