i believe there is a 150watt limit on flood lights?

is this domestic only or does it apply to commercial too. Only asking as i want to fit a couple of 200 watt ones in the back garden.

On all the time, lighting up the property or trees etc. Or for security? 

sensor activated with manual override so security and convenience.  

150 watt limit by who? What's the application?

 

I have a 200W LED low bay kicking around somewhere that is designed for commercial. All I need is a lens and a dead bat to summon Mr H...

You'd need the prat symbol, not the bat symbol...

there's some shite about the wattage of halogen tube

 

(it is /was harder to buy 500w?)

 

however light is measured in lumens,

I thought bat was your chosen weapon for printer slaying?

 

EU phase out of incandescent has now been followed by halogens, doesn't have anything to do with wattage AFAIK.

 

its something to do with Part L

http://www.lllwww.co.uk/building_reg.html

 

but this may only be new builds?

reading this I assume if the fitting exceeds 45 lumens per watt there is no limit? (table 42 page 81 of attachment)

 

my fitting is 17000 lumens at 150 watt on the front

That would only be for equipment fitted to pass building control, so new builds etc.

Your fitting would be 113 l/W anyway.

Who would care enough to be an issue?
