The History of SPERTI
from Dr. George Speri Sperti to the present day.

Dr. George Sperti has an entry in Wikipedia, below is an excerpt:

"Sperti graduated from the University of Cincinnati in 1923. Shortly afterwards he was named Director of the Research Laboratory. His invention of an Ultraviolet "Vitamin D" lamp to irradiate milk to add Vitamin D without changing the flavor was sold to General Foods for US $300,000. Sperti donated the entire amount to the University to continue basic research, and went on to develop a successful business line of ultraviolet sunlamps."

SPERTI SUNLAMP was founded by Dr. George Sperti. Dr. Sperti was the recipient of numerous degrees and awards for his work in the advancement of ultraviolet science. As a result of this work, he founded SPERTI SUNLAMP to manufacture ultraviolet bulbs and appliances for the general public.

1923...Sperti graduated with a degree in electrical engineering from the University of Cincinnati. Immediately his talents and intellect were well respected and he began conducting scientific research and trying to create inventions while still a student.

1933...SPERTI SUNLAMPS were first manufactured at 424 E. Fourth Street, Cincinnati, Ohio. These lamps were screw-in bulbs consisting of a tungsten filament and small mercury arc. They were approximately 100 watts and were primarily used as reading lamps. They did not produce a tan, but were intended to provide the user with full spectrum, healthful radiation for everyday chores.

1937...Full spectrum bulbs were discontinued and replaced with lamps intended to produce a tan. This product was called a medium pressure arc lamp. During this era, the sunlamp company was called Science Laboratories, Inc. At this point, Dr. Sperti's research pioneered developmental data supporting Vitamin D production in human skin when exposed to ultraviolet radiation.

1939...The name of the company was changed to Sperti Products.

1940...The lamp making business outgrew the facilities on Fourth Street and relocated to larger quarters. The sunlamp was changed to what is called a high-pressure mercury arc lamp. This type of product became Dr. Sperti's primary product.

1942...The name of the company was changed to SPERTI, INC. During the war years, SPERTI, INC. manufactured various instruments for the U.S. Navy and U.S. Air Force (bomb sites, mercury switches, distance sites and gauges). The only tanning lamps manufactured during the war were for military purposes.

1949...SPERTI, INC purchased Faraday, Inc. (Adrian, MI), a small manufacturing company. The ultraviolet tubes were made in Cincinnati and shipped to Adrian, MI for final appliance assembly. The name of the company became SPERTI-FARADAY.

1950...SPERTI-FARADAY purchased Cooper Hewitt Electric Co., Hoboken, NJ.

1954...Sunlamp tube production was moved from Cincinnati to Cooper Hewitt in Hoboken, NJ. The appliance was made in Adrian, MI until 1958, when all production was centralized in Hoboken. The Adrian, MI business location was sold.

1963...All production was moved to Northern Kentucky, where SPERTI products continue to be manufactured.

1991...SPERTI SUNLAMP was purchased by KBD, INC., a Kentucky held corporation. KBD is a successful manufacturing company with abundant capital resources and management experience. KBD owners, Kathy and Jim Shepherd, continue to improve SPERTI ultraviolet products for marketing in the health and beauty markets.

2004… KBD, Inc. purchased a larger manufacturing facility allowing additional space required for continued growth of product lines.

2006...KBD, Inc., manufacturers of SPERTI products, reintroduced to the marketplace the D/UV appliance designed for the production of Vitamin D in the human body. KBD expanded the product line to include appliances for the treatment of Seasonal Affective Disorder (S.A.D.).

2010….KBD/SPERTI introduced fluorescent technology to our family of Vitamin D products, and added multi-voltage capabilities (220V-110V) to our UV lamps allowing world-wide marketing and sales.

2011….KBD/SPERTI introduced the FIJI TABLE TOP FLUORESCENT SUNLAMP. This unit provides increased area of coverage, cooler operating temperatures and immediate restart capability. With the multi-voltage capabilities (220V-110V) the FIJI SUN is attractive to individuals around the world.

2012….KBD/SPERTI continued the progression of fluorescent technology into its Phototherapy products. The PH-36F (Psoriasis unit) not only contains fluorescent technology, it includes longer bulb life, cooler operation, lighter weight and multi-voltage usage. The spectral output has NOT been altered and continues to offer affordable home treatment for Psoriasis.

2013 - 2017: Vitamin D deficiency and the many benefits of healthy Vitamin D levels continue to be a popular and trending health subject in the USA and worldwide during these years. This Vitamin D enlightenment along with some good press about our Vitamin D Lamp has made it a very popular UVB device. Our Vitamin D Lamp has also received the endorsement of several prestigious Doctors including internationally renowned Vitamin D expert: Dr. Michael Holick.

2017 and onward: ... KBD/SPERTI will continue to grow and introduce our quality sunlamp products within the USA market and internationally, and we also continue our marketing expansion into the health care industry.
