WEBVTT 00:00:00.400 --> 00:00:06.480 Plasma. It's the most common form of matter in the universe. Yet, many of us 00:00:04.480 --> 00:00:09.920 don't see it in consumer products, unless it's in fluorescent lights, neon 00:00:08.400 --> 00:00:14.160 signs, or those little lightning ball knickknacks you can get in the mall. But 00:00:11.840 --> 00:00:18.320 what exactly is this stuff? Well, plasma is similar to ordinary gas, but the 00:00:16.080 --> 00:00:21.840 difference is it's been ionized, meaning that the individual atoms or molecules 00:00:19.920 --> 00:00:25.439 in the gas have been given an electrical charge by applying an outside energy 00:00:23.519 --> 00:00:29.439 source to it, such as heat or electromagnetic radiation. Because 00:00:27.599 --> 00:00:33.040 plasmas are energized in this way, their atoms can emit light by a similar 00:00:31.039 --> 00:00:37.520 process to lasers. You can learn more about how energized atoms give off light 00:00:35.120 --> 00:00:41.680 in this video. But unlike laser light, which relies on additional equipment to 00:00:39.280 --> 00:00:45.440 form a narrow beam, many plasma light sources are useful for illuminating 00:00:43.200 --> 00:00:49.200 large areas. Whether it's a warehouse filled with fluorescent lights, a city 00:00:47.280 --> 00:00:54.399 lit by a lightning bolt, or even the entire Earth, since the sun also uses 00:00:51.600 --> 00:00:58.719 plasma to produce light. But a new crop of plasma lamps has opened up a whole 00:00:56.399 --> 00:01:02.480 new use for plasma light and is stealing headlines in the photography world. For 00:01:00.640 --> 00:01:05.600 someone like me, proper lighting is extremely important. Whether I'm 00:01:03.840 --> 00:01:09.040 shooting an episode of Linus Tech Tips or still photos of our team members in 00:01:07.439 --> 00:01:13.200 the office. And getting my lighting setup exactly right can be a bit tricky. 00:01:11.680 --> 00:01:18.479 Plasma lamps though are trying to mitigate problems that have faced photographers and cinematographers for 00:01:16.240 --> 00:01:22.479 years. One big issue that we regularly contend with is flicker. You see, all 00:01:20.479 --> 00:01:26.880 artificial light sources flicker to some degree, including popular HMI flood 00:01:24.640 --> 00:01:30.400 lights widely used in the film industry, often due to the alternating current 00:01:28.560 --> 00:01:35.680 that powers them when you plug them into a wall. And even though a typical 00:01:32.479 --> 00:01:38.320 flicker rate of 120 times per second or 00:01:35.680 --> 00:01:42.079 120 hertz is imperceptible to the naked eye, it can be a huge problem when 00:01:40.079 --> 00:01:46.000 shooting in slow motion or at a very high frame rate, as the camera will 00:01:44.000 --> 00:01:49.520 easily make this flicker visible. Plasma lamps though attempt to solve this 00:01:47.280 --> 00:01:53.680 problem by converting argon gas into a plasma. Because of argon's chemical 00:01:51.680 --> 00:01:57.520 properties, it flickers at such a high rate, hundreds of millions of times per 00:01:55.680 --> 00:02:02.079 second, that the light it produces is flicker-free for video shoots in absurd 00:02:00.000 --> 00:02:06.320 frame rates that can expose flickering in other light sources like LEDs. Plasma 00:02:04.640 --> 00:02:09.759 lamps are also more neutral in color than many other kinds of bulbs, not 00:02:07.920 --> 00:02:13.360 unlike direct sunlight, which tends to illuminate everything without giving any 00:02:11.360 --> 00:02:18.800 noticeable color shift. Although lights like CFLs and LEDs often give objects a 00:02:16.239 --> 00:02:23.280 slightly green or magenta shift, plasma lamps are full spectrum so that the 00:02:20.640 --> 00:02:28.000 colors can be filmed very accurately. And because plasma lamps use radio waves 00:02:25.840 --> 00:02:31.520 instead of heat to produce their light, they're also very power efficient, 00:02:29.760 --> 00:02:35.920 especially important since many kinds of professional lights are notorious energy 00:02:34.080 --> 00:02:40.000 hogs. So, if you are serious about shooting video or even stills, plasma 00:02:38.239 --> 00:02:43.599 lamps might be a good idea for you, especially if you don't want your boss 00:02:41.519 --> 00:02:46.800 to freak out about the power bill. Speaking of plasma lighting, Hive 00:02:45.360 --> 00:02:50.560 Lighting, they're a leading plasma lighting manufacturer based out of the 00:02:48.560 --> 00:02:53.920 US for all your production needs. They have three different fixtures that can 00:02:51.920 --> 00:02:57.280 be used in many versatile ways, from theater production on stage to the 00:02:55.599 --> 00:03:01.280 lighting we used for this video. The Loss, which is our fixture of choice, is 00:02:59.280 --> 00:03:06.640 one of the most low power draw lights I've ever used, coming in at a mere 273 00:03:04.959 --> 00:03:11.040 watts and giving me the output of an incandescent light that could easily 00:03:08.400 --> 00:03:16.480 draw six times more power, which makes it nice on the office power when I 00:03:13.120 --> 00:03:16.480 accidentally leave lights 00:03:16.519 --> 00:03:23.760 on. Is this thing on? That's actually still not okay. I don't care how 00:03:20.959 --> 00:03:26.720 efficient it is. So, thank you guys for watching.
