Install cost lot higher for anything near as bright, depends how

For security you don't need bright, indeed it is counter productive as
anybody outside the pool of blinding light is effectively invisible in
the blackness and every bodies night vision is screwed up as well.

Security just needs to evenly illuminate the area so anybody in it can be
seen and that doesn't take a great deal of light.

I'm also looking at adding to the external lighting here and am tempted
by the IP65 10W LED things you can get for £20 ish but that price is
ringing the "to good to be true" alarm bell. Will investigate the Steinel
LED stuff from TLC.
