Hey, I have always wondered what is an HMI? Like I know it's a light of course, but whats specail about it? Why is it used? What's the difference between lets say a 1.2 HMI and like a 1K light?
Any help would be awesome. Thanks

HMI is just a type of light. HMI is a beautiful high-quality light which has a colour temperature of 5600 kelvin and therefore produces a natural daylight temperature.

What's the difference between lets say a 1.2 HMI and like a 1K light?


What you are describing is the outcome power of the light. K stands for thousands, so 1K is equal to 1000 Watt. An 1,2K light produces therefore more lighting power than an 1K.

HMI is a very common standard in lightning, and you can use for whatever you want. Specially if you want to put colour gels in front of the lightning, HMI would be more suitable for the job than for example Redheads.

Just to clarify, an HMI is 4-6 times more efficient than a normal tungsten source. A 1k "quartz" consumes 1,000 watts and produces roughly the amount of light as any other 1k tungsten source. 1.2k HMI consumes 200 watts more than a 1k, but produces an amount of light closer to what it would take 5-6,000 watts of tungsten light to create. If your goal is to reproduce or balance to sunlight, then HMI are even more efficient still, as they do not need to be gelled (with light loss) to match daylight color temps.

hope that helps!
