I would like to know if someone
who has a workprinter can give me the reference of his bulb lamp.

I don't have a workprinter but I believe they said that it used an
ordinary 40
watt high intensity desk lamp bulb. The kind that has a smaller version of
a
standard light bulb screw base. They are available at any hardware shop.

I try this kind of bulb light but it's too hot. I can't touch it after few
seconds.

It is a possibility they are not operating the lamp at it's full rated
voltage.


Also, The GAF\Ansco projectors that they were using for the workprinters
had a
design where the lamp reflected off a special mirror, (cold mirror) and
the
heat will not be reflected to the film.

1. Move the light a long way from the projector

2. Use a fibre optic guide

3. Use a small low-energy bulb. (Minature fluorescent)

4. Use a white LED(s)

Me, I'd go the last route with a suitable diffuser. When I tried this
some years ago we used the lighting from a Durst colour enlarger - that
also allowed colour correction of the light. But as I say, now I'd use a
LED.

Hi!

The bulb used in the Video WorkPrinter is, indeed, a standard 40 watt
"vanity" bulb found at local hardware stores (in the states) at about
2 for a dollar and last over 1500 hours. The bulbs are hot to the
touch but are not focused, so the heat is not concentrated on the film
frame. Also, the light is bounced off a diffusion panel, which also
keeps the heat from the film. And, lastly, the bulb sits 90 degrees to
the film plane and the chassis wall acts as a heat sink, keeping the
film totally cool. The color temperature of the bulb is well within
any modern video camera's ability to white balance for correct color
and you can leave film in the gate of a WorkPrinter or CineMate unit
for a week with the lamp on and it will never blister or even lose
focus.
