Anyone found a decent brightness LED light? I just bought a couple that said 90W equivalent, but they compare better to a 60W bulb, but at least they look well made, some are flimsy plastic and fall apart when you screw them in.

I'd be a bit suspicious of these from the specs it says wattage 90W.

it doesn't say equal to a 90W bulb. Wattage would, imply that it's using 90W have you measure the bulbs actual wattage ? via voltage X current.

I assume you're looking at the top in the "item specifics" table, I wasn't. Further down it says "Replacement Halogen 90 Watt", but just underneath it says "Lumen 650-900lm" which is that of a 60W incandescent.

Nobody seems to know what Ebay means by "wattage" - half the sellers put in the power consumption and half put in the equivalent. It'd be better if they all put in the equivalent, as some LED lights are more efficient than others. It's the output that matters when choosing one, especially as most LED lights are dimmer than a 40W bulb!

I think I'll buy one of those corn on the cob shaped ones just to see what it's like. Looking at the specs they appear to be no more efficient than a compact fluorescent, but who knows? At least they'd give a more even light than the one above.

I've found Megaman CFLs very good. I'm using both golf-balls and some of
the spotlight R series. OK, you don't get instant light, but after 3 or 4
minutes you can't really tell the difference. Excellent for fittings that
are on for 6 or more hours.

Spotlights are rubbish, lights facing upwards are rubbish. Half the lumens are eaten by the wall or ceiling.

Unfortunately the LEDs flicker. The only non-flickery bulb I've seen is an incandescent, so I don't think energy saving bulbs are for you, unless you can find one with a decent power supply.

That would be a guess too? Or do you think all walls etc are the same

10W tend to be about 75W filament equivalent.

The brightest well made ones I have seen to date at 1080lm

Costs the same as you paid for two. I have been caught out a couple of
times by nominal LED 60W lamps being much brighter than the CFLs they
were bought replace. Not sure if this is because CFLs dim with age.

ISTR There is a brighter one available in E27 fitting.

I can't be bothered with Amazon, they have a ****ty webpage I can't find anything on that looks like a kid designed it, and no proper feedback system, and are usually more expensive. They charge sellers about twice the commission of Ebay.

WHAT?!? LEDs are nowhere near as bright as CFLs. It's a new technology that's nowhere near as bright as what they say they are.

ISTR There is a brighter one available in E27 fitting.

I just bought the very last 270 LED corn shaped one in the UK on Ebay. It states 1500 lumens, which is just above 100W equivalent. It's an E14 fitting, but I've got so many ****ing adapters now I can fit anything into anything.

I have a couple from Toolstation, part no 14618 (also available as an ES
version), which have proved very bright (12W / 1050 lumens), approaching
100W equivalent as I perceive them. Not cheap, although the stated life
expectancy is impressive (35,000hrs) so they might even be reasonable
value. A vast improvement on CFLs, in my opinion, so that has to be
worth something.

I'm a little puzzled at why the light output isn't even broadly
proportional to the wattage for LEDs though: I wanted a '60W'
equivalent for a smaller room and thought a 9W version would do it, but
the stated light output (450 lumens IIRC) was less than half the output
of the 12W.

There are so many different LEDs that they use, some seem more efficient than others. The best efficiency seems to be CREE LEDs. But I've gone off those, they are very hot and don't last.

I was in Ikea the other day and overheard some beardy weirdy looking for
a particular wattage LED bulb (and of a power way over anything they
had.) It seemed to be based on trying to find something X times brighter
than one he already had and involved some confused number mangling
involving both power *and* lumens to arrive at something like 16W.

The fact that only half of them bother to write lumens on them?

Anyway,
40W incandescent = 400 lumens
60W incandescent = 700 lumens
100W incandescent = 1400 lumens
Pretty easy to give a correct equivalent instead of lying don't you think? Two LED bulbs both rated 60W equivalent are never anything like each other. Yet two 60W incandescents are always indistinguishable.

It's not watts versus lumens. It's showing you what to expect from standard tungsten bulbs. It's relating the power consumption of a tungsten filament to the light it gives out.
