Light Output vs. Life
The life of an incandescent lamp and its lumen output
are both determined by the filament design. These
characteristics represent a give-and-take relationship—
one must be sacrificed to improve the other. There
are many choices available to the consumer, each
one marketed for a particular application, purpose or
feature.
It is important to determine your customer’s priorities and
needs when recommending a light source purchase. Is
the lamp going to be placed in a hard-to-reach area,
making long life more important than light output? Or
will it be a workhorse, illuminating important tasks and
needing maximum lumens?
The Federal Trade Commission instituted new packaging
labeling requirements in 1992 to explain the function of
a lamp better to the purchaser. So if you know your way
around this labeling, you can suggest optimum choices
for your customer, or explain the features to customers to
allow them to make their own educated decisions.
Rated Life
There is a common misconception that the “Rated
Life” of an incandescent lamp is a measure of how
long the lamp should burn, this is not true. The rated
life of a lamp is the point where 50% of the bulbs have
burned out, and 50% are still burning, under laboratory
conditions. For example, the S2808, (65BR30/FL) is
rated at 2000 hours, this means, some will burn out at
1000 hours, some will last 3000 hours, but ½ will still be
burning at 2000 hours.

Krypton decorative bulbs create a brilliant sparkle,
similar to the look of halogen. Additionally, Krypton
bulbs last longer than conventional incandescent
bulbs, maintaining their lumen output for the full
course of their life.

While these very long life lamps were originally
designed for traffic signals, we offer them primarily
as an extraordinarily long life product. Per Title
20 Section 1605.3(m) of the California code of
regulations, these lamps may not be sold or offered
for sale in the state of California for use in traffic
signals.

These Natural Spectrum light bulbs contain
Neodymium, a rare earth element that filters out the
excessive yellow part of the spectrum to which our
eyes are most sensitive. Made of hand blown glass,
these incredible bulbs are the closest replication of
natural sunlight available in an incandescent. These
bulbs last up to five times longer than ordinary bulbs,
show colors more accurately, increase the contrast
between black and white, and reduce glare,
eyestrain, and fatigue. While other manufacturers
use a film that can degrade from the heat of the
incandescent filament, the Neodymium in these
lamps are integral to the glass, and therefore will last
for the life of the bulb.

ShatterProof lamps are designed for any
application where the bulbs are at risk of being
broken. The rubber coating will contain the glass
particles should the lamp break, keeping it from
falling into food, or anywhere else. Many jurisdictions
now require the use of coated lamps in all food
preparation, and service areas.
