Compared With the Alternatives
Stainless steel 304 underwater light
316 offers better corrosion resistance in chlorinated and saltwater, critical for long-term pool use
Plastic-bodied underwater light
316 body is more durable and resistant to impact and UV degradation, but heavier and more expensive
Mains-voltage underwater light
DC12V/24V reduces safety risk and allows use with low-voltage control systems, but requires external power supply
Use Guide
- Install the fixture in a dry environment before submerging to avoid water ingress during wiring
- Use a waterproof connector and seal all joints before submerging the light
- Ensure the power supply is rated for DC12V or DC24V and compatible with the fixture's input
- Avoid direct contact between the fixture and pool walls during installation to prevent stress on seals
- Clean the lens periodically during pool maintenance to maintain light output
Stainless steel 316 Underwater LED Swimming Light Questions
What is the input voltage for this underwater light?
The fixture operates on DC12V or DC24V, suitable for low-voltage pool lighting systems.
Is the light rated for permanent submersion?
Yes. It is rated IP68, which means it is designed for continuous submersion in water.
Can the colour temperature be changed after installation?
The colour temperature and RGB options are set during production. Custom colour settings can be specified in the order.
What is the warranty period?
