Even if it\u2019s possible to use natural light up to a certain point, nothing beats dedicated lighting systems for fiability and consistency of light quality.<\/p>\n<p class=\"\">Some use consumer lightbulbs, other use contruction site spotlights, but even if it\u2019s possible to get good results, a lot of limitations were felt :<\/p>\n<p class=\"\"><!--more--><\/p>\n<p class=\"\"><em>As always, a full list of the articles in this blog can be found <a href=\"https:\/\/kinolios.com\/en\/blog\/index\/\">HERE<\/a>.<\/em><\/p>\n<ul class=\"\">\n<li>If you work with LEDs, the CRI (Color Rendering Index, a scale of 1 to 100 permitting to judge the rendering of colors against a perfect light source, like the sun) is often low or inadequate. Consumer grades LEDs and fluorescent will often have a color cast, either magenta or green, difficult to correct. Good CRI LEDs exist, but they are still quite expensive.<\/li>\n<li>You can use halogen or incandescend bulbs, as the CRI will be very high, but the color balance will reduce it\u2019s usability, as most are 3200 Kelvins or lower. If you work with natural light, which is approximately 5600K, you won\u2019t be abled to achieve a neutral color balance.<\/li>\n<li>Using construction site spotlights can result in a wide and difficult to control beam of light. It can be somewhat mitigated by constructing barndoors, but it\u2019s still not optimal.<\/li>\n<\/ul>\n<p class=\"\">If you plan to do small documentaries like I do, renting equipment can get expensive real fast, especially if you do small shooting sessions during a long period of time.<\/p>\n<p class=\"\">Then the only solution was to take the matter in my own hands and create the light suiting my needs. Before settling on a Kino-flo style light, I though about making a LED projector. The problem was the same as consumer grade LED bulbs, as high power good CRI LEDs were expensive, and creating a reflector for it would have been hard.<\/p>\n<p class=\"\">A HMI light is in theory possible to make, by using ballasts made for HMI horticultaral lamps. High CRI HMI bulbs can be found for relatively cheap. Here again, making a suitable reflector would have been the hardest step. There was also uncertainty about the quality of the horticultural ballasts, if it would create flicker or change in the intensity of the light.<\/p>\n<p class=\"\">So I chose to work with fluorescent tubes. You can find really high CRI ones (&gt;98) for about 8$ for a 120cm length. They have the advantages of being easily swap-able and can be found in either 3200k or 5300k color temperature, adding flexibility to the light.<\/p>\n<p class=\"\">My specifications were:<\/p>\n<ul class=\"\">\n<li>That the build was cheap<\/li>\n<li>Daylight balanced light, or near 5600K<\/li>\n<li>High CRI<\/li>\n<li>Compatibility with standard cinema stands.<\/li>\n<li>Possibility to light only 2 of the 4 tubes at a time. This way, I can use 2 3200K tubes and 2 5600k ones and change color temperature at the flick of a switch. By using 4 of the same tubes, it can divide the light intensity by 2, adding flexibility again. (It would have been possible to make all 4 tubes dimmable, but the ballasts were much more expensive and I don\u2019t know how the CRI of the tubes will be impacted while dimmed)<\/li>\n<li>A silent light and without flickering<\/li>\n<li>A reflector and barndoors to control light spill<\/li>\n<li>A sturdy frame and construction to survive transport and shooting conditions<\/li>\n<\/ul>\n<h4 class=\"\">THE construction:<\/h4>\n<p class=\"\">I chose plywood as my working base. Using sheets and wooden batten planks is easy to work with and inexpensive. The tubes need a starter and a ballast, but today there exists electronic ballasts which take care of both. Contrary to old magnetic ballast, they don\u2019t produce noise and shouldn\u2019t flicker, using a 20.000Hz frequency.<\/p>\n<p class=\"\">I chose two Phillips HF-Performer HF-P 218\/236 TL-D III 220-240V 50\/60 Hz ballasts. Both control two 36W tubes. These ballasts could be found for 20$ each online.<\/p>\n<figure id=\"attachment_24639\" aria-describedby=\"caption-attachment-24639\" style=\"width: 1920px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-24639 size-full\" src=\"https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1.jpg\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1.jpg 1920w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1-500x281.jpg 500w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1-1000x563.jpg 1000w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1-200x113.jpg 200w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1-768x432.jpg 768w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/BLOG_KINO_1.9.1-1536x864.jpg 1536w\" sizes=\"auto, (max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-24639\" class=\"wp-caption-text\"><em>Photo of the ballast.

Now to see if it passes the test of time and shooting conditions, but I\u2019m confident in its construction. The light, even without additionnal diffusion is already really soft. The 5300k color temperature helps produce a slightly warmer tone to the skin tones, which is helpful.<\/p>\n<p class=\"\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-24841 size-full\" src=\"https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3.jpg\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3.jpg 1920w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3-500x281.jpg 500w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3-1000x563.jpg 1000w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3-200x113.jpg 200w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3-768x432.jpg 768w, https:\/\/kinolios.com\/wp-content\/uploads\/2018\/08\/RESULT_1.2.2_1.2.3-1536x864.jpg 1536w\" sizes=\"auto, (max-width: 1920px) 100vw, 1920px\" \/><\/p>\n<p class=\"\">The total cost was about 120$ even a few hours of work. Even it the tubes are delicates, they don\u2019t cost that much, especially compared to Kino-flo ones! 4 tubes at 1800lm, plus the help of the reflector make it a quite powerful light, easily usable as a keylight.<\/p>\n<p class=\"\">The real Kino-flo still has a lot of advantages. It\u2019s less massive (well I\u2019m sure I could have built a smaller frame, especially the edge of the reflectors which are wasted) and weighs less (a Kino-Flo with it\u2019s ballast weights 7,2kgn while mine is 8,5kgs)<\/p>\n<p class=\"\">Once I have the opportunity to test it on a real shoot I\u2019ll make new posts about it. I think I\u2019ll add diffusion at the edge of the barndoor to create en even softer light.&nbsp;<\/p>\n<\/div>\n<p class=\"\"><a href=\"https:\/\/kinolios.com\/en\/blog\/index\/\"><em>Blog index<\/em><\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Ce premier post de ce blog se portera sur la cr\u00e9ation DIY d&rsquo;un projecteur pour une utilisation sur tournage.
