The '''Gradient Bright''' is a [[Czech Republic|Czech]] single-place, [[paraglider]] designed and produced by [[Gradient sro]] of [[Prague]]. Originally produced in the mid-2000s, it was still in production in 2016 as the Bright 5.<ref name="WDLA04">Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 19.

==Design and development==
The Bright was designed as a beginner and [[flight training]] glider. The manufacturer says that the "Bright5 is the best school glider Gradient has ever built." The models are each named for their approximate wing area in square metres.<ref name="WDLA04"/><ref>{{cite web|url=http://www.gradient.cx/en/Bright5|title=Gradient Bright5|work=[[Gradient sro]]|accessdate=2 June 2016}}</ref>
==Operational history==
Reviewer Noel Bertrand singled out the Bright in a 2003 review as deserving of "praise for its excellent performance at low speeds".<ref name="WDLA04"/>
