Too many lights on a single circuit?

[Taylortwocities]

The requirement for luminaires that could only accept low-energy lamps was removed from Part L a couple of iterations ago.

Before then, you had to have a certain number of light fittings (25% IIRC) that were low-energy and could only accept low-energy lamps. Now the requirement is that 75% of lamps must meet the low-energy requirements.
Now you can install regular GU10 fittings and put in LED lamps just for the BCO inspection, and then swop them for 50W halogens once they have done the sign off!

EDIT: PArt L1 (domestic) basically says

• 75% of all the lights in a home or domestic building must be low energy.
  
• A low energy light is only classed as low energy if it produces over 400 lamp lumens and has an efficacy of over 45 lumens per watt.

Note: Some LED downlights only fully comply with Part L in cool white but not in warm white.

I think our BCO will consider installing 24W of lighting an energy efficient solution.

Thanks for the reply ericmark,

Yes, we have broken areas into separate lighting circuits too. So we don't have to fire up the whole 36W for no reason!

Hi TTC,

That's a curious one - so how is a single lamp of <400 lumens treated? Not low energy? Not applicable? Not a lamp?! The lamps we have in the office claim to be 280lm / 3W so doing well on the efficiency front, but <400lm...
