The PB70, the parabolic parallel beam light would usually be employed in drama productions.
For smaller teams any of the focusing dedolights with or without the parallel beam intensifiers can serve well.
In television studios we have employed a 220 W DLED30 light with parallel beam intensifier, lighting simultaneously four reflectors for the frontal and key lighting.
As back light and effect light we have used a 90 W DLED9 bicolor light, again with parallel beam attachment, lighting up five reflectors in a row.
Further LED lights were used for the background.
Since such lighting may be regarded as relatively structured light, it can be mixed with additional soft lights, the dedolight Ledraptor lights, to smooth the effect and give a more gentle and homogenous approach, still leaving the special character of the more structured dedolight Lightstream system.
Such a studio, let's say with a talkshow audience of five people was traditionally lit with about 30 kW. Our lighting would add up to a total of 790 Watt for similar light levels.
And therefore it again contributes to the ecology, as well as creating the minimum in heat generation, thus, adding extra savings that would otherwise be necessary for climatization.
In traditional studios, for example if you employed 100 kW, you may have needed 200 or 250 kW simply for the climatization system.
With this new approach and the drastically lower wattage the generated heat is also absolutely minimal, and may operate with minimal airflow, possibly none at all.
