LED vs. HMI. The color temperature of tungsten lights is around 3200K whereas the color temperature of HMI lights is around 6000K (nearly the temperature of sunlight at noon). Therefore LED can save money on energy cost. Tungsten (~ 3200K)Image via ARRI. Tungsten-halogen lamps. 2. Making this possible is the replacement of traditional tungsten incandescent bulbs with a number of other choices, including light-emitting diodes (LEDs) and xenon lamps. We are going to tackle the question which light bulb type reigns supreme? The main advantage of halogen lamps was their increased efficiency.A halogen lamp consumes around 20% less energy than an incandescent lamp within the same brightness. LEDs. However with LEDs things can be changed at a moments notice. What Does It Take to Join a Motion Picture Industry Guild. So there is huge value there. Available in standard Edison bases, these bulbs are used as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods. In the 21st Century, LED applications becomes more popular and mature in our daily lives, we can find many products are using LED technology e.g. The always insightful Ryan Connolly demonstrates how to create a DIY LED lighting strip. Remember to take into account that LEDs can be run through standard AC power sources or by way of batteries, so power consumption costs are very low compared to tungsten lights. To learn more about different types of lighting you can read: Let There Be Light – Four Common Types of Film Lights and for more information about remote phosphor LED lights, take a look at Shedding Light on … Tungsten light fixtures are also prone to failure when exposed to oils from human skin. Halogen and CFL bulbs are cheaper but also less efficient. You could choose LED, halogen, CFL, or tungsten. appliances, advertisement, toys, automotive ……etc. In the same LUMEN (~ 630lm), LED Bulb requires only about 7W but Tungsten light requires about 40W, the LED Energy usage is less than Tungsten light by around 5.5 times. Tungsten, HMI, Fluorescent, LED.Don’t forget that there’s another light available for free each day, the sun. quantitative polarisation studies and critical colour assessment in stained specimens—the white LED's spectra is atypical as a consequence of the exciting blue LED's output mixed with that of the phosphor's emission. Here will we focus on the lights you most often see on a film set. Taking notice of this, manufacturers have really been pushing toward bringing LED lights into the professional production market. Dimming of the light from 100% to 0% is offered by tungsten and LED lights, whereas the HMI supports dimming only up to 50%. Bulbs Traditional flashlights used incandescent bulbs with a tungsten filament that glowed in a gas-filled glass enclosure. LEDs are capable of producing a high range of light. If you are working on a tight budget turn your attention toward Yonguno, which has begun producing the YN160 LED lights – great lights and cost effective. Fluorescent lighting is heavy, complicated, expensive and really best suited for the studio. are inexperienced working with lights. On the other hand, Tungsten lamps become less popular than before. tungsten lights feature a tungsten filament housed within an inert gas, when a current is passed through the filament, the naturally high resistance of tungsten causes the filament to glow and output an orange light. The ability to do this cannot be understated. For example the ARRI L Series comes in tungsten, daylight and tunable white/color giving a production team a wide range of lighting capabilities.

An incandescent lamp generates light when electric current heats a tungsten filament wire so that it glows, or incandesces. There are many variables, so lets dig in! In the beginning, all we had was the standard, incandescent light bulb. Before LEDs, we lit our sets with HMI (Hydrargyrum Medium-arc Iodide), tungsten and fluorescent technology. 3. LEDs are often much cheaper (in price and, naturally, build quality) than tungsten, and won't heat up enough to require you to wear gloves to touch the light or its barn doors. on a budget, and 2.) Dimming. LED luminaires provide a strong punch of colour, while conventional tungsten units boost brightness in white and fill in the critical long-wavelength parts of the spectrum. Incandescent light bulbs are the oldest type of lamp. Other professional grade LED Fresnels can be found through Flolight or LitePanels. ARRI now offers some amazing LED Fresnel lighting options with it’s L Series. Tungsten-halogen lamps have a lifetime of 2000 hours and decay in brightness with time, but much less so than arc-lamps, making them a more cost-effective light source compared to arc-lamps. 4. Operation Temperature Types of Lights. In Behind the Scenes, Blog, Colorado DP, Denver Camera Operator, Denver DP, Denver Video Company, Denver Video Production by … However as I stated above, there are lower cost options for LEDs such as Yonguno and Flolight. Tungsten lighting produces a significant amount of heat. On LED lifetime is 15 times Tungsten Lamp lifetime. However these options are expensive. Lighting carries a great weight in film and video in terms of setting a tone and mood that directly effects the audience. Interfit Super Coolite 455 Twin Head Kit . LED lighting is much more temperature friendly and does not product the heat that a tungsten system produces. Let’s start by taking a look at the pros and cons of LEDs, fluorescents and tungstens…. The LED operation Temperature is around 60°C to 80°C , thus the LED operation Temperature is less than Tungsten light by 33 times. LED (Light Emitting Diode) technology has now developed to become a usable source of light in live performance and recorded media. The term ‘tungsten light’ refers to the most common kind of incandescent lightbulb used to provide artificial light to indoor areas such as your home or office. As the lamp continues to operate, the tungsten slowly evaporates due to the heat. Tungsten lights are very similar to the light bulbs you may have in your home, just much more powerful. HMI vs LED vs Tungsten vs Flo Light Tests. Check out the first part of Film Riot’s episode on LEDs and tripods. LED or halogen? High-performance LED lighting can achieve an efficiency of up to 17% or 120 lm/W, which is a huge increase over both traditional tungsten and tungsten-halogen incandescent bulbs. Interfit’s Super Coolite 455 fits the bill here; its bank of four 55w fluorescent lamps delivers a more neutral tone of 5200k. I was on a documentary film shoot recently that used these lights due to their portability and I came away from the experience incredibly impressed by their capabilities. Though LED and Tungsten are not the only two types of lighting units employed in film and video production (HMIs and Fluorescents being the other two big contenders), there has been a huge push by manufacturers of late to bring LED technology to the forefront as a major player, possibly even as an alternative to the tungsten arsenal. Halogen lights have been the preferred light source as a replacement for incandescent lamps for a long time. You can also safely plug 3 or 4 LED lights into one power strip, versus needing to have each tungsten light on its own circuit. The LED element is having high impact resistance and Non-friable LED is also recyclable for Aluminum material and Plastic cap is able for recycling production. LED Life Span (average) is between 15,000 – 35,000 hours but the Tungsten Lamp have only 1,000-2,000 hours. Efficacy of LED vs. Incandescent – Lighting efficiency is described in terms of “efficacy”, which is the measure of lumens emitted per watt of electricity consumed. Tungsten incandescent lighting emits a full spectrum light giving you and your client exactly what they would expect to see under natural … For additional brightness, take a look at the 655, which gives the equivalent 1320w output of tungsten lighting. HMI technology is way too expensive and not quite as reliable as LED lighting since they are not solid state. The average life-span of a tungsten light is around 1,200 hours, while the average life-span of a LED light is right around 50,000 hours. LED light sources have by far the longest lifetime and their brightness does not decrease with time. Two additional things to keep in mind when comparing LEDs with tungsten are life-span and color. Safety Regarding to point 2, the operation Temperature of LED is around 60°C to 80°C while Tungsten lights’ operation Temperature is around 2000°C to 3600°C, therefore the LED is more … This feature enables the filmmaker to control the brightness or the output power of the lamp. In the past when working with traditional tungsten lights, my crew would have to wear leather gloves to make any lighting adjustments due to the high operating temperature. Standard incandescent light bulbs have efficacies of 10 to 17 lumens per watt. LED lighting Rotolight The average life-span of a tungsten light is around 1,200 hours, while the average life-span of a LED light is right around 50,000 hours. Over the years, advances in technology have brought about innovations in how to light our homes and commercial buildings. This means the lights become dangerously hot when in use. While most productions still use the traditional tungsten or fluorescent light kits, LEDs are becoming more and more of a real option for filmmakers. Safety In the same LUMEN (~ 630lm), LED Bulb requires only about 7W but Tungsten light requires about 40W, the LED Energy usage is less than Tungsten light by around 5.5 times. Keep in mind though that these lower cost solutions wont give you the same light quality as the ARRI L series kit, but they are satisfactory for most applications. Therefore LED can save money on energy cost. Incandescent When finalizing your outdoor lighting or pendant selections, it's important to figure out what type of lamp you'd like to go with. Now we have compact fluorescent lamps (CFL) and light emitting diodes or LED for short. In addition to the range of light, the mobility and operating temperature of LED lights is something that cannot be ignored. Life Span (average) Two additional things to keep in mind when comparing LEDs with tungsten are life-span and color. This LED light bulb uses only 9 watts of energy, saving up to $56.10 over the life of the bulb vs. its incandescent equivalent (based on 3 hours/day, 11 … LED bulbs have a higher up-front cost but save you money long term. The advantages of using LEDs against Tungsten lamps are below: 1. One of the widely cited advantages of tungsten and remarked on in the article above is that the typical single emitter white LED is less suited for critical work e.g. The LED production does not need for any nitride and Sulfur dioxide which it is good for the environment. LED fixtures have some advantages over ‘old’ tungsten based instruments and are particularly attractive to the events and concerts market right now. So there is huge value there. In this style LED bulb, clusters of LEDs are covered by a lens which spreads the light over a wider area, like standard incandescent bulbs. Also, keep color foremost in your mind when picking out or looking into LED light kits as the cheaper kits have a tendency to cause color spiking. Tungstens are still the most competitively priced in terms of professional grade lighting solutions. LED Technology is based on full solid state light, unlike Tungsten light. Having said this, though, solid-state luminaires continue to get brighter and more spectrally complete. Here is a nice introductory video to the ARRI L Series LED Lights by Clearhead: One area where LEDs have been playing catch-up is with price. A good thing to remember is that a regular 1K tungsten light is measured at f/8.7 at a distance of 8 feet with the camera set at ISO 800 and 1/50 s for the shutter speed. Tungsten lighting is heavy (LED lighting instruments are far more lightweight) and energy inefficient, requiring high wattage and converting more energy into heat than actual light. 4. We’re going to help you compare led vs halogen, CFL, and tungsten. A traditional ARRI Tungsten 5 piece Light Kit with run you around $3,000, while one single ARRI Tungsten LED light with run you around $2,000.
