Thank you very much!
You do indeed need a lot of power and space to achieve the same amount of light a strobe puts out with continuous lighting but you just cannot replicate the look of a single arc light source as well as the flow of shooting with continuous lighting.
In that picture you have quite a collection of different light sources; they are all really quite small so I can definitely imagine you not having enough light with ISO 400 film. They might also have had different white balances which would not have worked in your favour if you were aiming to have a consistent light balance.
Since I tend to modify them with frame silks or daylight softboxes quite often I do not really care all that much whether they are PAR or fresnel. For durability I have come to using Arri M18 and M40, but Jokerbug and Mole-Richardson are also established names.
I really like using daylight balanced primaries and bringing in tungsten fresnels accents to warm up the frame… but then you can also probably just do that with gels. So many ways to slice a cake I guess.
Keep in mind that I used to work as a lighting technician on sets where 3 or 4 5000 W lamps were used rather often so my idea of what makes sense on set is very different from someone setting everything up on their own and don’t have 1/2 day or a full day of studio time to pre-light a set!!
PS. I have started to work on ways to achieve those effects in less time and with less man hours, hopefully will be able to show something for it soon with my own work!
