50 bucks each. Last time I looked they were $80, and I gave them a miss
then.

Weirdly, I can buy a double tube 3' covered fluorescent light for less
than that.

I agree wit your $10 comment,

presuming that the chart is correct!

Or have I missed something here?

I figure they will need to come down to under $10, and people may start replacing them.

When you can grab a 2 pack of the old style at Bunnings for $4.90, people won't switch in a hurry, even if it represents
a good power saving.

I'm not convinced that they are worth it even if the cost does come down
to the same price as a new traditional tube. Most of mine have lasted more
than 40 years now, so what is the point in a led replacement ?

It isnt, it's a pack of lies. You don't replace
conventional tubes every 4.5 years.

> Or have I missed something here?

Yep, that that chart is a complete pack of lies.

Even at the same price as the conventional tubes, bet they don't,
essentially
because they last so long. Some of mine have lasted 40 years now.

Even the ones used every day generally last 20 years.

** Did you see the data sheet?

https://asksteplight.files.wordpress.com/2014/06/corepro-t8-led-20w-data-sheet.pdf

The suggested application is for covered car parks, warehouses, coldrooms
and signage - situations where the tubes would be on for 12 hours a day or
more. Interestingly, the major users of 1.2m fluoros (ie shops, offices and
work places) are not mentioned.

Homes that have 1.2m fluoro fittings use them mostly in kitchens and
bathrooms where the light is cycled many times per day - doing this reduces
the life of a normal fluoro to a small fraction of the quoted 20,000 hours.
However, it will not do the same with LED tubes and combined with flicker
free starting and being unaffected by low temperatures is enough to justify
using them.

Plus most LED tubes are made from polycarbonate so are practically
unbreakable.

Also watch out on the lumimous flux. Further down the page they admit
that it's lower than for a fluoro, but attempt to make that seem OK by
observing that the emission is more directed.

Well, maybe, but my fluoro is under a white ceiling.

Bullshit. Mine cycles less than twice a day in the kitchen and not at
all in the bathroom which doesn’t have a long tube fluoro in it.

- doing this reduces the life of a normal fluoro to a small fraction of
the quoted 20,000 hours.

Bullshit.

Trivial to get that without paying anything like that.

Mine are completely unaffected by those.

I've never broken one of mine. And it
costs peanuts to replace if I ever did.

You will have to look a little deeper than that....
There are on the inside.

I installed one in the kitchen a number of years ago, and don't recall
seeing them, but then the memory fades with time

They are located inside the unit.

I wasn't doubting what you said, I just didn't remember connecting it

That would be because you did NOT connect it,

I must have. because I replaced a conventional fitting with a flouro

it was/is already wired.

It was already wired in the fitting. So you did not wire it.

My cellar/workshop has one 4 foot flouro fitting which cost less
than $5 with tube. There is another light, a 23W spiral CFL that
fitted into an existing fitting (the CFL cost just $2).

Maybe we'll have to buy LED replacements in ten years or so when
current flouros expire.. because they'll be the only thing on sale
by then.

Bet they aint.

Any predictions?

That they will be around for as long as anything else, essentially
because they are so common in non home situations.

Or maybe your iWank wearable technology will have eliminated the
need for room lights

Just another of your pathetic little drug crazed fantasys.

Another ad-hom,the only resort of a brain-dead fool.

Nope, statement of fact.

Only in your tiny mind.

Mine cost about $27 from memory. Yes, a no-name brand from ebay.
I'm amazed at the amount of light it produces @ 13W.
My eyes can detect a slight amount of flicker, though.

why would LED's flicker? something to do with poor ac to dc conversion?

More likely no real cap on the power supply which is basically the same
thing.

You don’t need to connect it, it comes preassembled and all
you have to do is connect the mains to the terminal block.

yes I know. but I didn't remember doing that

I meant the terminal block for the entire light fitting, not the ballast.

You must remember connecting it to the mains unless you really
have fried what you have between your ears with your whacky weed.

Seen them at ALDI $13 for 4 foot ones

I tested with a lux meter and they were almost identical at one foot.
so you have some then? I have some edison LED bulbs. they are ok in
desktop or bedside table lamps, but pretty well useless as ceiling lights.

Bullshit, I have replaced all the 15 watt CFL ceiling lights in the
house with 7 watt LEDs, the light is far better and they come on
instantly. Also replaced a 32 watt flouro in the kitchen with a 15 watt
LED fitting which also gives far better light.
That's my experience as well. LEDs beat the piss out of every other
form of lighting. In some of my smaller rooms, I only run 2W globes,
as I do in the hallway and desk lamps. Most others are 3 and 4W around
the house, and are more than bright enough for me. I also have a 13W
1200mm 'fluoro' tube, which is almost too bloody bright for the
kitchen (kitchen also has a 4w globe in a down light). Even my fridge
has a 1w LED globe.

the planet thanks you..

So does my wallet. Aside from the white cane I needed to buy to get
around the house... err, only joking.

You'd lose that bet.

I tried some LED screw in ones in ceiling fittings. they do not
illuminate the room like flouros or incandescents do. they don't seem to
disperse or 'throw' the light

Hmm. As I progressively changed my CFLs to LEDs, I was always mindful
about light levels. I couldn't see much difference, other than when I
went to really low wattage LEDs.

No idea. I'm sure I can see the 'tube' flicker a bit though. Maybe I
should use the word 'strobe', as in watching movement under the light.
