    I'm getting all confused and don't have the right vocalbulary for the new dedicated low-energy fittings that ONLY take low energy lamps.

    I think I've seen at least 3 types. 3 pin, 4 pin, funny pin. What suffix/affix am I looking for? Does "PL" mean anything? Has anyone seen a website that explains the options perhaps? Are they like BeatMax and VHS and one type will become the norm?

    With the phasing out of incandescents is it still necessary to put these new fittings in a new build house?

    If anyone can shed some light on this I'll be grateful.

    From October building regs no longer require a certain proportion of dedicated fittings, just low energy bulbs to be fitted in any fitting. If your BCO is reasonable you might be better off negotiating to do this.

    I fear that the replacement bulb market will be larger than the new build market, and that the dedicated low energy fittings will not catch on in volume. If so, then the new developments in bulb technology will be focused on fittings for replacement with low energy fitting versions being slow to catch up.

    I think this is why the regs were changed.

    Not quite sure on the CSH situation, if you are aiming for CSH. I think you still get points for low-energy fittings so it might be worth considering.

    Thanks Mark. Is that October coming or past? We really should be done before next October, I hope! I'm struggling to find really plain single spots that don't need transformers and can take some sort of CFL. I'm not sure there's an affordable LED to do the job yet.

    I'd have thought any good airtight/fire rated spot with a high power LED GU10 will keep BC happy , especially with the future change coming in.

    Used these on several jobs and customers happy , http://www.tlc-direct.co.uk/Products/GULED5WW.html
    Yes still a bit pricey , though you should be able to get LED bulb and DL fitting for £20-30 each

    Normally you have to (only have to) build to the regs that were in force when you make your BCA. Your BCO might allow you to use whatever new rules come in this October but he could insist you work to the current rules.

    There are a lot of different bulb bases around but most have existed for years in fittings for commercial application (shops, offices, hotels etc). They tend to be sold by electrical distributors to the trades rather than retail outlets. In short you don't need to look for any particular bulb or bulb base. Choose a fitting that you like the look of and check the maker states it complies with Part L. Try companies like TCL. They normally tell you if a fitting complies with Part L.

    Just for info -The LEDs James linked to (http://www.tlc-direct.co.uk/Products/GULED5WW.html) appear NOT to comply with part L because they aren't efficient enough. 150 Lumens of light for 5 Watt of electricity is an efficiency of only 30 Lumens per watt and Part L requires > 40 Lumens per watt (or it did last time I looked). 150L isn't very bright compared to a 35W halogen's 600L (but might be bright enough). Do buy one to try before buying a house full.

    If you buy a fitting and find the colour is horrible experiment with changing the colour temperature of the bulb before discarding the fitting. I usually go for "warm white" bulbs as they are less blue than "cool white" or standard.

    These worked for us but I've not checked if they comply (probably do).

    This place has some Part L compliant LED downlights. They are twice the price of those above but produce twice the light output (example 9W at 42L/W = 360L)..

    This place also worth a look. The majority of their fittings meet Part L...

    I've never known a BC talk lumens , but yes your right
    I just go on , does it give enough light for the situation ? Whilst looking for the lowest watt solution.
    As you say always try them out , lots of different quality LED s out there.
    Your wall light comply , used those ones several times for that purpose

    Me neither. Mine was halfway out the door when he said something like "Oh I forgot, do you have any low energy lights?". I said "yes there are four in the living room and..." but he interrupted and said "that's fine" and departed.

    They are generally pretty lax/flexible unless you upset them for some reason.
