The tube in the fluorescent light over my workbench in the cellar has
failed. Before buying another (T8 36W 4ft) I thought I'd look into a
new LED-based fitting of similar size. I've looked at the TLC, Ikea,
& Wickes but not found anything. Am I imagining that such a thing
exists?

It appears they do:

http://www.bltdirect.com/4ft-led-t8-tubes-1200mm

Though quite how an 18W tube saves 80% of the energy consumption of a
36W is beyond me.

I'd check the lumens too as I am exceptionally suspicious of all this
"equivalent" nonsense.

This LED one:

http://www.bltdirect.com/4ft-led-t8-...6w-alternative

says 2000 lm, but a Wickes fluorescent:

http://www.wickes.co.uk/Wickes-4ft-3...-Tube/p/162293

says 3450 lm.

I smell a rat.

Aren't the LED tubes 'directional' so potentially all the light would
be going in one general direction, rather than disappearing off into
the roof space / whatever (I think this might have come up here a
while back)?

Therefore, the 'effective' light output in the required (uni)direction
might be better than the light from an a generally omni directional
fluorescent tube, assuming the more scattered light isn't better for
overall illumination etc.

Go to banggood.com. Keep an eye on the mains safety details before buying.

depending on what you are doing in the workshop, when they were discussing going LED here the subject of rotating machines came up and how some LED lights might cause problems, and would need special diffusers fitted to reduce or ellimminate possible flicker.

Are there diffusers that add persistence then and in any case I
thought most (so not discounting 'some' of course g) LED lamps ran
from fully rectified DC so there shouldn't be much flicker in the
first place?

Interested to know for the new workshop lights (around the lathe).

Directional lighting.

I got one from aldi And checked the output against a fluoro and it was
similar.It starts a lot quicker.

Fluoros were notorious for the same thing.

Is this due to the directionality of leds, perhaps. If you measure the light
from a tube from all around it will be higher as its omnidirectional.
I still find the normal tubes seem better to most people who use them at
the moment though they may well be less efficient.

That's what I thought. I don't have a lathe or any big/fixed power
tools, just handheld ones.

Go to banggood.com. Keep an eye on the mains safety details before buying.

I hadn't heard of that site before, but there's a lot of weird,
interesting stuff. Thanks.

Bangood are pretty reliable, sometimes shave the price on an item by checking it on ebay. dx.com are similar , both have a limited range available from EU warehouses for faster delivery.

For bench lighting , TS no brand T5`s are a good value4 option

Thanks for all the advice, but when I saw the price of a new
fluorescent tube I just bought it.

Took it downstairs, swapped it in, thought "it's not coming on --- if
the ballast is bad I'll be miffed!", then realized I'd taken the
starter out to stop it from flickering.

Those which ran at mains frequency, yes. Modern high efficiency one run at
a much higher frequency. Perhaps 30,000 Hz.

LEDs are basically DC devices. So don't follow the on/off cycle of the
mains. Some are pulsed, as this allows a longer life at high output, but
don't think this applies to many domestic ones.
