Presidential BEEF, Difference of Light Technology

hi I have a beef with President Trump he made an announcement a while back and no no this is not a political video I'm not a politician and know nothing of a subject but what can I say I'm a simple man I see someone talk about electronics and I have to rectify it now to keep it simple he expressed his dislike of the new power efficient light bulbs and announced his new government support of the old incandescent light bulbs to increase their production he provided a few reasons such as people should watch with a light bulb I said history the lights no good I always look orange which is of course true because when the white light hits a surface the surface absorbs many of the wavelengths and only reflects a few which is why we see the surface in a particular color and so because he's orange he looks orange this is not a political video I'm just stating facts and science I thought he was joking at the beginning but then he completed himself by saying I always look orange and show to you the light is the worst ok then that's a different claim although if everyone looks different then no one looks different so that's not a real problem then he made another complaint about the lights but number two it's many times more expensive than that all incandescent bulb they have warnings if it breaks it's considered a hazardous waste site its gases inside which made me realize he's talking about CFL or compact fluorescent lights frankly I don't like those lights either so there is truth to his claims and you're kind of in the same boat this is not a political video it's not about if I dislike the President or not like him but you know how it goes you mentioned Trump and the whole world blows over that's why this video is only sponsored by my patrons at patreon.com although I may lose a bunch of them now because of this I shouldn't be afraid to talk about science it's just about science so spasm like now if you agree spasm is that how people like my videos by involuntary muscle twitch you think the only difference between light bulbs is light color and efficiency I created a table of many different parameters and I'll score every lightbulb to see which one gives the best user experience there are four different major types of light to check first one is the classic incandescent light there is a thin tungsten wire in there that heats up with electricity and glows the bulb is filled with nitrogen or argon gas pretty harmless you almost can't buy these in Canada anymore good second type is halogen its structure is very similar to incandescent just that it's filled with halogen gas which makes it run brighter so it's over 30% more efficient than incandescent they are typically made as spotlights but they also make them in these regular shapes too let me show you how see this they actually put a smaller halogen bulb in a bigger glass to make it look normal next is CFL or compact fluorescent light you have seen these big fluorescent lights in offices they figured out a way to spin them into this compact form there is mercury inside the glass that vaporizes and glows bright under high voltage mercury vapour under high voltage generates tons of ultraviolet light inside the glass is coated with phosphor that absorbs most of the UV light and glows in visible spectrum I'm not a fan of CFL light same as my comrade president Truong just joking and then there's the LED lights made of a bunch of tiny light-emitting diodes made of silicon that glow these are the latest technology my favorite and our markets are flooded with these good now all these can shine with different colors sometimes assisted by painting the glass and sometimes by different glowing material but for CFL and LED lights that make regular white lights used at home they can come in a wide temperature range of white the typical range is from 2700 Kelvin to over 6000 K with 2700 K being the warmest with most reddish tones same as incandescent or halogen to 6000 caving the coldest with most bluish tone used by more Moochie reason cycles enough talking let's talk some more and fill the table with the properties of my lights all these lights output a level equivalent to a 60 watt incandescent bulb power usage is simple I just write it from their boxes incandescent is 60 watts obviously halogen is 43 watts CFL is 13 Watts and LEDs 8.8 watts this is a bad parameter then less is better so I call it b1 light level for a 60 watt incandescent can be as high as 800 lumens but it's typically 700 or less lumens is the unit of luminous flux or the total amount of light emitted by a lamp for this halogen is 750 for my CFL 850 and for my LED is 800 lumens it's a good property the higher the better so I call it g1 length of life for incandescent is a typical 2,000 hours for halogen it's half that for my CFL it's 10,000 hours and for LED is 15,000 hours light quality in my opinion is about what the light is made of as in the spectrum and for that we need to do some testing so I got my hands on a special license or thanks to my friend Steve who helped me borrow it in other news he actually has a neck you know how digital cameras have 24 million pixels this one is a single pixel but it's a special pixel you know digital cameras can only see you red green and blue but this one sees every single color of the spectrum so using this we can see what every light is made of you might be surprised to know that even if the light color is the same it might be made of different light components so this is what we get we have a chart that's light intensity versus wavelength we get a little bit of UV light and then the visible range and then the rest is infrared first let me see if I can measure the sunlight I have to turn off all my lights here we go although it's a bit cloudy today so it might be on the colder side and you see it's not very smooth it's because the gases in the atmosphere absorb different frequencies of light and create notches in the wavelength and maybe I should stick it outside the window because the glass itself filters the infrared light it's a cloudy day anyway so there is not much infrared out in out in out it's interesting that the white light doesn't have a flat spectrum at all now let's try my four light bulbs starting with the incandescent light as my baseline this is my favorite light color it's warm and nice and here it is tons of infrared light but a very smooth peak that covers the entire spectrum Sun lamps on lamps on lamp so it's wasting a ton of energy radiating in infrared because we can see it anyway it might be just helping bees and snakes next light is halogen bulb and here's their spectrum very similar to the incandescent light bulb a very smooth peak nice and warm and has tons of infrared although the color feels a little bit colder incandescent incandescent halogen incandescent now to my least favorite light bulbs CFL although they did try to match the warmness to the incandescent light bulb and here it is whoo oh my god spikes spikes everywhere there is even a large spike in the UV region let's lower them there you go so the white light is made of three spikes three major spikes in red green and blue regions and the red spike is quite orange maybe our little orange guy wasn't wrong after all of course the CFL has a warm light I assume in colder ones the blue spike is much larger and so the spike in the UV light that's why I say CFL has my least favorite light quality because it's made of spikes like I said every surface absorbs a bunch of wavelengths and only reflects a few and that makes the color of the surface so if a surface reflects a certain wavelength that falls between these spikes it could appear too dark although it is not dark or if it matches these spikes it could appear too bright so although the CFL light has many spikes it may not light up the environment uniformly and it also radiates low levels of UV light that's known not to be great for health and now the LED lights first let's try the cold 500 K LED here we are no spikes in the UV region expected spikes in blue a much wider one in green and red region and then unexpected red spikes what are they using red LED lights let's try the warmer 2700 K LED Wow much smaller blue spike but huge red spikes let me just check a cold single LED light and see what it looks like there you go this is what I expected no red spikes these people might be using red LEDs to adjust their tone see the way white LEDs work is that they are actually made of blue LEDs and like CFL are coated with a phosphor layer the blue light goes through and some of it is absorbed by the fluorescent layer that glows in red and green spectrum it is not as a spiky as CFL light and creates close to no UV light let's try the IKEA warm lights there you go this is what I expected a nice and smooth peak covering the entire spectrum except for the blue spike that is why is philips using red LEDs I hate spikes oh just saw a report from the lighting Research Center of RPI stating that new phosphors are being developed to improve color rendering hmm so they intentionally added a red spike to make the light look better and philips is the newer technology I still hate spikes and think I hear of Sweden need a better job of emulating and incandescent light connection IKEA clips Philips psyche Afghanistan okay let's continue with the table for light quality incandescent is a 1 as the baseline halogen is very similar and is a 1 CFL has a very spiky spectrum and radiates low levels of UV that can irritate your skin if you see too close have sensitive skin or have a high UV level amp although newer technology can improve it but we still saw UV on this one so I give it half a score LEDs spectrum can be very similar to incandescent but it can still be spiky so I give it a point 9 for durability you drop incandescent CFL or halogen they can break and die but halogen is specially more sensitive halogen light capsule is made of quartz rather than ordinary glass to be able to handle higher temperatures touching it with your salty only fingers will significantly weakened it led on the other hand the cover is made of plastic it doesn't matter if it breaks as long as the electronics is not broken it runs so it's like 10 times better so if incandescent is one halogen is 0.75 especially for those that you can actually touch the quartz you just have to be careful not to shake or touch it CFL is also a 1 and it is much stronger but it's not that big of a deal you just have to be more careful with the other ones so I give it one and a half cost-wise I was surprised that the incandescent is around two dollars now used to be around loonie a maybe it's because they don't sell them much anymore good two and a half dollar for halogen $4 for CFL and LED is getting much cheaper around three and a half dollars for the dimmable option a dollar thirty cents at IKEA for non-dimmable option Sweden for light temperature incandescent and halogen are both around the same so one CFL and LED have a much larger range to choose from but who cares warm is the best option unless your cycle and don't forget blue light can create excessive glare and flare in human eye compared to red light especially dark at night when the eye pupil is wide open and can make it hard to see details so go on or go home it's good to have options but to me it's not a big deal I go straight for warm so I give them one point two four D mobility both incandescent and halogen or dimmable but CFL is not let's say 20% of the lights at home need to be dimmable and CFL can be used on the rest so I lower its score 2.8 LED can be dimmable but the price doubles so I give it a point 9 hazardous material is bad so higher score is wars both incandescent and halogen are made of class and inert gases glass breaks it can cut your finger so I give them both one CFL you can also cut your finger with glass but it's also made of the poisonous mercury so it's worse and I give it a one point three LED I guess you can cut your finger with plastic it's better but I'll give it a point 9 good now that our table is filled all normalized numbers by dividing every row by the value of the incandescent light for that role and this is the normalized table now calculate a consumer experience factor which I set it to be equal to the multiple of all the good parameters divided by all the bad parameters and so incandescent gets a 1 as expected halogen gets a measly point 45 all parameters considered it's only less than half as good as incandescent but CFL with all its imperfections is still five times better than incandescent still a winner but LED is 54 times better than incandescent ten times better than CFL forget about halogen LED is clearly way ahead of everything else for consumers nothing even comes close to LED lights this is what everyone should be using so back to our neighboring president he is clearly talking about CFL lights being bad with their poisonous gases and funky light spectrum but not only CFL is still much better for consumers than the incandescent we are well past that in the LED era not only switching back to incandescent is terrible for the environment because of much larger waste of energy it's 54 times worse than LED for the consumers I'm sure there are tons of other world leaders making terrible environmental decisions but if you have learned anything from the current pandemic is that our actions don't just affect us but each other everyone in the world should say no to excessive inefficient power consumption it's the scientific common-sense to save the planet so use LEDs please choose wisely for me this is not a political video
