Energy Efficent Lighting

[i=p/u]

well he said the fittings which allow gu10 led bulbs dont comply as you can replace them with i.e 50W halogens . but comply with another part as are energy efficent..


so my options are fire rated with an led bulb @ £14 a fitting but dont comply with building regs cause they an be changed

or £35 a fitting wich comply with both.. which i think is too exspensive for customer, well i think they wont buy it if nearly 60 fittings throughout

The earlier regulations stated that the fitting must only be able to take low energy lamps, however this is now no longer the case, even if you can change the lamp for a non energy efficient one this does not matter. See the attachment on my post no 3 and read the supplementary information in the blue column.
This describes the two options.
LED lamps can also be considered low energy with integrated control gear.

If price is an issue then you can use Gu10 CFL lamps as they meet the >45lm/W requirement.

i know you get ten years warranty and all with fittings but some amount for lighting.. but i dont even know if money is an issue, ive just got the drawings here and working out all my options to look and sound professional..

In accordance with The Building regualtions Part L1B and the Domestic Building Services Compliance Guide 2010

and how would you compare them to the normal halogen..


is 12v with transformer an option in energy terms

when i drive past a government/council office building at 2.00am and it is NOT burning megawatts of lighting in an empty building, then i'll consider fitting ugly energy saving lighting. until then .... practice what you preach.

That makes no difference to the energy consuption of the lamp at all.

Be careful with the building regs if your working in Northern Ireland, they aren't the same as in England and Wales. Part F is what you need to comply with (Part L in it is about Heating Appliances etc).

As far as I am aware we still need to have the dedicated low energy fittings for 1 in 4 lights - it certainly was the case end of November when I last had any dealings with Building Control.

Apology:

Sorry I=P/U I had forgotten you were in NI, different rules!! Also different rules apply in EWS for non dwelling locations where the average efficacy should be 55lm/W. but may be again different in NI.
Also I have just calculated the lm/W of the GU10 CFL and they are actually about 22lm/W.
Most fluorescent lamps are over 45lm/W and I had assumed these were the same, I do apologise for giving inaccurate information.

This extract from the TLC (horror) technical site and this extract from the illuma catalogue gives some useful rough lamp data:
