I may be wrong, but I thought the requirements for low energy only fittings was dropped when Part L(2010) superseded Part L (2006)
Part L 2006 here -

http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADL1A_2010.pdfLook at P20 Para 42 of 2006 - that seems to cover the mandatory use of special light fittings
I can't find a similar reg in the 2010 edition, the closest it gets is P14 Para 4.13, where it says to look at the "domestic building compliance guide"
that's here -
http://www.planningportal.gov.uk/uploads/br/domestic_building_compliance_guide_2010.pdfLook at P123, it clearly states that low energy lighting must make up 3 out of 4 light fittings but standard fittings equipped with low energy bulbs are considered low energy light fittings!
So no need to use funny fittings, just put low energy bulbs in normal fittings
