Use of halogen shop lights for studio photography

Does anyone have any experience using halogen shop lights for studio

photography? For about $40 you can get a 1000 watt light, together

with a stand that reaches up to about 6 feet. The amount of light

that a couple of these units puts out is enormous. They are intended

for shop work and I have used them for a couple of years to light both

indoor carpentry projects and automotive repairs at night. This leads

to my questions. What is the color temperature of such lights?

Should I use and 80A or other filter if I use them as studio lights?

Is there some reason you would not want to use them for indoor studio

work?

We have used a few of the "shop" lights for video work.

They have worked well in our television studio and

occasionally being taken into the field for production. The

more expensive lighting units sold for video productions

are smaller and easier for the students to carry. "Shop"

lights will never replace our studio fixtures; but,they are

low cost addition that fill some needs. Studio fixtures

have more controlled beams, more uniform, lighting,

variable coverage (spot/flood), and barn doors.

Color temperature of the lamps is usually 3000K or

3200K. You would have to look up the ratings for the

specific lamp that you fixture uses.

The ones we use have Non Uniform light output.

Aiming a fixture at a wall results in noticeable uneven

horizontal bands of lighter and darker areas. Our

students are told to bounce the light off of ceiling, instead

of lighting the person direct, when shooting interviews

away from the studio. In the studio we use diffusers in

front of these fixtures.
