Greenstar Products is a US company founded in 2009.
Since December 2012 owned by Toshiba Lighting & Technology Corporation.
In the beginning of 2016 the former founders and owners purchased the factory
and have now 100% control of production and development again.

Greenstar is based in San Antonio, Texas and also have a subsidiary in India for research & development.

The basic philosophy is to develop LED Lamps focusing on the best possible heat transfer
from the components of the potentially damaging heat. This is important in order to
increase the service life of the components and thereby the lamp.
At the same time Greenstar will not compromise on the choice of components.
