Quartz Halogen vs Incandescent
Both operate on same principle - current through tungsten
QH encase filament in quartz casing filled with halogen gas. Run hotter, brighter, whiter. More
consistent colour/colour temp. Made for photography. Ones he has here today are of this
kind.
Red heads - get 1 1000 Watt light, 2 600 Watt. These are the smallest they have in actual
film trucks and stuff. Great lamp for what we need. Also have smaller kit.
Light kits for loan:
Lowel ViP Pro-light:
The little guys
Middle of the row, not industry standard, but good for video
250 W
4 barn doors to control light. Can get hot if plugged in for a while, use gloves.
Flood or spot is a control on the side, on off button in back.
If bulb blows, bring it in if near campus. If not, get bulb when booking lights,
replace yourself. DO NOT TOUCH BULB WITH BARE HANDS. Pull out by ceramic,
test before putting back together.
Red Head (Ianiro Varibeam):
Also has flood and spot setting, on back
4 barn doors
Can pan or tilt on stand
Harder to change bulb, have to take off doors first
Have the screen on
Ease one end out, pull it out
50 bucks each be careful!
Bulb moves in and out in relation to reflector, that's how it goes between flood
and spot
Little ones have glass lenses, but these are open face bulbs
Kit stands - light weight, easy to cart around, big enough for these lights
Also have bigger ones, used more for fluorescent lights
Look pretty similar to music stands in how they unfold/work
Put on, spigot through whole, tighten with screw
Always start with top risers - awkward to start at the bottom - will have to get up higher to
adjust - will look like a rookie!
Head cable - plugs in to cable coming out of light, don't yet plug into wall, plug into one of
the red cables first (AC cables - 14 gauge is smallest you want to go)
Don't plug directly into wall - need a longer cable so you're able to move it easily and not
have a taunt wire - recipe for disaster
Always tell someone when you're plugging a light in. Never move a light while turned on.
Panning and tilting is fine, as is moving up and down, but never pick it up and move it. When
