SBC LED < 40mm

Well, that's wrong for a start. It just has to fit through a 40mm hole. It can be up to 100mm long.

SBC is a common car connector, so quite a range of car type lamps in LED. But I assume this fitting is mains?

Look at the Poundland 3W ones, they are quite directional due to their pyramidical construction.

bare live bits

That's not a problem since the bulb is totally enclosed. It's not as bright as I would have liked, but it's definitely a contender.

This one is 37mm diameter, I just measured it...

...I've had one for over three weeks and it hasn't failed yet, unlike the 'LED filament' type it replaced which lasted a week.

Cheers

What inside a globe? After al any socket ith no bulb in has live bits. Brian

Thank you very much. I think that's the leading contender right now.

They're epoxy encapsulated, so no live bits. I have a few of the 12v bi-pin type.

I found plenty of SES/E14 mini-pygmy LED lamps (fridge replacements) on ebay but no SBC/B15. Sorry

If you go for a "filament" pattern LED candle - they are almost completely omnidirectional (I use them as replacement for the cooker hood SES tubular bulbs).

e.g.:

they do have some 40W equiv ones coming in June:

They measure at 42mm diameter, for the SES/E14 types. Possibly same for SBC, dunno.

Be prepared to pay for ongoing replacements. They don't do the mileage printed on the box, but still IMO give out a good light.

You could carefully break the bulb (it's glass) and run it naked inside your globe? That would do better for cooling it.

Won't fit, then.

That's a possibility.

I spotted a rather interesting error in the following:-

Description

The new LED Pygmy from Lightwell has been designed as a direct replacement for the incandescent miniature Pygmy light bulbs. Rated at only 2 watt it produces a light equivalent to 25w, offering an extended lamp of 45,000 hours life compared to the incandescent alternative. Ideally suited for use in fridges, freezers, sewing machines etc.

The 2W non-dimmable pygmy LED light bulb is a direct replacement for a standard incandescent pygmy lamp.

This bulb saves up to 80% on energy usage and is available in a choice of Warm White and Cool White colour temperatures. Connection is achieved through a Small Bayonet Cap (SBC) B15 cap.

Warm White produces a gently glowing, calming white with a slightly yellowish tinge. For example, this kind of light is ideal for offices, classrooms, intimate settings like restaurants, or hospital wards.

Cool White emits a brighter form of white ? totally monochromatic ? ideal for modern, minimalist interiors with clean lines or with stunning block of primary colours.

/ENDQUOTE/

It was the final paragraph that caught my attention, mentioning as it did, " ? totally monochromatic ? ". Whoever wrote this advertising copy, clearly has no understanding of the meaning of the word "monochromatic" since it literally means "of just one colour"! :-)

Quite obviously, the copywriter was fumbling for a "technical sounding phrase", as advertising copywriters tend to do in order to impress and bamboozle their valued customers (aka, valued resource) and didn't bother to look further down the list to discover "panchromatic" which could have neatly been rounded out with yet another "technical sounding phrase", "to a CRI of 85% or better".

I don't think the author of the above advertising copy is really suited to working in the marketing and advertising industry - too sloppy to the point of squandering opportunities to further impress the advertising world's target demographic.

Interesting. I generally skip through when there is too much text. If it can't be said in a few plain words, it's usually fluffed up bullshit.

Probably learned from the fashion of calling B&W TV monochrome. When of course true white is actually a combination of all the visible light spectrum. Which is why LEDs don't produce a decent white.

Also have to laugh at a 2 watt LED being of any use other than decorative in a room. And an LED producing 2.5 times the light of tungsten? Only with a very inefficient type like a pigmy. Which you wouldn't use where light is actually needed.

I have a couple of those in SES/E14. They do actually produce a very pleasant light. The globe is glass, rather than plastic, and the light output is uniform. The ones I got are warm white.

Big Clive demolished one for review a while ago.

FWIW, I found a 5.7W "warm white" sort-of "squat candle" in B&Q this afto for £4, so bought one. It looks great. Thanks for all the input guys.

(No, I didn't go in there for that, but had a quick look while I was there. The drill bit sets were reasonably priced, too, but had screwdriver & masonry bits in them which I don't need.)

At mains voltage? LEDs run at a few volts. I've got a very large (I was going to write huge) LED "corn" shaped bulb which has 150 volts DC on it for many many LEDs in series, but it's current limited for the LEDs, so it just tickles.
