PAR is an acronym for Parabolic Aluminized Reflector. PAR bulbs utilize a parabolic mirror to concentrate their light output into a focused beam for wide flood, regular flood, and spotlight angles, making them a much more precise option for directional lighting than, say, a BR (Bulged Reflector) bulb. Much like a BR bulb, however, a PAR bulb's diameter is determined by the numerical value following its acronym. The size can be found by measuring the diameter from the widest point of the bulb in 1/8 of an inch increment. For example, a PAR16 (the smallest of the PAR series bulbs, by the way) would have a diameter of 16/8" - or 2 inches.
PAR LED bulbs, like those made by GoodBulb, can be found in a variety of applications in both residential and commercial settings.

Light Bulb Moment
To expand on the statement above, in Japan, researchers have been able to prove the existence of bioluminescence in humans through a series of images taken using a cryogenic charge-coupled device, a highly sensitive imaging system. Through this, they discovered that the human body emits light both directly and rhythmically. The intensity of the light emitted is about 1000 times lower than what is detectable by the naked eye and is constantly changing based on the time of day. For example, we shine brightest in the middle of the day and dim toward the evening. Except for baby brother, he’s not very bright at any point during the day. This is tracked through ultraweak photon emissions released in the form of light through changes in energy metabolism within the body.
Researchers also found something quite intriguing with this discovery in that our bioluminescence does not correspond to the amount of heat we naturally generate. Thermal imaging taken shows a wholly different visual result to that of the highly sensitive cameras used to capture our bioluminescence on film. This goes to show how much more interesting life can get if we are willing to keep digging!
STOP BUYING BAD BULBS
Buy A Light, Be A Light.
16% of the world's population still lives without electricity. GoodBulb believes we all have the opportunity to create a positive impact. Join us in choosing to buy quality products that help you create that positive impact in the world. Those who live without electricity often rely on kerosene lanterns. These are inefficient, expensive, and dangerous. In fact, Kerosene is the #1 cause for devastating fires in remote villages, destroying homes and endangering lives. With every light bulb you purchase, GoodBulb provides solar lanterns to families who live without electricity.
LED bulbs not only bring down your energy bills but are also more environmentally friendly when compared to incandescent bulbs and compact fluorescent lights (CFLs). LED bulbs contribute the least amount of carbon dioxide into the atmosphere of all lighting sources. LED bulbs consume less power per unit of light emitted. This reduces greenhouse emissions from power plants. Carbon dioxide emissions for LEDs are also low. One LED bulb will minimize greenhouse gas emissions by almost half a ton. For example, an incandescent bulb results in 4,500 pounds of CO2 annually, while LED bulbs contribute just 451 pounds of CO2 per year. LED lighting can last up to 20 years, this longer life decreases the production of more bulbs, reducing the greenhouse emissions created by the manufacturing process.
LEDs have the best light distribution by focusing light in one direction as opposed to other types of lighting that waste energy by emitting light in all directions. Fewer LED bulbs are needed to achieve the same level of brightness given off by other forms of bulbs. Less bulbs reduce energy consumption and benefit the environment.
LEDs generate less heat during use so cooling costs are much lower. Incandescent bulbs release 90% of the energy as heat. While LED bulbs release 5% of the energy as heat and the rest is made into light. LEDs also contain ZERO mercury, unlike CFLs.
