 The LED light bulbs removes a whole spectrum of life enhancing wavelengths.... e.g infra red and near infra red etc... 
It's cheaper because because you are getting an inferior product. This is no different from saying your box of cereal is cheaper when they substituted it with cheaper harmful ingredients and a smaller box.

You just got scammed and walked away thinking you had a win. This is how fiat works. 
 This is something I have not heard about before, can you share something regarding it for me to read/watch/listen to? 
 Well the older bulbs (incandescent) would output a more visible natural light that has wavelengths similar to the sun. If you google led fluorescent incandescent and sun light and click images you will see the the difference in outputs. Sunlight being the best and incandescent very similar.

The saving in watts is because led and fluorescent lights have sharp limited wavelengths. Our eyes haven't evolved properly for this so can irritate or sometimes cause damage as pupils will dilate or constrict accordingly or may fail to do so as it is not getting its appropriate input. (Some sunglasses can be damaging due to this)

Our skin uses light also and some believe our organs using the more deeper penetrable wavelengths. Repair etc

Think plants also.

But for just visual sake, it is much better to have a broad balanced light spectrum as opposed to a few sharp concentrated waves.

A better idea is just to do your calculation on an incandescent 60w on today's wages (or ounce of gold)  vs the past.

We have made things a bit better in some areas like automotive travel being more efficient so maybe an interesting calculation is how many hours of wages (or ounces of gold) to travel 60 miles vs the past.

If cars have become more efficient due to technology, has society benefited? Or was this stolen through inflation? Try find cars with similar brake horse power. 
 I think this is partially true.

LED’s are just efficient showing only wavelengths you can see.

Traditional halogen and incandescents are just controlled tiny fires. Most of the energy is wasted in heat rather than visible light.

I wouldn’t say LED’s are an inferior product based on that. 
 Correct
Like a noisy hot engine with wasted energy.
In this case though we are getting unwanted excess which can be a detriment. So this is a much better example of tech giving us  everything we got before and only cutting what was considered totally useless (unless you like the sound of loud v8s 😁

The difference..

The heat caused from the resistance in the tungsten filament with the flow of electrons is similar but the warmth is of little annoyance maybe sometimes welcome but for our discussion we are only considering the visual spectrum at this stage.

The loss of the overall balanced spectrum from not using an incandescent and its Smooth output would be a loss of quality.

Cars function if built better can provide same distant with same watts and no impediments.

If we could build a light source with the same amount of lumens and the whole visual spectrum we can do a better like for like scenario.

Eating rice is definitely more efficient if we only consider macro nutrients against eating steak milk and fruit... but we are dismissing any vitamins and minerals that would much be better to have in our diet.

Sorry for the dumb examples
Great discussions here on nostr and props to the thread originator for getting us thinking. 
 I believe the higher quality LED lights with high CRI and R values solves a lot of this with quality of light.

This full spectrum lighting would only really be useful for grow lights and current LED grow lights are designed to have those wavelengths for photosynthesis. 
 Yeah I mentioned plants further down.
We could also carry cri torches around also to further efficiency...

Listening to 32/96 kbit/s music would be more efficient as opposed 256/320 kbit/s

I would prefer and enjoy the higher rate though.

Likewise I would prefer an environment with less of a synthetic like spectrum as I could do without the irritation and headaches but sadly energy consumption is expensive and obtaining incandescents are getting harder.
