I have a MUST SELL great deal! A 12k Sunray HMI Fresnel with Magnetic Ballast, all cables in perfect condition, scrim set in box, front cover, and a roller dolly. The kicker is it has a BRAND NEW never lit globe (a $1,000 Value!) I'm in North Hollywood and selling it all for only $3,000! I love this light, and the paint is good, no dents, the internals are good (reflector and wires are in great condition) and the glass is clean with no damage! It was barely used, just stored forever. Everything is included (But NO STAND). Below are more detailed photos. Please call me at 818-339-6933 or email me at firstname.lastname@example.org Thanks, Tim Alexander
18k = IMAX 15-perf (or 36K?) 12-13k = 70MM 5-perf 6K = 35MM 4-perf 3K = 35MM 2-perf 1.8K = S16MM 1.5K = 16MM 720p = S8MM 480 = 8MM I had to share this with someone. I found so many people including myself looking for these numbers I had to compile this list. I cannot find anything close to this on the internet all in one place. Digitally, IMAX is referred to as being three times better/larger than 35mm (18k / 6K). On Film, IMAX is three times larger then 70mm and 70mm is twice as large as 35mm therefore it should be six times as large. This is of course the best possible scenario of each format. These are all comparables, they cannot be absolutely perfect. I'm comparing category to category. So much in the real world changes these numbers, for example cropping 16mm to a release format reduces the frame size and corresponding resolution or finding a camera and lens that can shoot S8mm or 8mm and come close to 720 or 480 quality.
Hello everyone, I am a student of the Virginia Commonwealth University's Cinema department, and one of our Adjunct Professors is directing a short film as part of his MFA Thesis. The short is crewed largely by former and current students of our program, though the DP is a local professional. While crewing with our students was a non-issue for Grip and Electric for a long time, we have recently discovered that we will be using a 12k HMI, which is something I only have minor experience with, and none of the other team members have yet worked with any light larger than a 4k. As I have not worked with this DP in the past, I am uncertain of the extent to his knowledge of electricity. I figure he knows more than I do, but just to be safe, I want to cover my bases and learn as much as possible before we begin shooting this coming Monday. Currently, we have a 45KVA MQ WhisperWatt Generator at our immediate disposal. I have posted a photo of the specs below. After doing some math (to the extent of my abilities) and talking to a local gaffer (though I did not show him the photo), I have been given the impression that this 45KVA Generator should be sufficient to run a 12k and also support additional lights and power needs. This brings me to my first question: Does this Generator seem like it would be able to sustain a 12k, and still run a distro set-up with 3 100 amp lunchboxes additionally, or would we have to rent out another generator? Discussing with the team, we were at a loss as to whether the 108 Amp "Rated Current" (shown in the photo) refers to the overall output of the generator, or if each phase of the generator is 108 Amps. I realize that the two hots used to run the 12k would be taking at least 50 amps each (Is this correct? Also, I have not gotten a chance to look at the ballast, I only know that it is Magnetic, which I have never used before, and that the light itself is a CMC Silver Bullet. I do not know what the Power Factor is), so it would be best to use the third leg for powering anything else. Related: What are some pros and cons of using a Magnetic Ballast? Having only used Electronic Ballasts, I can only recall various tidbits I have read before: Magnetic ballasts are heavier, but don't break as easily. Are there any problems with Flicker that Electronic Ballasts avoid? The opposite? Finally: What special considerations must be taken into account when using the 12k? I have some experience with setting up 12ks, but only in the capacity of being an Additional Set Lighting Technician who was just following the orders of people much smarter than myself. I have never even come close to needing to know the ins-and-outs of designing a distro set-up to support a light greater than 4k. My plan is to run Banded from the Generator to the 600 amp Distro-Box, three lines of 100 Amp Bates to 100 Amp Lunchboxes, and two Hot lines and the Ground line from the Distro-Box to the 12k whenever it is needed. Is there any major flaw to this plan that I have overlooked? Any other advice that anyone would be able to give us would be greatly appreciated. I know that I have a lot of expansive gaps in my knowledge, and having accidentally stumbled into the position where I am the most knowledgeable member of a team using this intense of a setup, I really don't want to mess anything up. Thank you for your time and thoughts, everyone!
