Lighting is a PITA, as the councils don't like upsetting the bat's, even though modern lighting is far better...Definitely needs planning, I've done several applications in the past few years for them. If you need advice give me a shout.
Bloody Jobsworths, as I could put massive floodlights on my house for security, but no you can't possibly have 4 or 6 down lights on a manege for dark winter evenings....
