Stainless Steel 316 Underwater Fountain Light
The FD-UF010C18 is an 18W underwater luminaire designed for fountains, pools, and water features where corrosion resistance and long-term sealing are critical. The fixture uses stainless steel 316 for the housing, which resists pitting and crevice corrosion in chlorinated or saltwater environments. It operates on DC24V, making it suitable for low-voltage systems common in aquatic installations. The Osram LED chip delivers consistent output across a range of colour temperatures from 2800K to 6500K, or full RGB/RGBW colour control. The IP68 rating ensures complete protection against dust and continuous immersion in water, suitable for permanent submersion.

Compared With the Alternatives
Stainless steel 304 underwater light
316 has better resistance to chlorides and saltwater, reducing risk of pitting in harsh aquatic environments
Aluminium underwater light
Aluminium is lighter but prone to corrosion in chlorinated water; 316 steel lasts longer in aggressive water conditions
IP67-rated underwater fixture
IP67 is not rated for continuous immersion; IP68 is required for permanent submersion in fountains and pools
Use Guide
- Drill a 50mm hole in the fountain or pool wall at the desired location
- Install the fixture with the gasket in place and tighten the retaining nut evenly
- Connect to a DC24V power supply with proper cable sizing to avoid voltage drop
- For RGB/RGBW models, ensure the controller supports the required signal protocol
- Avoid direct contact with the lens during installation to prevent scratches
Stainless Steel 316 Underwater Fountain Light Questions
What is the cut-out size for this underwater light?
The fixture requires a 50mm hole for installation.
Is it rated for permanent submersion?
Yes. The IP68 rating confirms it is designed for continuous immersion in water.
Can it run on AC voltage instead of DC24V?
No. The model is specified for DC24V input only.
What colour temperatures are available?
Available in 2800K to 6500K CCT, or RGB/RGBW for colour-changing effects.
What is the warranty period?
This model carries a 3 year warranty. Across the FENGDIAN range, warranty is 2 to 5 years depending on the product.
Can we order a sample before a project order?
Yes. Sample orders are accepted, mixed samples are acceptable, and samples typically ship in 3-5 days.
How long does mass production take?
Mass production is typically 1-2 weeks, and goods normally ship by DHL, UPS, FedEx or TNT with 3-5 days in transit, or by air or sea freight.
