Hydro-Flux Flowbright


Hydro-Flux have over 20 years of experience in the installation and maintenance of swimming pools and the supply of pool related accessories.  They had an idea of creating a new way of lighting pools, which is currently a costly and complex process that requires power to be supplied to the light units. The resultant product is the revolutionary ‘Flowbright’ which uses low-power, ultra-bright LEDs, that are powered using the pool filtration system. The light simply screws into the return inlet and the water pressure powers the light by means of a high-flow turbine.  The simple installation means no additional electricity costs, elimination of external transformers and no requirement for the laying of ground cables, which can be costly and disruptive.

The patented electrical generation system is fully encapsulated in resin, meaning there is no danger of it coming into contact with the water. The self powering device also means there is no risk of electrocution as the light is not connected to mains electrical supply. It’s low power requirement also makes it an ecologically sound product, reducing system complexity and eliminating the need for mains supply.

Optima took the companies initial concept sketches and worked with their Chief Designer to engineer a robust and manufacturable unit. Our expertise in injection moulding ensured minimal changes were required when working with their UK based moulders. The design went through several iterations of testing with a fully prototyped assembly in order to test form, fit and most importantly function. Critical to the success of the product was the shape and configuration of the waterways to ensure that optimal power was generated by the unit under variable flow conditions.


The light is manufactured and assembled in the UK and has recently been launched with huge interest in the UK and overseas. Complementary products and features are already planned, these include a smart control app and colour configurable LED’s.
