I feel like the film industry is big enough you should be able to engineer and market a special, non-flickering, tuned spectrum LED light that produces 80-90% less heat, and as long as the TCO isn't like an order of magnitude higher, you'd have a gangbuster success.

High CRI, tunable color balance and temperature LED lights are very widespread in tv/movie/commercial shoots and have been for years...

[saalweachter]

Do you happen to know if the lights everyone tells stories about -- both this news article, and other anecdotes -- are already LEDs, and still absurdly hot, because more light is better?

[kuschku]

The LEDs only reach up to 800W in the case of the SkyPanelX, while regular halogen lamps are still needed for more focused, higher brightness lights (which go up to 18kW per lamp(!))

[saalweachter]

Yeah, even with the 4:1 lumen:watt advantage for LED bulbs, that's still a nearly 6x brightness advantage for halogen.

Is the limiting factor the technology to make a 4500W LED bulb in the same form-factor/focus as the 18kW halogen, or does it just become prohibitively expensive to do so?

[kuschku]

LEDs produce 80% less heat, but they also fail at much lower temperatures. Which is the major limiting factor for LED brightness today, as the cooling solutions get larger and more esoteric the more power you concentrate in an area.

LED lights can be made small, flat and portable which is good for TV (e.g. for news reporting).
