Some things are forever.

Fire is still the best source of heat

The wheel is still the best transportation

firearms are still the best self defense weapons

Beer still beats water(or anything else)

Dogs are still mans best friend

Filament lightbulbs are still the best electric light source.

I won't either!

And your point is?

I replaced my swimming pool light with a color changing LED bulb. It cost $$$ a few years ago but it should be working long after I’m a dead guy.

Thank you.

I have used the coleman stove in tents north of 60 in winter and been warmer than in a house in Toronto.

I have been looking for a hand pump mantle light like th kind that were used on the farm when I was a child, The gas cannisters that power the mantle lanterns sold in the hardware store are considered hazardous household waste when empty and so have to be taken to the collection station along with old florescent tubes and those funny spiral ones.

I use a mantle light for outdoors and for emergency lighting in the event of a power failure.

My reading chair is next to a WINDOW....granted I live in NY state and the sun isn’t shining all that much in the winter...but you cannot beat natural sunlight pouring into your house. At night I want mood lighting......not a landing zone for a 747. Why do they need to confuse me with all these options?

Best=most perfect compromise of: practicality, reliability, simplicity, economy, efficiency, and most important...what I like best.

There is nothing more simple to troubleshoot than a filament lightbulb. No moving parts. No circuit board. No capacitors or semi conductors or anything. Just a filament in a vacuum. AMAZING!

They certainly have a large installed base...

reliability,

A "good" tungsten lamp lasts thousands of hours, any old LED lasts a hundred times longer. LEDs don't quit when you drop them, and they don't scatter broken glass.

simplicity,

The principles of operation are easy enough to understand.

economy,

As in low cost to buy? On a per unit basis, true, but it takes scores of tungsten light bulbs to provide light for as many years as a single LED lamp.

efficiency,

Only a small fraction of the energy that goes into a light bulb comes out as light, most of it comes out as heat.

and most important...what I like best.

No argument there!

You missed one, Tungsten lamps simply put out more light than an LED lamp. That's a big sales point.

There is nothing more simple to troubleshoot than a filament lightbulb. No moving parts. No circuit board. No capacitors or semi conductors or anything. Just a filament in a vacuum. AMAZING!

I'm not quite sure what good it does you know the filament is burned out. It's not like you can repair a light bulb!

As far as our eyes are concerned, nothing is wrong with lightbulb.

However, the problem is that all artificial light sources produce heat in addition to light. But fluorescent and LED lighting can produce same amount of light as incandescent bulbs but with less energy than incandescent bulbs. This because they don't waste as much energy in the form of heat.

You speak like an eco hippie what with all that conservation, effeciency and worrying about heat.

If we need more energy we build more plants and run more copper dangit.

And figure out a way to make organic diesel from jihadis.

Consider that incandescent lighting actually makes cooling systems work harder in the summer.

Yes, incandescents also help to heat a house in winter.

I look forward to LED lighting.

No. No repairing. You just throw away.

I think you don’t get it. When the light goes out(I’m talking about a vehicle not your dam house you nitwit) the first thing you do is check to see if the bulb is burned out. If it is, you throw it away and put a new one in.

If you have those damned LED nightmares, you don’t know what the problem is. It could be a faulty circuit board. It could be faulty wiring. It could be anything. You have to get a meter and start testing for voltage here and there. THen, if it is the LED/circuit board thingy, you have to pray there is someone somewhere with one in stock exactly like yours. There’s no standard LED setup. Every light is unique.

LEDs suck. Filament bulbs are the only way to go.
