now not cheap at £10 for 2 ordered on the first for delivery 16th or later arrived today :huray: :huray:
any way well impressed 0.4w standby 9.2w in use nice and bright for a 9w bulb probably around 60-70w equivalent
operates as it get dim to dark in the room have fitted one at the top off the stairs and it works brilliantly split second on around 30-60 seconds off :huray:

its not actually to save money its to do with annoyance lol
in my terraced house i have the top hall light on most off the time as the only light is borrowed light [illuminated via above doors from the bedrooms ]
so the light annoys people in there sleep but no light on makes the dark stairs a danger to visitors in the middle off the night
this solves the problem
it will never pay for its self at £5 a pop as the 9w saved for say 8hrs a night will save 72w a day 500w a week so at 12p a kw/unit/1000w thats 6 pence a week or around £3.00 a year by which time the bulb has blown -----------------




-------------possibly 2 or 3 times :huray:

I'll organise a whip round to pay for a taxi to the local bingo hall for you b-a.

Then we'll get the 'social' in to further organise your entertainment.

We have to look after our ageing population :lol:

But back on topic (sorry) - have you got to the point in your upgrades where you can 'stop' or is there still some way to go? And, given the cost issue (and this particular fitting is a point in fact) do the upgrades all add up to actual savings or, considering replacement costs etc, do you LOSE money overall?

ive been all led for years perhaps 4-5 now
initially bulbs tended to be corn type about 4w £20 a pop from china and not very efficient as leds go lol
to be honest i experiment knowing they will double in efficiency every 5 years or so whilst halfing in price i start with the most used then after a few months i look whats there buy another one or 2 ongoing
i have probably spent £200 over the years and saved perhaps a quarter off that as all my bulbs where low energy replacing "normal bulbs" by the late 80s in a similar one or two a month fashion as they then cost £25 [half a days wages]when first introduced early 80s

low energy bulbs to led give very small returns as a 50-65% reduction sounds a lot but replacing a22w fluro with a 10w led will save perhaps 120w a day 850w a week or around 10p over 70p replacing a 100w normal bulb

i love them i absolutely love them :huray: :huray:
the two i have are one at the top off the stairs and one in the kitchen
both are in areas where passing or occasional use is normal
top off the stairs perhaps 2-5% off the "on" time being used
with the kitchen having 2 bulbs i have replaced the larger bulb with the new bulbs being perhaps 5-7% as on on time as a through route to the bathroom but including kitchen use now they react very fast so no feeling off delay or discomfort through through darkness
i could off course save more by having both kitchen bulbs as pir but that would take it from a welcoming area illuminated close to where you step in to a dark area that become functional very quickly
but prefer the compromise off "basic" [5w light] with 9w pir to give fantastic illumination levels

I have some LED strip lighting fitted in the hall, the kitchen and the bathroom.

They run 24/7 and consume a total of 5W so it's pretty much negligible as far as running costs are concerned but they provide just the right amount of light to find your way around at night without having to put the main lights on.

I'm considering doing the same for the living room too - currently we have a candle in the (cleaned out) woodstove which does good duty but despite the missus loving that kind of thing it's a faff as they only run fro 4 days (cost is irrelevant as we sell these things and have 'billions' of them!).

Naw... total wattage is about 5W for the LOT (1 watt/metre ??)

Can't honestly recall the model, they were put in a good few years ago - basic self adhesive strips stuff, actually starting to fail in lots of places now so could do with a full change. They give out more than enough light to go to the loo by or even make a coffee late at night. I've got them at ceiling height behind a bit of coving and they reflect off the white ceiling.

If I wasn't such a lazy so and so I'd fit a battery backup supply and have all the 'safety' we need.
