makes me laugh when people comparing about cfl warm-up time, like you need optimal luminosity the second you enter a room.

This is what you call a light bulb.....................................................................

20,000 watt light bulb test

Now watch that and tell me you don't smile!

Popped back to this thread to say that these now say end of range and reduced to clear in my Tesco.

There's no 3 for 2 offer on the bulbs that cost 88p in the Bristol Eastgate store. Still, good deal.

Thanks for posting this. This will save a lot of money on energy. For bayonet type fittings, if you're trying to replace old style 100W or 70W bulbs, it's hard to get lumens per bulb at or above 1000, even with LEDs, and that's leaving aside the one off higher purchase costs. So some of these higher powered ones Tesco are selling are very good value.

Should be 19th to 29th

looks like it has expired :disappointed:

Great find op

Cool story bro'

When cfl bulbs were sold at 10p each in many shops i bought over 5000 edison screw and sold them in Spain at 3 euro each....everybody wins......the energy companies that subsided these bulbs got carbon credits.....Tesco's got 10 p each to "give" them away my spanish buyers got them for around half their shop price and i made a huge profit.............enough to pay my uk electric bills for at least 10 years,.

7watt cfl =40watt incandescent
11watt =60watt
15watt = 75watt
20watt = 100watt

£4 for Philips led in b and q that I got, far better

​Yet you got to wonder how they can still advertise them at this price (guessing that adds up a premium!?). Stock Clearance!?

​Yes, get two 800lumen bulbs or install a dedicated led fixture (such as a linear led tube or similar).

Old technology - LED lights are only a little more expensive, and better in a number of ways. Of course if you are still using incandescent lights, these are much more efficient.

The LED chatter.

Yes they may be more efficient, but how many years do you calculate it will take to recoup the additional cost?

These bulbs contain mercury and use way more energy than LED.

heat added this should b mega hot

Yeah mines in the hall and is only one every now and again, agree not good in a room to feel warm

Did you find the light a bit "harsh" on these though, I got some similar priced ones from Toolstation last year and though they are bright, skintones can look very grey under them. I tried one in my downstairs loo but it just made me look ill when I looked in the mirror! Got a warm filament one in now, much softer. CFLs do tend to be better for skintones, but they are annoying in places like toilets when you really want instant on lights.

what is the average lumins mean please

Good price, but agree LEDs are the way to go. The long warm up time is the handicap on CFLs. There's some good filament LED bulbs around these days from about £5 (Asda do some). Filament bulbs are also even more efficient for the lumen output than "normal" LED bulbs, and the light output is 360degrees (so you don't get a large shadow on the ceiling) The one I got in ASDA is a 7w one with 810 lumen output. You need about a 10w "normal" led bulb for that kind of output

Cheers OP.

They are good, particularly for the price though still only half the lumens asked for. These...

are 1521 lumens though nearly £19 each.
I've used these
http://cpc.farnell.com/pro-elec/hk-ld432a-bc/lamp-globe-led-12w-bc-dimmable/dp/LP07975
which are £6 and emit around 1200 lumens. Available slightly cheaper if dimming is not required, also available in horrible warm white. :wink:

I Got these and they are bright

Clicky

awww wish I'd seen this deal earlier as was in tesco before....

Great price op, tescos it is, heat

That's more like it pricewise.
