You certainly did not! You listed a few shops! A Google link is not a list. I asked you, specifically, for a PRODUCT. That you MAY have personal experience of. You can't provide that, because you know elstimpo and I are right, it doesn't exist.

As you seem to have a struggle with using Google and websites as I had posted both a price and a site in post #1 I'll give you a link. Interestingly the prices have risen since then but those prices given were what I paid at the time.

Since you've shown yours, I'll show mine too.

My Screwfix were slightly different as they were 8.7W but also 806lm. They have also gone up slightly to £9.99 for 5, though they regularly appear in the e-mail deals they send me at lower prices. Toolstation currently have 10W LED lamps on offer at £7.50 for 5.

The B&Q pack of 5 are also 806lm (starting to see a theme) but are 9W. they don't seem to have any decent deals on at the moment, so are around £2.50.

The HB 7W is 620lm.

So ..... I guess the challenge then is to show that 806lm is not any good, and to prove that Wifey and I sit in the dark, when in fact we have always chosen a light level we like.

The Living room was originally lit by a 20W Phillips CFL that was there when we bought the house, so it could be priced at zero, or alternatively at around £80k (with a free house attached). That CFL died about 6yrs ago at an undetermined age of 14+.

Then we installed a triple light fitting with 3x 8W CFL's. However, Wifey wanted softer lighting in the evening, and we got 2 uplighters with 12W CFL's each. Because they are in the corners, they give off less light. The one nearest me now has an 8.7W LED, as I wanted to test one, but Wifey says it's a little too bright, and is now deciding if she likes the 7W LED or prefers the slower warming 12W CFL.

So ....... boring waffle over, hopefully I've explained why we both found the comments on here funny about sitting in the dark, choosing darker room etc etc etc.

Awaiting 'better value for money' info and links.

But in the meantime my position remains the same. If you don't have any great concerns/appreciation of the light quality, then buy a cheap one, especially when deals are available, and try it out. If happy get more, if not, stick it in the shed, toilet, pantry, loft, worklight, emergency replacement stash etc.

These must be rubbish?

10 for £8.99

I'm afraid I have bad news for you, they are rubbish.

I haven't seen, bought, tried or even been aware of them previously, but I paid B&Q £7 for 5 4.7W GU10's with 340lm.

Since I paid more, for less, it's clear that mine are much better.

Edit - Mine are 15,000hrs, so after 14yrs (assuming 2hrs per day kitchen use (sounds a bit high!)) I'll start to make my money back too. M.

I do like this forum but sometimes :wall:

My not so cheap (£5 each still) blamps or lulbs or whatever I should call them are, for my eyes, almost identical in terms of colour temperature and light quality to the MR16 halogens they replaced. They are all glass like the halogens which is also good (for me) as the light fitting was designed to show off halogen spots in all their glory. Anyway, as others have said, you have shown me yours, so here are mine http://www.tp24.com/shop/all-products/lamps-bulbs/led-lamps/3-5w-mr16-gu5-3-led-spot.html

This was not true of the "first generation" LEDs I tried first and which cost about £12 each (ouch). They had a definite green tinge to the light and a flouriness or dustiness to it too. It was so "not good" that I decided to replace them once I found the above by accident as I wanted some long-body GU10s to replace some CFLs and this was the only supplier I could find on the Interweb.

Anyway, the above are 3.5W, 270 lumens and as a I say are almost identical to 30W halogen MR16s. So, is 270 lumens enough? Well, hell yes. We had 5 x 30W previously and have the same light now and the same quality with 5 x 3.5W. I would defy anyone to realise they are not halogen when they are on and you cannot see the actual lamp structure...

No idea what the CRI is or how long they will last but then I never worried about that sort of stuff when buying blamps in the pre-LED and oh, so simples, world:T

I did hear that with the weakness of Sterling against the Euro, the parent Aldi company in Germany are subsidising Aldi UK products.

I like a good subsidy;)

are mine (and others) lamps giving off too little light,

I can see adequately with my 3 watt LED light sources and I haven't a clue how many bloomings they've got. I had my eyes tested three months ago and I have not had to have new spectacles for three years, so I don't think my lights are having a detrimental effect on my vision.

I am sure that "light quailty" or intensity matters to some people, but the majority of us?

Mr.Generous

Reading this thread has just given me a light bulb moment .... sorry.

I'm not being rude nor aggressive (just a little impatient) but you've been very quick to demand information from myself, so I think it's only fair for you to post the info now.

So, given the prices, wattage and lumens given, are mine (and others) lamps giving off too little light, as you have been repeatedly claiming, and could you please supply some links/references to what we are supposed to be buying.

I've tried briefly, but seem to be getting similar wattage and lumen figures (around 800lm) only for £6-£10 per lamp.

Thanks.

Do I assume from the silence that 806lm is ok from a 9W lamp?

I'm genuinely interested to know if this has all been a confusing misunderstanding, or if an expensive LED could deliver this for far less wattage.

BTW a CFL just died, no warning, just went off ..... speak of the devil and all that.

Don't shoot the messenger, but Screwfix have an end of catalogue sale on, which includes some reduced LED lamps. Ends 5th March, but is stock limited.

One of the offers is the GLS 9W lamps, 5 for £5.99.

Great, so we both agree that most people don't care, and I'm one of them.

So, in my personal opinion, of which I'm allowed to have too (yes?) then LED's are great, and are available really cheap now.

So folk can spend lots of money on them if they wish, and if they appreciate the difference, or they can spend very little money if they are happy to do that.

Are we cool? :cool2:

1) Most people don't care about CRI but an awful lot also do and the numbers of people who do are growing. They will grow further when more research about low CRI LED and health are published.

2) Cheap LEDs are available but the vast majoirty are not that great, will often fail well before the quoted lifespan figures due to poor components in power supplies and end up being a false economy?

3) You can spend your money on whatever you like. No one has ever said different. I've worked in this industry for a long time and state my opinions which you are freely available to ignore.

Are we cool?
