Fluorescent Flicker
Hello,
I’m shooting a scene in HD (F900, 24P) where I want
the effect of _sporadic_ flickering from practical and off-screen
fluorescent sources. We will have Kino Flo fixtures and ballasts,
but have a small Home Depot budget as well. I want an on-off
flicker which ideally could be controlled by a lamp op (similar
to a Lightning Strikes unit). Since the source is on camera,
it must be a true fluorescent globe. Please share thoughts
on the cheapest way to do this.
Regards,
Andrew Huebscher

Don't know if this will help, but. . .
I just bought a 2 or 3 way torcherie lamp for incandescent
bulbs. I used a fluorescent bulb in the socket, when the torcherie's
on off switch is set to low the bulb slickers quite well.
this effect is best when the bulb is cold, and hasn't heated
up yet.

What is a torcherie ? Is It dimmer, a flicker generator, or
?
Thank You

Sorry, Floor lamp for personal household lighting, not for
film production. A standard dimmer might give you the effect
you want, but I'm sure that the experts on flickering fluorescents
that reside here will chime in.
You might check the archives as well, I think this has been
touched on before. Best of luck, hope it was helpful this
time.

I have produced a random flicker with fluoro’s just
using a dimmer with a normal magnetic ballast fluoro, doesn't
work with electronic ballasts.
The effect the Director wanted in this old building was the
odd fluoro randomly trying to strike, as they do at the end
of their life.
We just put small electronic dimmers in the line and set the
volts so the starter would just fire but not enough volts
to strike the tube.

What in the UK would be simply referred to as a free-standing
uplighter.
Normally fitted with a 300W halogen lamp in the UK.
