  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Red has been the most disruptive element in cinematography in digital era. They forced giants like Canon and Sony to play catch-up and is still pushing forward. Now i believe there is a good opportunity to do it again in a complimentary area.

LEP - Light Emitting Plasma.

Arri seems to have put their Helios 270 in a hold-up to favor their latest LED technology the L7. And the only reason they are doing it is the lack of competition.

LEP is clearly a much more robust technology, has the biggest lumens per watt ratio, has a much more linear light spectrum distribution, it is 5000K which is perfect for digital sensors, consumes less power than any other technology, produces very little heat, and is durable. Obviously it will kill ARRI's HMI business, Tungsten Business, and LED will die before getting its feet on the ground.

If RED decided to come out with an intelligent, wireless controlled LEP light, they would sell year round and would force the old technologies to vanish.

Moreover, as a business, diversifying in a complimentary market would help RED maintain its financial health in moments where the market is saturated of cameras and R&D need more time to come up with something worthy of an update.

Jim, you gave us a way to capture light, now you can give us RED SUN.
 
While I agree that there's a lot of excitement around LEP lighting, I don't think we have gone all the way with LED technology yet. Better color and more consistent color has increased on the LED front recently. Red has stated that they have been working on a prototype LED unit, and I'm sure they are exploring other tech as well.

I would like to see more LEP options though as there's currently only 3 games in town and only one of those is packaged in a motion picture lighting unit. The technology isn't too crazy and both LED and LEP equipment could be fairly inexpensive to pull off.

I'm a bit shocked we haven't seen larger wattage bulbs in the world of LEDs. A single large 50, 100, or 200 watt bulb would be incredibly useful. Instead it's all about arrays and panels.

Hi Phill, I think you meant lumens per watt and not watt by itself.

I think it's both a limitation of the technology and a business model.

For one there is the die size limitation for the diodes: "Extraction efficiency (the ratio of produced photons vs. photons that actually exit the substrate) goes down significantly with larger die sizes. Maintaining equal current distribution also becomes more difficult, so current spread contacts must increase in area as well."

Another problem is that white LEDs have a very poor light spectrum that peaks on blues and greens and falls on reds, so even if they have solved the problem of the die size limitation it would still be a bad idea to have only one huge LED. That is one of the reasons they are going for panels with multiple mixed color LEDs, which has its own problems. The other reason is that they are trying not to cannibalize their other products.

I think LED have its use for small spaces like cars, or for practicals, like a microwave prop in a scene, but LEP renders a much "closer to the sun" light spectrum, thus giving us all the data to get noise-free, chroma-rich images.

LEP light rolling out soon - Game Changer
Luxim's innovation to the technology appears to be to use solid-state technology to generate the RF waves instead of the conventional (and highly electrically inefficient) magnetron

Luxim's Lifi technology has also been around for at several years now and hasn't really taken off for motion picture lights. If it is a game changer, it is a very slow one
 
Stay focused Jim.

Red has changed the game with Cameras and Lenses, why not with lighting?! And I don't think with only LEPs, it would be great to see some affordable RED HMI light kits.

Agreed. Also, in all these technologies, the spectrum's are not perfect, and require alignment to the sensors of the camera. The academy's research on LED is interesting, if anything though, it's one of these buyer beware type of things ... where any problem would create unfixable issues in post (LEP also has spectrum notches too). So whether it's LED or LEP, having RED light products I think would be very encouraging for the TV industry and Studio's who want to convert from old stuff because of the power and cooling savings. Another major market RED might want to consider is Reality TV, which often is in situations where having all these huge lights with gnarly power requirements is extremely impracticable.

Patrick, agreed on beware type of things for LEP and LED, there's still to much to be explored with these technologies, it would be great to see RED to dig in on lighting tech.
 
This sums up the differences and use of LED vs LEP. (besides color spectrum, color shift, and other technical aspects)
From the Lumix website:
"LED does have an advantage over LEP in its ability to scale down. If a job calls for a 3,000 lumens, the LEP system would still require an emitter, driver and power supply and would therefore have approximately the same cost as a 20,000-lumen LEP system. In this particular case, LED would be a more cost-effective solution because it scales down well. On the other hand, if the job called for a 45,000 lumens, LEP still has the same three components and similar cost. By contrast, for LED to scale up, the manufacturer would have to add more arrays of LEDs, bigger heat sinks and a larger fixture. In short, LED scales down well. LEP scales up well."
