What are HMI lights used for?
HMI lights are used to light outdoor settings. So, on high-end movie productions, you can expect to see HMI lights being used when the production is shooting outside. Usually, HMI lights are used on high-end film and television productions because of their price.
What type of light is HMI?
Hydrargyrum Medium-Arc Iodide (HMI) lights are the most used type of light on set. HMI lights emit an ultraviolet light with a blue hue. To power up, HMI lights require an electrical ballast. The ballast ignites the metal-halide gas and mercury vapor mix in the bulb.
How many lumens is an Arri M18?
Highly energy-efficient HMI gives you 92 lumens per watt Adjustable from 20° to 60° beam angle, the M18 can also be used with 1200 W bulbs. In design terms the Arri M18 is an open-face fixture that combines the characteristics of a PAR and a fresnel.
How bright is a HMI light?
Most HMIs are typically named after their wattage, so an M18 is an 1800-watt light, just as a K5600 Joker 800 is an 800-watt light. That isn’t to say that every HMI with equivalent wattage shares the same output. Different brands use different technology to get more out of the same amount of power.
How hot do HMI lights get?
around 5600 K
With HMI bulbs, color temperature varies significantly with lamp age. A new bulb generally will output at a color temperature close to 15,000 K during its first few hours. As the bulb ages, the color temperature reaches its nominal value of around 5600 K or 6000 K.
Do HMI lights get hot?
The brittle nature of an HMI bulb means you can’t move the light while it’s on. They get hot, which makes them hard to handle. There’re also fragile and take around five minutes to get up to their correct temperature.
What causes an HMI bulb to explode?
Lack of Insulation at the Base of the Bulb When the base melts, the gas stored in the bulb can leak out. The leaking gas causes a pressure imbalance which can result in the light bulb exploding.
How many lumens is a 1.2 K HMI?
The Arri M18 1.2K / 1.8K Watt HMI Light is an open-face, lensless, efficient lamp head. It was built to work with a new power class of lamp — the 1800W and 1200W SE HMI. These have an average life of 750 hours, a luminous efficacy of 92 lumens/watt, and a Color Rendering Index (CRI) greater than 90 at 6000K.
What is a joker light?
K5600 manufacturers of the Joker line of portable, well designed hmi lighting kits. The leading manufacturer of compact HMI lights for location lighting. Lightweight, yet rugged, Joker lights have become the standard on film and video crews for documentary, ENG and commercial production.
When did HMI lights come out?
History. In the late 1960s German television producers requested lamp developer OSRAM to create a safer and cleaner replacement for carbon arc lighting used by the film industry. Osram developed and began producing HMI lamps at their request.
Do LED lights smoke when they burn out?
Just the other day, one of the LED light bulbs in our kitchen short circuited. It made a huge popping sounds and released a lot of smoke as it popped out of the ceiling socket. The bulb burnt out and generated so much heat that it caused a hole at the base of the LED bulb.
