Energy saving linear halogen

The "technolgy" is called "marketing hype"

They're digital.

Bill

One way..

thinner filament, runs hotter, more light per watt

shorter life.

ROFL!

True - its either "on" of "off" - That's digital :-)

Given how very inefficient even 'halogen' is, can't be impossible to increase the light output. Probably by running the filament at a higher temperature. Which will also shorten the life. Thus killing two birds with one stone.

Your assumption that the light output is the same may not be the case.

However, the efficiency is better. The old one will be a D rating (or E rating if it was long life). They now have to be C rated.

There are a couple (at least) of technologies for improving the efficiency. The first one is to coat the inside of the tube with an infra-red reflective coating which reflects some of the heat back onto the filament. The second one is to use a different gas in the tube. The long life versions no longer exist.

That's binary isn't it?

Bill

Binary implies a counting system "on" or "off" isn't really a counting system.

There are 10 people in the world. Those that understand binary and those that don't.

Digital implies a quantized as opposed to an analogue system. All binary systems are digital. Not all digital systems are binary. We count in base 10 - that's digital. Nothing to do with binary being a counting system. Some storage systems - notably the cheaper end of the SSD market use 8 or even 16 analogue charge levels to encode 3 or 4 binary bits of information per cell in order to increase capacity. The mechanism is digital, not binary.

There is onlyone way to increase the efficiency of any filiment lamp. That is to run it hotter which increases the visible light output. This reduces lamp life unless something can be done. Maybe adjust the amount of halogen in the tube?

And what is a non linear Halogen then?

Brian

Ordinary bulb-shaped one, like a car headlight bulb. The linear ones are about 5 inches long and a quarter diameter - like a miniature fluorescent tube.

linear

"standard"

There's more chlorine halogen. From the Greek chloros for green so it's greener.

Well, its not my assumption, its a claim made on the packet.

Thanks to you (and others) for posting technical explanations.

A friend who used to work for the Broads Authority habitually used the expression 'linear waterway' to mean 'river'.

Bill

I suspect he included canals in his definition.
