My thumbs will fall off if I answer that. I sort of answered in another response you can read about Dark Bastard Amber (Rosco 03). Power Factor is why it’s stupid to ban Halogen’s and why LEDs are not as efficient as has been claimed. A Halogen bulb has a much higher CRI and power Factor of 1, a cheap LED has a Power factor of half of that (.5). That means the cheap LED uses twice as much current as the Halogen and can’t come close to the Halogen’s CRI. In commercial applications ( Like a stadium, for example) the power company charges on Kva demand and charges extra for Power Factor. That’s because in real energy terms and on a commercial building’s bill, a building full of cheap LEDs is way more expensive than the light it provides should be. So they often have to install capacitor banks on commercial buildings. And the LED needs just as much or more copper (Wire gauge/ breaker capacity) as the Halogen. All for a much shittier quality. Sure, encourage the USE of LEDs, go for it. But that old Twaine quote applies here: “don’t ban steaks for men just because babies can’t chew them”.

For years I did work for events that had an audience, stage video recording, Imag and a couple times even film. Rosco 03, with an absurd amount of light and power. You can beautifully white balance the cameras and display and it looks great and matched to an audience in a dark hall. I like to pair R60 and R51. If you’ve got the circuits, add some lee 202 .5 correction, but careful not to lose white balance in scene changes… Does anyone actually use gels/poly anymore? I moved on years ago to commercial AV installation. I assume it’s all LEDs now right? The last time I did stage lighting was 2005. My memory might be failing me here, so if the colors sound crazy, I’ve probably forgotten or mixed up. I have actually designed a bunch of installations using LEDs (S4, ETC, etc lol). The technology we are discussing is ancient history now right?
