Glossary
Color Rendering Index (CRI):
A rating system that describes
the effect of a light source on the color appearance of objects
(compared to a standard reference source of the same color
temperature). A rating of 100 is the highest possible CRI.
Typical cool white fluorescent lamps have a CRI of 62.
Lamps with rare-earth phosphors can have a CRI of 80 or higher.
Color Temperature:
The color a light source appears to be,
ranging from reddish (lower color temperatures) to bluish
(higher color temperatures). Measured in degrees Kelvin (ºK).
Diffused Light:
Produces a soft light with soft shadows
while illuminating a relatively large area. Illumination is
indistinct rather than obvious, distinct light beams.
Fill Light:
Supplementary illumination positioned to reduce
or eliminate shadows created by key light.
Flare:
Over-saturation of light that appears when too much
light is picked-up by a camera’s lens and reflected off its
internal glass elements.
Foot Candle (fc):
A measurement of illumination where one
unit is equal to the light of a candle at a distance of one foot.
Glare:
A condition caused by light within the visible field
that is brighter than the level of light to which the eyes are adapted.
Key Light:
The principal directional light. Usually
positioned off-center and angled towards the subject.
Three-point Lighting:
A basic lighting method in which key
light, fill light and back light are all used to illuminate the
subject while providing depth and texture.
FAQs
How long do bulbs last? Are they expensive?
Bulbs are
rated at 12,000-hour lamp life. Replacement bulbs can be
purchased from Navitar.
How much do the lights weigh? Will my ceiling support
them?
The Recessed Hi-Lite units weigh approximately 16.8
lbs (7.6 kg), The Original Hi-Lite units weigh approximately
8.3 lbs (3.8 kg). Most suspended ceiling grids are rated to
support more than 50 lbs. All units are shipped with a
supplemental support harness.
Which model is best suited for my application?
All models
will work in most situations. Which model best suits your
needs depends on requirements such as aesthetics, portability
or cost. For example:
Recessed Hi-Lite:
Best for areas where room aesthetics
are paramount, such as high-end boardrooms or
corporate headquarters.
Original Hi-Lite:
Best for applications where portability
will be needed, such as portable streaming studios or
use with “roll-about systems.”
What is the warranty period?
One year parts and labor,
excluding bulbs. (For a written copy of the complete
warranty, call Navitar at 1-800-828-6778 or 585-359-4000.)
