Just had ceiling downlighters fitted and 2 of the 15 have blown within about
3 weeks of use (in different rooms).
What sort of life should I expect from them? Does anyone know of a cheap
supply (which I'll need if they continue at this rate)? Thanks
Most of the ones I fitted blew very quickly so I got a job lot of
Screwfix's cheapest ones which have lasted well (over a year now). I
reckoned the ones that came with the fittings were crud,
Screwfix do a 35W Osram or a 50W generic, both guaranteed for 2000hrs (about
2 yrs at 3 hrs per day)
See http://www.screwfix.com/app/sfd/cat/pro.jsp?id 614&ts 872 for the
NB ISTR that if the bulb is enclosed and overheats this shortens the life
Yup - I would second that - I fitted a 4 way unit and one of the
supplied bulbs went inside a couple of weeks, although to be fair all
the others are still going strong as is the screefix replacement.
Also make sure you get the right type of bulf for the fitting - don't
try and use a dichroic bulbs if the fitting is not designed for them
since they allow more heat to escape through the rear of the bulb.
I posted a similar Q recently regarding the 12 or so of these bulbs fitted in
our new kitchen, which were initially blowing at a rate of about 1 a week.
Seems to have settled down now, so I guess the originals were either crap or
maybe mishandled by being allowed to bounce around in the back of the pikey old
van the kitchen fitter used. Prices for these things vary enormously, but the
cheapest place for small quantities seems to be Lavers at about £3.50 each.
None of the Lavers replacements that I have fitted have blown yet.
I have had the same bad experience with original g50 bulbs supplied with
fittings and some replacements
My local "pound shop" is currently g50 of various wattages --- yes they
are a 1.00 each the same price as G10 and g20 bulbs and they seem to
work just fine I fitted one 4 weeks back -- needless to say I now have
several years supply .
Regarding bulb quality I had to stop buying car bulbs from my local auto
shop because of poor quality (before anybody jumps in yes the charging
voltage and earthing was checked and was OK), actually had to buy Bosch
380 stop/tail bulbs from Halfrauds to get them to last more than 3 months.
