I'm trying to locate 3 tilt downlights with an overall width of 18cm preferably in chrome to match lights already fitted but it seems they are no longer available. Can anyone help ?

Hi
More and more customers are calling for help after downlights have been fitted by "Builder", "DIY" or "a relation".
First one fails then another, etc over time.
Low Voltage downlights with transformers are often fitted with too small cables, transformer too close to lamp (overheating), or no air-space around fitting.
Many fires are being recorded through bad installations like these.
I only fit or replace with Low Energy 240volt fittings/lamps
(low heat, no transformer and long life)

What if this is not what the customer wants?
They might want to be able to dim their lights for example.
Do you have a link to a document containing these statistics?
I've just been having a browse of your website malcg

What are these detrimental electromagnetic effects (c) you mention?

No problems - there are several dimmable Low Energy lamps on the market - try Megaman or Varilight
Customers usually don't mind saving £8 per fitting per year on their energy costs. This is quite apart from Building Rgulations L2.
There are switch dimmable lamps, which are still a new technology, and have not yet been proven. For examle, I can't (and wouldn't want to) use them with my touch / remote dimmer switches.
Yes there are advantages to fitting CFLs in some circumstances, but there are other circumstances where CFLs simply are not practical
Building regs have nothing to do with this. The regs on energy conservation does not apply when you install lights into an existing property.
The '£8' a year you save, how many hours a day does the lamp need to be on to make these savings?

I have had to visit two sites where fires had occured to carry out repairs. I have at least twenty instances in the last two years where circuits had failed or partially failed - on investigation I found signs of severe overheating at or near downlights, and if left fires would have resulted.
For links try http://www.electricalsafetycouncil.org.uk/stats.html for basics - unfortunately not broken down as much as we would all like
Your not up-to-date: try Megaman Dimmable Series - new forms being added weekly.
A 50Watt GU10 replaced with a 9watt GU10 Megaman on for 5 hours a day will save more than £9 per year in energy costs. A kitchen with eight lamps will save £82 per year.
See http://www.energysavingtrust.org.uk for confirmation
Tx for looking at my website (still needs some work!)
I quote the technical manual
Cables for a.c. circuits
Electromagnetic effects from incorrectly installed cables of alternating current (a.c.) circuits can cause heat to be generated in the metal of ferromagnetic enclosures, such as steel conduit or steel equipment housings. To prevent such heat, which may damage cables and other materials, Regulation 521-02-01 of BS 7671 calls for the following requirements to be met:
(i) Single-core cables armoured with steel wire or tape must not be used for a.c. circuits.
(ii) Conductors of a.c. circuits installed in ferromagnetic enclosures (such as steel conduit, trunking or ducting) must be arranged so that the conductors of all phases and the neutral conductor (if any) and the appropriate protective conductor of each circuit are contained in the same enclosure.
(iii) Where such conductors enter a ferromagnetic enclosure, they must be arranged so that they are not individually surrounded with ferromagnetic material, or other provision must be made to prevent eddy (induced) currents.
Also refer to BS 7671 Reg 521-02-01
Yeah I know about eddy currents, which will NOT be present in the arrangement in your picture.
