Hydro-Flux Flowbright


Hydro-Flux have almost 80 years of experience in the swimming pool industry, designing and constructing swimming pools over the wider Yorkshire area. After installing and repairing countless swimming pool lights and having to deal with all the frustrations associated with the standard light design, they had an idea which they hope will revolutionise pool lighting. The resultant product – FlowBright – a water powered LED swimming pool light, utilising their patented, high-flow, low resistance turbine technology to generate its own electrical requirements. FlowBright eliminates the need for any additional equipment, complex installation and repairs, and ongoing electrical costs.

The concept behind FlowBright is very straight forward:  When FlowBright is installed in your pool, water returning from the filtration system passes through the assembly. The patented turbine technology then extracts and converts a percentage of the kinetic energy in the returning water into electrical energy. This energy is then utilised by the latest in high performance LED technology to illuminate the swimming pool. The water then flows through the directional exhaust at the bottom of the system. Attaching FlowBright to the return inlet is very straight forward as all inlet use a standard ½” threading; simply screw it in and that’s all.


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. FlowBright also protects the environment. Because it generates its own electricity it doesn’t rely on the mains electrical grid for its power; FlowBright produces zero carbon emissions during its operational lifetime. That is why FlowBright is the most environmentally friendly swimming pool light available on the market today.

Optima took the company’s initial concept sketches and worked with their Chief Design Engineer, Douglas Burnham, to take those original rudimentary ideas into a robust and manufacturable unit. Our expertise in Industrial Design and 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.


FlowBright 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. Hydro-Flux will be working with Optima Design in the future while they continue to develop their product range.
