Yep, sorry 6ft x 3ft, I'm a Brit and we use those foreign metres and stuff here!
Anyway thanks for your help.
I can use 2 windows next to each other in one blacked out room. Room is 20ft x 20ft.
Can anyone recommend a simple control device.
Very new to all this so all and any advice welcome.
Oh and in the UK so excuse the time delay.
