LED underwater lighting is emerging in the market. The advantage of led is that this light source (under the condition of correct application) has a much longer lifespan than halogen. By comparison, a halogen underwater light has up to 1,500 burning hours, while a LED underwater lamp can reach 50,000 burning hours.
The switch from halogen to LED has a significant effect on the energy consumption of underwater luminaires. There are now LED underwater lights on the market with a power consumption of 45W with significantly higher light output than a 300W halogen underwater light.
As the lifetime of LEDs in theory is 20 to 50 times longer than halogen, some manufacturers have responded to this with a new design in which the light source is sealed-off water and airtight with special resin. This new generation of LED underwater lights have fewer problems with waterproofing.
