Default Re: Lamp Limiter Bulbs

The "Antique" filament bulbs are quite interesting in their own right. They are made to look like early 20th century light bulbs - some even have a pip on top. Various styles are available with BC or ES caps. Poundland have been selling them for £1 though they're not always in stock. Other shops have them too, but usually more expensive.

Here's one I bought from Poundland last year. It's a 60 watt ES "Antique" pip-top bulb - I also bought a BC version of the same design. It uses a real filament, but despite being rated at 60 watts, the light output is fairly low. I'd say it's more like a 25w traditional bulb. The glass has a yellow tint which probably reduces the brightness somewhat. It does consume around 60 watts as measured by a Maplin power meter.

As well as being useful for lamp limiters, these bulbs could be used in a display of vintage radio and electrical items. They certainly look vintage even though they're not.
