Article Cool-Lites Explained
The models I have are the Interfit super cool-lite 9 and Interfit super cool-lite 5. In each case ours came as a set with a pair of matching lights with stands. The heads will fit onto a normal lighting stand, although each came with its own lighting stand. They have an inbuilt tilt bracket and a holder that allows an umbrella or umbrella diffuser to be used, each came with both a reflector kit and soft box kit, but the 5 and 9 bulb units go together in different ways. Most people will manage with one or two lights, and there are probably few occasions where most people would use 4. They are quite bulky items so you wouldn't want to put 4 up in a normal modern house. Each of the bulbs in my units are 28w, and in effect are compact florescent tubes. As a typical standard a 2ft florescent tube is 20 watts and I have 28 lamps in total, each at 28w = 784w, this is the equivalent of 78 1ft florescent tubes which would light a fairly large hall being used in a much smaller space. The manufacturers say each gives out the light equivalent of 140w in conventional bulbs, so in total 3,920w, or 39 100w light bulbs, power wise its using around a quarter of the electric that conventional bulbs would. They are said to last 8 times as long as ordinary bulbs and considering they are not on for long periods this should mean I don't have to change any bulbs for some years. Comparing the power of low energy bulbs to normal bulbs is always suspect, in part because many of us don't agree with the claimed amount of light they produce and between producers the clamed equivalent values vary, but there is a lot of light coming out of these multi bulb units, more than I actually need, allowing me to switch out a lot of lights, while still having a lot of control.
Putting them together and taking them apart is time consuming, at this time I still keep these units in the boxes that they came in so this means disassembling them, taking out all the bulbs and putting them back into their boxes etc. Switching from the reflectors to soft boxes is also time consuming and requires the bulbs, or at least a lot of them, to be removed as they splay out and you cant get the pieces you are changing over them. For most people this would not be so much of a problem as they would assemble the lights the way they would usually use them and leave them in this format, but undertaking both teaching and photographic consultancy, where I don't know what I am going to use them for next, and with limited space to store them as assembled units, I have chosen for now the time consuming but for me most practical option. It also offers me a rather unusual advantage in that I rent rather buy much of the equipment I use, and while its in the box and not in use I don't have to pay rental on it, but this is not a deal you are likely to get. Although many professional photographers do rent in equipment, including lighting kit, as and when they require it for individual jobs, often charging this on to the client. I have thought of putting one 9 and one 5 bulb together with a soft box on and the same with a reflector, or putting both the 9 bulb units together with soft boxes on and the two 5's with reflectors and then changing just individual units when the need arises, and only packing down units when I have to take them somewhere else. This last option is probably the one I will eventually settle on, as I would like to use them more than I do now, due simply to the fact that it is much quicker to grab a flash unit than undertake the assembly, and disassembly tasks.

Comparing Sizes Sizes
Assembling the softboxes In the illustration above you will see the soft boxes are made from material outside stretched over springy support rods, 4 for the 5 bulb and 8 for the 9 bulb, this gives it the shape. In the images you will see the lower ones have black ties on the ends, this is a strip that Velcro's back to a tighter position allowing all the rods to be put in place and then tightened. The softbox top fits over the ends of the 8 rods and material, and is slightly wedge shaped so once sprung in stays in place. The square softbox top for the 5 bulb unit has Velcro strips in the centre of each flat side. The reflectors also have a stretch cap that forms a soft box effect.

The images above were taken with two of the 9 bulb units, as shown in the image at the top of this page, the soft box on the left with 9 bulbs lit and the reflector with cover on the right, used to fill shadows, with 3 bulbs lit. I only used this arrangement as I had put the lights together in this order for this article. The HiLite being used as a background is not lit, and as you can see there is hardly any shadow, so the light boxes produce a very even soft light.
