HMI style lights

This is a film light which has about the same light output as a red-head but at only 150W power consumption. It uses a bulb which is used in HMI lights. The parts are:
- Lanzini, Alaska display light. They are the lightest and available from many places but any other for 150W MH bulbs will do.
- par 56 barn doors. They fit exactly around the light
- aluminium U shaped bar & self tapping screws (see picture below):
- Calumet rapid adapter which allows mounting the lamp on a standard tripod

Important is that the bulb has a colour rendering index (CRI) of more than 90%. The Osram Powerstar bulbs are generally best and are indistinguishable from daylight on camera. They have a colour temperature of 5200K which is the same as daylight. They work nicely as a fill against the ceiling in a INT/DAY scenario and also as a source of sunlight. If used in interior shots it is recommended to balance the camera also to daylight and wrap half C.T. blue around practical lights which are usually too bright anyway.


  1. addendum: Sarmed just recommended this light which is much cheaper than the Lanzini one:

  2. Fantastic information. I have already ordered two lights. Thanks Bernd!

  3. Here is another link:

  4. The light from Lyon company has arrived. It is very heavy about 4 KG. Bernd, do you know what is the weight of the light head which you have

    I may have to get them returned or get a very good stand for them. But the real problem will be that they will tilt because of the weight and the tightening screws will not be strong enough to keep them in place.

    OK another thing:
    This info on the link to the bulb mentioned above


    says on the page:
    Excellent colour rendering 91%.

    But the below it in the column it mentions CRI 80.

    Is it OK to get this one to get the 90% above CRI
    Thanks :)?
