This is NOT A POLITICAL VIDEO!!! I'm a simple man... Also regarding Halogen light bulbs, it seems in countries with 240VAC they are designed such that their life is same or better than incandescent. In 120V of north America almost all I can see for halogen is half the life of incandescent for same power rating (make sure lamps run on same voltage and light output when comparing). In any case, I filled my table per my local values for my lamps, and some per my taste. you can always adjust the table values to your local numbers and taste and recalculate. LED still will get top point. and who cares if halogen scores a bit higher WHEN LED IS WAY HIGHER ANYWAY! and remember... THIS IS NOT A POLITICAL VIDEO!

The glass you broke on halogen is not for aesthetics only. Halogen bulbs have a tiny possibility of violently exploding. That's why every halogen lightbulb has double glass. In case of floodlights and car lamps, the second glass is part of the lamp. Spotlights, 'power saving' lightbulbs, etc. are double glassed for more than aesthetics.

LED lights vary in lifespan too. Most LED "bulbs" overdrive the LEDs, making them heat up, reducing efficiency and lifespan. Underdriven LEDs, say doubling the number of LEDs for the same output, will use less electricity and last longer

Thanks for the normalized table which confirms my growing esteem for LED bulbs. Memo: In a microwave oven, only incandescent should be used for the CAVITY lightbulb (an LED will quickly fry). For an over-the-range nuke, LED bulbs work great on the underside for range/countertop illumination.

I've been lucky with all the microwaves I've put LEDs in. From my observation most bulbs are installed outside of the active area of the megnetron, separated by a mesh then encapsulated with sheet metal to manage RF emissions. Though I imagine some microwaves will have the bulb inside the active area to save on manufacturing costs (I imagine putting the bulb inside the wave guide behind the plastic sheet)

18 years ago I replaced all the incandescent bulbs in the house I had just moved into with CFLs. After *nearly two decades* they're finally starting to wear out. Safe to say I got my money's worth out of them, and saved a boatload on my power bill. They served their purpose, but about 1/3 of my house now uses LEDs and that number will grow as the CFLs gradually fail. I swapped my truck's headlights for LEDs too and love them. I will say that I haven't found a "warm" LED that comes anywhere close to the color temperature of an incandescent or CFL. Admittedly I haven't bought a bunch of them to compare, but both brands I have tried skewed more brown than orange/yellow.

you just explained to me exactly why I hated fluorescent lights, the light always looked wrong and hollow to me... for years I stuck with incandescent because it just looked real. I swapped to LED, and found that some LED lights irritated me due to the pulsing nature of their light, I used a 1k fps camera to catch it, but the light wasn't steady on but rather ran at around 60hz (coincidence maybe?) My favorites are the ones I constructed myself on DC circuits to avoid the flicker factor that some LED bulbs once had

LED lighting has come down to a reasonable price so I am phasing out the others, although I might use the occasional incandescent light as a dummy load in electronic experiments, but that is out if the real scope here. Also, LED's can be used without the need of class 1 wiring, i/.e. the basic electronic component with an appropriate ballasting which can operate easily with as little as 5 volts D.C. which at times can serve to avoid dangerous voltage in some places whewre that is particularly important and/or convenient.

Now let's thinlk some more everywhere about "let there be light", and those led's which are encased in plastic.

I would love to know your opinion on how much color temperature of light affects your mood and energy levels. I found these awesome color and temperature adjustable smart bulbs at a liquidation store I have been using for many years now, and I have Google home routines set up so that in the morning the lights turn on with an even WHITE color (Red+Blue) to help you feel energized and refreshed, and more like natural light outside, and then in the evening at sunset, the lights will dim to 30% and move to a much warmer tone to help you feel relaxed and give you that nice warm light. I think it's a killer setup, and I have noticed in myself that with the white light during the day I feel more awake and alert vs when I used to just have normal warm light inside all the time. Love your videos man, been watching for years and years, keep up the fantastic work and fighting the good fight to keep people well informed on important information like this. Cheers mate!

I guess you would be glad to know, when I moved into my current home, I replaced all CFLS, tube fluorescents and incandescent lights, with LEDs. I also replaced all lamps, outdoor lights, my fridge light, stove light and so on, with LEDs. The only lights I didn't switch to LED, were my oven and my microwave. I don't know what my modern microwave uses, but I'm pretty sure I can't use an LED in my oven. However, I would love for them to come out with a better option that makes LED look at bad as incandescent light. The only thing I like about CFLs, is being able to salvage the toroid magnet. The only thing I like about incandescent, is using them as a cheap heater that puts out light (but I have no need for heaters).

honestly, you're doing an amazing job at telling people how they are wrong. honestly, the required spectrum (and frequency) of a light source _will_ determine the type of source being used. you just need a desktop lamp to read some papers? use LED. need to do stuff in a workshop with rotating machinery (more or less in sync with the network frequency)? use incandescent or LED or a combination of all these ; even FLs on all three phases will be confusing. Need to do some painting or work with tiny electronic components? Then you need a smooth, well-distributed spectrum. Need some lighting in a bathroom, that also needs some IR so it feels warm? Then you can either chose LEDs and add some IR heating to complement them, or instead just use standard filament or halogen bulbs, as these might just radiate the right amount of heat and light to suit your use. There is no "right light source" for any use, it really depends on the use and in what conditions things are being used. Making things such as incandescent lights unlawful will not save the world ; people need to be taught to use the correct device for the intended purpose.

LED is like 99% of the consumer market now here in Europe.

They had valid reason to at the time, this isn't an argument, when technology is premature it is premature. I know its fun to imagine they were just being stubborn but early incandescent were not like the modern kind, and the electrocution risks during early electrification were no joke at all, the "boom" was real. While 60 watt equivalents are decent now with LED, 100 watts are still fast burn out junk, and neither have economical 100 cri equivalents yet in fact no where near 100 for the sale priced junk. The people who complain about people not using leds are the same ones who go on plane trips to prove how worldly they are, a single trip is likely dwarfs the ecological costs of not replacing every bulb with led, and that's without looking at the hidden ecological costs enabled by these things being made in china..

I have two situations where I use cold lights: in my bathroom mirror and as optional lighting of my workbench. Both of them have same reason, in more cold light it is easier to see details

Never really stopped to consider how spikes in the visible spectrum blend to us, but don't reflect the same way as a more evenly distributed mix of wavelengths. The differences in how we perceive light and sound waves is so damn interesting, the way our brain fools us into looping the color spectrum with purple, the way most of us are so much more particular when it comes to detecting simple ratios between sound wavelengths vs. light wavelengths etc.

Hi Mahdi, about the light temperature there is more to it that what you said, the warm color(2700K) won't interfere with your sleeping cycle much, but the daylight color(6500K) temperature makes you awake and increases your focus, so if you read before bed, you should use warm but for example in a library you should use daylight for better focus, but warm is not good for designers and artists who need to see the right colors, the daylight temp would show the more accurate colors.

You could probably reduce the amount of plastic on LED "globes", or heck even use paper to spread the light. I would say that glass could still a lot worse if its in terms of the overall environmental impact. But truth to be told, both are just as bad if you don't take into account the environmental/repurposing factors in production.
