Light Bulbs | LED vs. Incandescent

Jun 04, 2021
Hello, in this video we will see the

light

bulbs

. The market is interesting at the moment, at least in Denmark, where there are more opportunities than I remember. This is due to new efficient technology and the banning of old and inefficient technology and some solutions. between I will explain why LEDs are so efficient compared to

incandescent

light

s and I will verify the advertised wattage of the

bulbs

, which is not always correct. I can also find time to mess around, but first let's look at the difference between

incandescent

s and LEDs, we have two here. large decorative bulbs, one of them has full power and consumes about 40 watts, the other one is timid, if I turn it on, it still only consumes about 7 1/2 watts, but it emits much more light, why is the LED much more efficient?

There is a clear difference the incandescent bulb is hot to the touch the LED is not incandescent the light actually works by heating a small metal wire until it glows red hot due to thermal radiation. We may not think about it every day, but the harder things become, the more they radiate if they are hot enough, it is a glow visible to us, for example, a flame or a wire heated by a flame, the heat in The wire excites the electrons by pushing them into higher energy orbits around the atomic nuclei when the electrons fall back to a lower energy orbital. and its energy is converted into photon light.

More Interesting Facts About,

light bulbs led vs incandescent...

The metal wire of an incandescent bulb typically heats up to thousands of degrees. Therefore, it is made of tungsten. Most other metals would melt at this temperature, but where does the heat come from? There is no flame inside. Bulb tungsten is not the best conductor and the wire is also very thin, so it has the highest resistance in the electrical circuit. The filament wire is therefore a resistor and its resistance causes friction for the electrons passing through it. This friction generates heat like when you rub your hands together. LEDs, on the other hand, do not work by heating a wire instead of ink and LEDs emit light by electroluminescence.

Light-emitting diode is a semiconductor that has a negative side with excess electrons and a positive side with holes. Missing electrons When the correct voltage is applied to the semiconductor the electrons flow from the negative side and merge the holes on the positive side, this releases energy in the form of photons of light. No heat is needed, but even an LED will get hot when using the operating temperature inside the semiconductor. Typically the temperature is 60 to 80 degrees C, much lower than the incandescent bulb wire and this explains why LEDs are much more efficient. It takes a lot of energy to heat anything to thousands of degrees, only about 2 to 3 percent of the electricity is converted into light from old light bulbs the rest is lost to heat hence incandescent bulbs for home lighting are banned or are being banned in many countries.

The incandescent bulb on the left is illegal to sell in Denmark. I generally hate saucepans, but looking at the specifications I have to admit that it makes sense that there would be a problem, although I recently had brunch at a local restaurant and noticed that the cold cuts looked less than delicious, it was illuminated by LED bulbs with a reproduction index poor chromaticity. Seeing our eye is a measure of how well colors are seen. When illuminated only by the bulb, not all bulbs emit light or make all colors appear natural. 100 is the perfect score and incandescent bulbs are very close, but many LEDs struggle with color reproduction.
Let me try to show you. I'll use the Danish beef. called holy pizza, repeat after me holy poser antis with these free bulbs which are quite similar except for the color rendering, this LED has a rendering index above 80, this auto LED is above 90 and the incandescent bulb is about 100. I film each bulb with a The camera locks at exactly the same setting, so the difference in the free recordings is just the bulb. Here is the side by side comparison. Notice the color difference on my monitor, the one in the middle is an ugly yellow-green, the one on the left is much better, but the right one looks the best for a meeting and a white plate.
I'll let you choose which one, if any, looks more delicious, but for the table. I highly recommend bulbs with a high color rendering index. LEDs also need electronic components integrated into the bulb to function. To operate, the semiconductors require direct current and not alternating current from the mains. If the electronic components are poorly designed. The LEDs may flicker a lot. It's not easy to film, but hopefully you can tell which of these two flickers more in real life, not cropped at 25. frames per second, the one on the right has an annoying strobe effect and the electronics don't like excessive heat , so LEDs are not suitable for Amon lights.
This incandescent bulb is rated at 300 degrees C. There are no electronic components to melt, speaking of special bulbs, they sometimes get hot. It is exactly what you want, the heat radiation is infrared radiation and this bulb is designed to keep baby animals like chickens and piglets warm. The bulb is tuned to give off a lot of heat and this pig will soon sense it and start venting. Did I mention these infrared? Bulbs are also great for the buffet to keep food warm, like bacon and pork chops, are you okay piggy, okay let's move on. I think it's time to quickly show and test some of the most special bulbs I found.
These are the large decorative bulbs from before they were advertised at 7 1/2 240 watts, let's try it the silver device is the wattmeter and the top number shows the wattage, the 40 watt incandescent consumes 37 watts a little low but that's okay, the two LEDs are closer to spec and consume about seven and a half watts, they take a little time to warm up so let's move on to the spec sheet with the final readings. Here you can really see the differences in the two technologies with which I have marked the not so good specifications. the color red for a quick overview because we are going to expand with more bulbs to take decorative bulbs to a new level with complicated glass shape.
I know it's backwards but this is just a test set, apparently a 40 watt incandescent bulb uses about 10 more and less than advertised. How about a 40 watt LED? This is mainly for industrial use because at 3200 non-dimmable lumens it is not cozy, but it is surely a 40 watt bulb for reference only. I will show a comparison with a 40 watt incandescent decorative bulb, yes, it looks like normal cozy lighting, let's try the other one, well, it's cozy lying on the beach with sunglasses on the way, let's move on, this is an example of a light bulb that will be difficult to find in the future.
Incandescent bulbs with clear glass, apparently tinted glass models will be allowed longer in the EU, while Zarb clear glass incandescent bulbs and halogen bulbs were also supposed to be phased out, but so far the ban has been lifted. delayed by about 70 clocks each. they consume a little power but halogens are even more efficient and the endless decorative box options, well that's the summary so far, just a few more left to try now, the next bulb is fluorescent, the one I use in my light boxes for video lighting. a large one advertised with 125 watts and a CRI over 90, however the specs may not be very accurate because it only uses about 50 watts.
I guess that's a way to save energy, rendering the light bulb useless. Look how they advertise now, this is real energy. Its power rating is a plus as it only uses six clocks to output over 800 lumens and the power is very accurate even from a cold start, this board was a little different because it was the only one that started with higher clocks which advertised and only fell out after a long warm up the final bulb is the very popular 400 watt halogen work lights. It can consume a lot of electricity but emits about nine thousand lumens.
This one is a little weak at 368 watts, so here's the final summary. I hope you liked this video and liked it enough to click the "Like" button which would make me very happy. My next video will be something different. I visit a fellow Danish youtuber and mess up some of his stuff and I have to say safety first because then we shouldn't do this at all, it's a bit dangerous and I'm actually a bit nervous that we'll punish him. He will not wear a crown. Here's a little bonus for sticking it out to the end. Look at the advertising. on this one on the front it clearly says anti insects and insect repellent on the back it says it attracts less than white light English is not my first language but it repels and the song list is not exactly the same, thanks for looking.
