downlights and part L help needed

[Limara]

help needed please
I am planning to fit downlights to every room in an extension with the exception of one light fitting in the dining room which probably wont comply with anything.
I understand that I can now have regular gu10s fitted with led light it then gets a bit hazy
techicnally they will be classed as the not counted as they will be under 5 watt, but surely we cant just have them all " not counted"
The way I understand it is 3 out of every 4 must have a min of 400 Lumen output I take it thats for each bulb and not a overall calculation this work is all under bc and could be very costly to get it wrong
at the cost these bulbs are.
and is this overall 3 out of 4 in the property or per room.
ie if I have my non comply in the dining room then " uncounted under 5 w in all the other fittings do I just have to have 3 x 400 = lumen output somewhere to comply to part L

With LED you are fitting low energy lighting, because they are not really bright enough to be counted consider the set of downlights in each room as one fitting. Then you have complied OK.

They were not considering that you could get >400 lm out of 5W when this was written. BC will not really be too interested anyway as everything is low energy.

To note the client can replace the led with diachroic 50w GU10's so these wont comply with part L so you cant class them as part of your energy efficient lighting ..... energy efficient lighting should not be inter-changeable with standard lamps so gu10's, bayonet cap etc wont comply.

Darkwood, I think you missed the changes 2 years ago or so.
It used to be the case that you had to fit low energy only fittings, which were expensive. Sense was seen, and now you can fit any type of fitting, so long as you use a 'low energy' lamp (for 75% of fittings). Yes, the customer can change them afterwards, but so long as you do your part, it will comply.
So, GU10 downlights with LED lamps are fine.

No I think he's right

 

[SPARTYKUS]

Who's right? I'm really confused now

 

[Darkwood]

MDJ who you referring to as thinking they are right? Im taking a back burner on this until I can look it up also to note 2013 amendments are coming into force throughout the year so I need to see what effect s these have too. Planning Portal - Approved Document L - Conservation of fuel and power Here's a good free download of Part L and new amendments I haven't time to browse myself yet.

afaik, the silly requirement to fit dedicated low energy lamp holders has been withdrawn due to the fact that it was stupid. as long as you fit the required proportion of low energy lamps, it no longer allows for dickeds.

Standard fittings with low energy lamps are ok

See page 123 of http://www.planningportal.gov.uk/uploads/br/domestic_building_compliance_guide_2010.pdf

It says light fittings may be standard fittings supplied with low energy lamps ... etc

It changed a couple of years ago

The rules changed regarding this not too long back at one time a low energy fitting was just that and they could not accept other lamps, now any old fitting can be used providing a percentage is low energy so I have heard, however As far as I'm concerned a low energy fitting should only take low energy lamps and I have heard nothing officially about this otherwise TBH Fella

October 2011 was the change.
We, as electricians should know these things, if not off by heart, then by easily getting a book out/reading a .pdf and then absorbing what has been written.
If anyone is doing any work in a domestic premises, they really should know these things, as you MUST comply to the various Building regs, not just Part P.
I'd recommed, as a first step, getting a copy of 'The electricians guide to the building regs', or better still, do the C&G Building Regs course.

I'd rather not, I will stick to commercial, I'd rather have my teeth pulled out than do domestic haha

As I said earlier its not my field of work ive enough trouble trying to keep up with the ever changing EU regs regarding machinery and control systems, the changes in part L are systematically been complied with by the very nature the way the lighting industry is turning ive been fitting LED gu10's for 3yrs now when I get the odd filler job when industrial is quiet ....its the case here that part L is changing in tandem with practices already on site and I don't see anything in the recent amendments and forthcoming amendments that would alter the way I do things so I not going to waste money on a course when I can download the free PDF of the government.
