Interfit cool lite for yoga class shoot

Has anybody experience of using these Interfit Cool Lites for shooting video?

They use low energy fluorescent lamps providing daylight (5200k).

The heads have 5 or 9 independent lights, and can provide equivalent of 500 watts or 1000 watts.

They can be used in a softbox.

I am looking to buy some lighting for a yoga room (25 foot by 20 foot) which will be used to increase the existing light in the room, in order to shoot a yoga class with about 6 or 7 people in the class.

The yoga room can be seen in an exisiting video on the home page of the Burren Yoga and Meditation Centre website.

There are large ceiling to floor windows on two sides of the room, and 9 100 watt ceiling (dimmable) incandescent spotlights in the ceiling, and 12 wall lights (approx 9 foot high from ground) 100 watt dimmable.

I am thinking of using two softboxes to provide more lighting.

The kit i am looking at is called Interfit INT217 Super cool-lite 9 Twin head Kit.

Has anyone any experience using these particular lights?

Thanks in advance,
Dave
 
It sounds like you are considering buying your first lighting fixtures. The issue with the spiral fluorescent bulbs is low CRI. It's more important to get get realistic skin tone and accurately rendered colors, than it is to "conserve energy" or reduce heat emissions. Depending on the time of day, you may be overwhelmed by the light from the windows. Do they have blinds, curtains, tint film? The spiral flo's aren't going to match the color temp of the practicals in the room either. Have you shot any test footage at the time of day you expect to be filming. How wide do you expect the master shots to be? I'd rent a couple of Kino 4' 2 banks with Tungsten tubes and diffusion to even out the lighting in the room.
 
Hi JD,
Yes.... these would be my first lighting fixtures.

I am based in Ireland which is quite far North, so in the winter the lighting is completely different to summer, morning very different to mid-day and to afternoon.

I can't predict time of day or year that i will want to do a shoot, as it can be anytime.

I am trying to buy rather than hire lights, as i can never be sure when we have a yoga workshop that can be staged for filming, so i am hoping to have as many options with the lighting, mainly so that i can balance the glare from the windows.... or lack of light if dark outside.

I do have curtains, but no blinds and no tint film. The latter would be a great investment longer term, especially the one that can be variable.... depending on the angle of the polarizing filters used with it.

I am not too concerned with realistic skin tones, as these videos need not have 100% quality lighting etc...... at present i am trying to minimise the risk of having black/dark bodies surrounded by glaring windows, or darkly lit people which don't hold one's attention, or don't have enough detail.

The Kino 4 foot sound like they throw out a lot of light..... but they also look expensive. I can't even see purchase prices for them in the UK or Ireland.... only rental prices.

I don't even know what a master shot is? But if i guess that this would be a wide angled shot to view the viewer the context of the scene...... it could take up most of the room..... so depth of shot approx 20 foot, width approx 15 foot.

I guess i am look for lights that can be used to throw additional lighting onto the people in the shot, to make them brighter in relation of windows in the background (if the light outside is strong enough to need counteraction on that day and happens to be coming from behind the people).

I do try to keep the windows out of shot most of the time.... but as the action can be moving, this is difficult at times. Also the views out of the window can look great, and can add a nice atmosphere or nice background shots to the action inside the room.

The best views of the yoga room tend to be shooting with my back to the wall..... facing about 6 people practicing yoga who are facing the camera..... BUT with two windows behind them (facing the camera) and 3 windows to the side of them (which can throw great light onto room and people).

I thought if i position one interfit light box (equivalent to 1000 watts) to either side of me facing the people, this would throw more light onto the front of the people facing the camera. And i believe the individual 9 lights within each interfit head can be switched on or off (thus giving more or less light when required).

I am open to any advice, and would also appreciate hearing from anyone who is or has used these Interfits.
