Just occurred looking at these that they have a pretty constant light
output in all directions - unlike most LEDs which have a lens focusing it
in fairly narrow beam. So pretty similar to an ordinary filament lamp.
There's a few occasions when I'd like LEDs like this, but haven't seen
them on sale in the component suppliers. What should I be looking for?

Sandpaper.

ps I bought a set of lights from B&? last year (filament I admit) but
1/3 of the lamps have already packed up.

I bought a set in woolie's sale the other week and they're already dying.

But for 70p...

I bought some spare LEDs from Wooleys. They were 6p for a pack
of several (somewhere between 6 and 10 - can't recall now).
Tried them when I got home, and they're blue (at least, the
first 2 were). Must admit, I did wonder why you'd want spare
LEDs -- now I know.

I did once buy some axial LEDs which radiate in all directions
except along the axis. They were from a radio fare. Never seen
them since. I presume they were for making up light strings.
(Axial LEDs which emit in one direction are easy to find.)

Wide angle LEDs

No - those are still far too directional. I want something with a light
output pattern similar to a GLS lamp. Ie, all round with the exception of
the cap.

Yes it can work., I filed one down past the lens once but the surface
needs much polishing - noit worth the effort really.

The christmas ones seem to have a conical hole for a lens.
If you can accurately drill into the end, you might be able
to create the same effect.

Generic name is "inverted cone" or in big LEDs "side emitting"

Thanks for that. The ones I was looking at seem to have what looks like a
sphere round the electrodes - then the whole lot encased in a transparent
tube.

Flame polish them. It won't be optically perfect, but you explicitly
don't want that...

....you can also do them tens or hundreds at a time.
