LED Bulbs. Help!

patman99

I have had a SMD go bang before now and it wasn't one of the cheapo Chinese ones (which work perfectly well on the 230v UK power supply. It was an expensive unit from Philips.

The cheap and cheerful Chinese ones I have in my home are still going strong after 1 year.

You need to remeber that 90% of the SMD/LED buls made, come from China and if you go to the right supplier, will work across the power range from 110V to 240V (just like laptop PSUs).

The bulb that blew was examined by a retired electrical engineer I have known for years and the fault turned-out to be a dodgy PCB.

No, no they won't..... There's nothing even remotely like a switch mode power supply inside them.

Do you know that you can quote multiple messages in one post?



If they "seem" brighter, then they are brighter to me. That's what counts. And when you say halogen and LED are different, then it doesn't necessarily mean that halogen are better. It's very subjective. Most people say one is better than the other because they are just used to that kind of bulb/light.

If they 'seem' brighter that doesn't mean they 'are' brighter. If you take two lamps that are identical in all everything but one is 2700k and the other 3000k, then the 3000k will 'seem' brighter but it's factually incorrect to say it 'is' brighter because it's not.

I was merely pointing out that the vast majority of people are buying LED Lamps to replace and re-create the feel, colour and quality of light of halogens and incandescents and almost without exception LED's are not up to that job.

Oh and high CRI Lighting, be it halogen, incandescent or LED is far better than medium to low CRI lighting.

elstimpo - I know you are not overtly touting for business here and only trying to help others but I think you should mention that you run an online LED lamp store so that other posters know that a) you know what you are talking about and b) you have a vested interest in steering people towards a certain kind of bulb sold in your shop and not many others.

I hope you don't mind me saying that but I feel it is relevant to others.

I've stated that i own an LED store many times on here but i cannot state it every time i write something, surely?

What 'certain' kind of bulb am i steering people towards? I don't think i'm doing that at all. I'm just giving people the right information with which to make an informed buying decision.

I've never named my company or named a product i sell or linked to my own company and I have posted unbranded guides to LED to help as well has giving advice where i can and we make virtually nothing from my postings on here.

So i feel some of your comments are unfair. Happy not to contribute to any LED Lighting threads in the future if thats whats wanted.

Have just bought some LED spot light bulbs from Aldi of all places.

Used to be able to buy the standard R80 bulbs for next to nothing in a big multi-pack box of six, now you can only buy them in singles and they cost as much for one as they used to for six.......

I don't really like the light output of LED, the light bandwidth is extremely narrow, they give everything an odd hue, but at £4 each they were half the price of a single CFL.

Interesting, why?

Those with SMD seems to have wider beam angle.

These ones.... "If you are looking for LED's that produce the same colour, quality of light and brightness as halogen and incandescents, then only two companies in the world have products that can do it."

I don't think i'm doing that at all. I'm just giving people the right information with which to make an informed buying decision.

Sorry you feel that my comments were unfair. I don't think you should stop posting but I do think you should mention your personal interest - perhaps put it in your signature in the same way that mortgage advisors do - that way you don't have to type it each time. I just feel that where people potentially have a personal interest they should declare it.

So, using the same logic, i'm steering people to a competitor as well even though i've not named either company? As i say, i've never named my company on this forum and i won't, but i will name a competitor as their products are absolutely superb. They are http://www.soraa.com

My sole interest is to provide people with the right information so that they can see through the many traps and lies, make informed buying decisions and end up with LED's that will perform as advertised - as a large majority do not.

It is factually correct to me if I perceive it as brighter. That is what counts (to me) and that's what I wanted to say. Maybe the term "brighter" is used differently in a technical context, I and most people don't care.

When I try to read a book and with one bulb I have problems and with the other bulb not, then the other one is "brighter" to me. Period. I don't care if the technical term is "color temperature" or whatever, most people would describe it as brighter.
