In my current rented house, the mix of ES, BC and various shaped reflectors
(in ES base) is a right pain - always seem to run out of the lamp that just
blew.

Thats the problem with all mains voltage reflectors, lamp life in, er,
just hours.



Metal halide, high pressure sodium and high efficiency fluro are good
ways to go for general area lighting, if you`ve got the celing height
uplighters are available in all of these sources. Not reccomendation
just an idea of whats available outside of B&Q, John Lewis and BHS:

It is an idea. Certainly for outside illumination, some of those offerings
would be better than x-100W halogen tubes.

Main problem with MH in interiors is lack of dimmability , available
in colour temperatures other than blue artic white nowadays, CDM lamps
are particularly good.

Other problem both outdoors and in, is they wont hot restrike , need a
10 minute break to cool down before relighting, makes them a bit
useless on PIR triggers.

Commercial downlighters also make some sense in some domestic
applications:

Screwfix one is a high frequency ballast accounts for difference in
price

Interesting - thanks.

Mag ballast can have power factor of less than 0.5 on a commercial
meter in matters, if your trying to be green in matters, because the
fitiings actually using an extra 50% of labelled power heating up the
ceiling void.

2 sets (7 total) 12V G4 lamps: used where SELV is a good idea (TM)

Fluorescent striplights for under cabinet use.

Stick to T5 which is a standard rather than T4 which is anyones guess.

Thanks for reinforcing that - had heard other musings to that effect too.



Anything else: standard size BC base - lots of decent CFLs in this
format.

ES, E27 is a more common continental base , but B.C . implies hanging
pendants , probably only good for the airing cupboard nowadays and
even then theres a case for LED...

I'm going to have some hanging pendants - hallways probably.

Which is where the warm up time of CFL has never helped, its pitfalls
at every turn just trying to light your home ;-)
