There's more to LED conversions than just cost savings

LIGHT INTENSITY

Here is what a room looks like with lighting delivered at
different degrees of Kelvin:

WESTINGHOUSE LIGHTING

Lumens is the measurement of light intensity. The highlyfocused beams of an LED mean that it is far more efficient at
producing light, as all the light output is sent in one direction, versus the omni-directional light emitted by traditional
sources. Thus, an LED light bulb of just a few watts can match
the output of a 25, 40 or 60-watt traditional incandescent bulb.
Ultimately, this lower consumption of electricity (i.e., wattage)
is what provides the ongoing energy cost savings.
Typically, your lighting consultant or contractor will match
the existing amount of light from your incandescent or fluorescent lighting. Accordingly, I will spare you the details of
how lumens are measured.
So just how much are the savings? Look at this simple
comparison of just one bulb both generating an equal amount
of light intensity:

My personal experience is that selection in the 3,000K range
for interior lighting will be the most pleasing. At less than
3,000K, lighting tends to look very soft and whites tend to look
muddy. Parking lots typically utilize 7,000K for their intensity.
If you recall the office fluorescent light tubes of the past, these
two color temperatures correspond with what was commonly
referred to as daylight and cool light.

COLOR TEMPERATURE

WESTINGHOUSE LIGHTING

Color temperature is described as a method of describing the
hue characteristics of light, usually either warm (yellowish)
or cool (bluish), and measured in degrees of Kelvin (°K) as a
low burning fire would give way to oranges, yellows and all
the way up to white hot.
First, a basic reference chart to show you how the Kelvin
scale works. Whereas the Kelvin scale is measured from 1,000
to 10,000 (see below), LEDs are available in the center of this
range, from 2,700 to 7,000.

Despite these differences in color temperature, not all artificial light sources are equal in their accuracy either. The Color
Rendering Index (CRI) measures the ability of a light source
to accurately render all frequencies of its color spectrum,
when compared to a perfect reference light of a similar type,
i.e. color temperature.
This is rated on a scale from 1-100. The lower the CRI rating,
the less accurately colors will be reproduced. For reference,
an incandescent bulb is a perfect 100.
Not to confuse you with details, the CRI comprises 14 unique
scales: the first eight (R1-R8) are for medium saturated colors
and the last six (R9-R14) pertain to highly saturated colors
(red, yellow, green and blue) as well as complexion and leaf
green. Below is an image that shows how CRI results affect
the way we see objects, specifically food, where appealing to
one's appetite is particularly important.

When planning your LED conversion, as demonstrated
above, there is more to consider than just long-term savings.
First, select the color temperature, and then carefully analyze
the CRI data on your product selection. Ask your supplier for
the complete details of every type of light being selected.

OTHER FACTORS
Many local municipalities and several states offer incentives
for conversion that may cover a significant portion of your
initial costs. The application of this grant money should be
