Light pollution:

As a culture, it is difficult to retrain ourselves; discarding what is comfortable and adopting new ideals.
As humans, light has an incredible effect on our mood, productivity and sense of security.
As individuals, we have become aware of our impact, we need to consider unnecessary lighting.

We often over light our homes, businesses and streets, creating preventable light pollution.
We have found that native animals have been disturbed or displaced due excessive lighting.
How many times have you missed out on cosmic events due to much light in our night skies?

Recognizing and reducing light use or changing your lighting habits, is a difficult, yet rewarding move.
Informing yourself and others to moderate the overuse of light is vital in combating light pollution.

The Dark Sky Association plays a critical role in assisting manufacturers develop lighting solutions.

LEDs enable precise control over intensity and color, allowing us to customize our environments.
In turn, we can optimize usage,
While green refers to environmentally friendly, true green refers to conservation.

Design principles:

Solid state lighting requires us think the way that we use and design with light.
Filament based or conventional lighting, consists of an omindirectional light, receptacle and shade.
These components are used to conceal and redirect the effects created by an omnidirectional source.

Due to the efficient operation traits and tiny form factor of LEDs, we have increased design flexibility.
By using LEDs we can direct the light where needed.
In some instances, by using LEDs, we can reduce or eliminate the need for a fixture all together.
While this is incredibly unpopular to luminaries designers, this opens up the world of creative lighting.

Watts to lumens:

A watt is measurement of intensity and consumption often associated with conventional lighting.
We have grown accustomed to what type of light
we know light, where and how it’s used.
LEDs are rated in MCD or millicandela but high powered LEDs are commonly measured in lumens.
LEDs are directional sources, emitting light in beam angles.
Filament based lighting projects light in an omnidirectional, 360 degree pattern.
We are familiar with the wattage consumed and produced by filament based lighting.
LEDs wattage is fractional and not applicable to consumption, making lumens difficult to translate into watts.

LED Standards:

Not all LEDs are the same; quite literally, you have thousands of options.
Inexpensive, poorly manufactured LEDs, will vary in intensity
and color, while high quality LEDs will have little to unnoticeable variance.

Most consumers do not have access or means to validate specifications provided by LED manufacturers.

Most manufacturers are not interested in explaining or guiding you in how to properly use their product.
Typical LED manufacturers know this and they are more concerned in creating the brightest LED.
This is due to lack of standardization within the industry.

Claiming long product lifetimes, high intensities and color rendering, these devices are rated using simulated testing.
Be cautious of manufacturer offerings and claims when making an investment in solid state lighting.

LED manufacturers often disregard the way designers use their products.
Methods of standardization need to be adopted to provide usable methods of translating intensity, color and coverage across LED types/variations.
