Mole LED Tener on Phantom - any flicker issues?

Sean Emer
 

Has anyone used the larger Mole LED sources (the 900w 5K equivalent or the 1600w Tenner) for Phantom work? I'm going to be shooting around 1000fps, and want an f/8 on top of that, so looking for right around 4,000FC on the products through diffusion. I know 5K tungsten fresnels would suffice for this, but if the LED models are flicker-safe then it'll save us a bunch of headaches with heat on the plastic products and power consumption/distro. I understand that the phantom flex 4k will actually come in around 930ish fps at 4k, not an even 1000, and I've heard some phantom techs say that the LED Tener is safe, while others have indicated it could be a headache. I'm shooting Thursday and have no time/budget to test. I'd love to hear if anyone has experience with this!

Sean,

 

Luminys has a 1200 watt Table Top LED light that will give you 11,000 FC at one meter.  Guaranteed not to flicker even when dimmed.  Three of them were recently used (two with a big soft box) with a 1,000 fps Phantom for back stage reaction shots at the Oscars.  This is the link.

Hi Sean,

I have not used the Mole LEDs but I am very curious about them.

I was on a food job where we used Arri Sky Panels at 500FPS with no issues. I think we also used them at 1000FPS, but I'm not 100% sure. Sorry, we were all over the place with frame rates, three cameras (2K Flex, 4K Flex, Red) and four sets. I don't remember seeing any flicker. Perhaps someone else can confirm that.

I've been on jobs using AAdynTech Punch Daylight LEDS @ 1000FPS. Those are good and a nice light quality. Mixed well with daylight.

I have used Arri M6 and M9 HMIs, with the Arri high speed ballast. But even those can flicker, occasionally. Get an extra HS ballast, or two. Sometimes replacing a flickery ballast with a different HS ballast works.

Yeah, the 4K Flex tops out @ 938FPs, or something like that.

Hope that was helpful.

Plasma.  Have only seen/attended demos - not shot with them - but the esoteric technology of plasma lighting is the ideal bedfellow in this scenario.  Fresnel focus/throw, fresnel levels of output, practically zero heat radiation.

In L.A. http://hivelighting.com/rent/ seems to be the outlet.

I used Arri Skypanels recently with the Phantom 4K Flex at 1000fps and no flicker. We had five of them for a tabletop sized shoot for thrree ads. The firmware on the panels has to be version 3 or you will get flicker. With version 3 you're good to 48000 frames a second. But at a 1000fps they're not the brightest of lights even with the diffusers taken out. I was mostly shooting at 2.8 or 4 and that was with two 120's on the background, a 120 overhead on the subject and two 60's at the sides. Also had a Digital Sputnik for specular highlights.

Sean, 

One of our clients recently did a head to head test with the Mole Tener against our Nila Arina.  The Arina was delivering double the light at the measured distance of 40 feet and used half the power. The Arina draws only 800 watts and most people are using it to replace a 2,500 watt HMI.  The advantage to Nila for your high speed shoot is that we are flicker free through the whole dim range tested to 5,000 fps and all Nila products are flicker free at any frame rate when they are on at 100%, we have tested this to 1,000,000 fps.  Our LED fixtures are used by hundreds of reservers and industrial clients for their high speed filming needs.  http://www.nila.com/highspeed-lights/
