Signify's new Philips Seacage 340W fish light helps to optimize growth results and reduce sea lice treatment up to 50%

June 10, 2020


Eindhoven, the Netherlands – Signify (Euronext: LIGHT) the world leader in lighting, today announced its latest innovation in aquaculture LED lighting. The company launched the new Philips Seacage 340W fish light which helps to optimize growth results for land- and marine-based cultivation of salmon and also shows proven results for other fast-growing fish species like seabass and seabream. The unique light distribution helps to prevent exposure to sea lice, reducing treatment up to 50%.


Light is a powerful tool for enhancing fish production and welfare. With an optimized contrast ratio, Philips aquaculture LED lighting supports a lower food conversion ratio and the right light distribution helps to prevent sea lice exposure. With smooth ramp up and low dim levels it also reduces stress levels for the fish, improving their welfare. The light spectrum is optimized for the distribution under water, the eye sensitivity of the fish and the pineal gland photoreceptors, maximizing the contribution towards growth at their best without maturing. Salmon are kept in a perpetual state of summer to prevent spawning and maintaining great taste and texture in the on-growing stage.
Unique in its kind is the light distribution, singly directed downwards in the seacages or tanks. The optimized light density in combination with the downward light beam ensures that the fish will swim deeper. And when installed below 5 meters, it reduces the need for sealice treatments as the fish will mostly swim below the sealice belt. This also lower the amount of electricity that is used and ensures that there’s no light pollution created. In tanks, the light distribution addresses the need for lighting in every part of the tank ensuring light can reach where it needs to reach, without the fish or tiny particles obscuring the light.

Growing salmon with a high market value at low operational costs while maintaining constant production levels, is challenging. In Norwegian farmed salmon, delousing accounts for up to 10% of production cost. And, with fish feed making up 50% of operational costs, any reduction in food conversion ratio will result in more profit.


The Philips Seacage 340W fish light is robust and easy to handle. On top of improving growth rates and significantly reducing sea lice exposure, our new energy efficient light lowers the food conversion ratio resulting in lower production cost. We help our customers to maintain constant production and at the same time improve the welfare and sustainability of the fish."
