HMI has never quite felt like real sun to me; even 18k fresnels. They always feel like reflected sunlight, like off of a building window. HMIs have inconsistent color, and not quite a full spectrum. "Close enough" for most, but not quite. The best is a large tungsten fresnel; 5k,10k, and 20k frensels on a soundstage coming in through a set window. It really does look and feel like sun. The infrared heat they project is very similar to the sun, and it helps actors feel their light as they move through a set. I've never seen an LED that comes close; they just don't have the spectrum in the longer wave lengths where it really matters most for skin tones.
Agreed... Used the 20 k tungsten fresnel two months ago. It looked incredible. But wow the amount of electricity use is not sustainable at all. I'm wondering how long it will be before we can get this light quality with LEDs... I think it's close to be honest. Maybe 2 years?
@@davidographer 100 amps per leg in the grand scheme isn't that much. You're just running one 220v whip to the light, and on a soundstage, it's not much for the power system. Same for any 500A tow plant. As far as LEDs coming close...probably never. The cooling needed for a COB would be gigantic, and the optics needed to spot and flood a chip that big would be impractical. Mole has an LED 20k, but it is not the same. Comparable maybe, but not the same. Also, I think with large lamps like this the IR heat isn't always a negative. Many many actors have commented that they miss the warmth of tungsten. I'd say that alone is a good reason to use them still. If they can help talent give a better/more authentic performance, that's enough for me.
This is a completely UNFAIR comparison. You don't even need to turn the light on to know that an open-face lamp will not have a clean shadow. YOU SHOULD COMPARE WITH A 6K HMI FRESNEL. Par lamps are not meant to give you a clean shadow but punch. They are intended to be used far away (the shadow becomes much cleaner) or through fabrics as well as bounced.
Agreed. It was more of a spontaneous test. Loads of clients have asked me to go direct with some m series. Couldn't really find any videos out there to show what's they do direct so I just threw in the video.
Well to be fair, he also showed the Aputure light with its reflector dish. And that was also better than the reflector style Arri light. If you really care about shadow sharpness at higher output, the Dedolight 1200D HMI focusing head has shadow sharpness on par with a bare 60watt LED if not better.
This is cool as hell. Thanks for all info David!
Awesome! Thank you for this.
Thanks Luke! I'm a big fan!
Great practical tests, super useful!
Would love to see the Evoke 2400B on that mix as well

the t12 looks so much better
Great Video
How much of that finger is still on there?
Fresnel...freSnel!?!? No. Otherwise, great vid and thanks for sharing your findings :)
Solid info. Video should be half this length, realistically even condensed to 60 seconds.
Yes this is the truth. I'll cut it down and make a short I think. I also will probably do a more interesting test next time
Fresnel is pronounced Frin - nel, after it's French inventor Augustin-Jean Fresnel
Great knowledge 😂 parley fransay?
I also just love that the french always invite all the silent letters they can to every word 😂
You butter? 🧈
its actually pronounced: "FUR-NEL"
Just a note that the "s" in Fresnel is silent. It's pronounced fruh·nel.
Muhricaa sux indeed. A gaffer told me that recently 😅 110 v BS

120v in America 😢
