Floodlights

Wha too you land to do with them? Rent out the pitch? Training? Matches?
Remember that installing lights on most pitches will wreck the pitch, even with limited usage. Clever clubs install lights on their 'second' pitch.
Cost benefit analysis says forget it!!
Have seen them vary from @65k (useless) to €150k (super). Get yourself an electrical engineer to draw a plan, having first decided the potential usage.

Possibly need a generator too as ESB may struggle if your not located well for them. Although the upside of a gen is you pay before you use it so no nasty bills landing in the club.
