Buying Guide
- What should you consider before buying?
Choose lights with IP68 rating for full submersion, depth compatibility, and durable seals. Look for 12-24V compatibility for safe underwater use and energy efficiency. - How many lights do you need?
For small ponds, 2-4 fixtures often suffice; larger landscapes benefit from 4-pack or multi-head setups to ensure even illumination. - Should you favor warm or neutral white?
Warm 2700K-3000K creates a cozy look for gardens and ponds; cooler options are suitable for modern architectural accents. - What about installation?
Check cord length (commonly 16.4 ft) and whether glue sealing or gasketed housings are required. Plan for transformer, wiring layout, and potential weights to prevent floating. - Durability and maintenance:
Brass fixtures and glued seals tend to endure outdoor environments better. Consider long-rated LEDs (up to 50,000 hours) to minimize maintenance.
