Inground lights (also called recessed ground lights or buried lights) are essential for modern outdoor lighting designs. These fixtures blend seamlessly into landscapes while providing functional and aesthetic illumination for pathways, architectural features, and public spaces. Below, we break down their types, technical specifications, and selection strategies for contractors and designers.
10 Types of Inground Lights & Their Uses
| Image | Type | Key Features | Best Applications |
|---|---|---|---|
 |
Adjustable Beam | 15°-60° directional adjustment | Highlighting walls, sculptures, trees |
 |
Ultra-Thin | 1.2” installation depth | Shallow concrete slabs, narrow spaces |
 |
Square Cover | Matches tile layouts | Modern plazas, geometric landscapes |
 |
Side-Emitting | Horizontal glare-free light | Driveways, ADA-compliant pathways |
 |
Frameless | Seamless 316 stainless steel finish | Luxury resorts, minimalist architectures |
 |
Frosted Glass | Soft diffused glow (60° beam) | Gardens, park trails |
 |
Asymmetrical Beam | 75% glare reduction | Building facades, signage illumination |
 |
Curved Linear | 30° bend radius design | Circular gardens, round structures |
 |
Long Linear | Up to 48” continuous lighting | Staircases, bridge edges |
 |
Standard Circular | Budget-friendly IP68 option | General landscape lighting |
5 Critical Factors When Selecting Inground Lights
1. Waterproof Performance (IP Rating)
- Minimum Standard: IP67 (submersion up to 1m for 30 minutes)
- Harsh Environments: Opt for IP68 or IP69K with pressure-equalization vents
- Material Pairing:
- Housing: Marine-grade stainless steel (Type 316)
- Seals: Dual-layer silicone + EPDM
- Glass: 12mm tempered with anti-fog coating
2. Beam Angle & Light Distribution
| Purpose | Recommended Beam | Fixture Example |
|---|---|---|
| Accent lighting | 15°-25° narrow | Adjustable beam type |
| Pathway illumination | 60°-90° medium | Frosted glass type |
| Area flooding | 120° wide | Square cover type |
3. Load-Bearing Capacity
- Pedestrian Areas: 1000+ lbs/sq.in (e.g., parks, walkways)
- Vehicular Zones: 2500+ lbs/sq.in (reinforced models required)
4. Installation Depth
- Ultra-thin models: 1.2”-2” depth
- Standard models: 3”-6” depth
- Always add 20% extra depth for gravel drainage base
5. Anti-Glare Features
- Frosted glass covers
- Asymmetrical optics
- Recessed LED modules
Step-by-Step Installation Best Practices
Pre-Installation Prep
- Drainage Layer: 4” gravel base under fixtures
- Slope Grading: 2% slope away from lights
- Cable Management:
- Use IP68 gel-filled connectors
- Create drip loops below junction boxes
Installation Process
- Excavate to required depth + gravel buffer
- Secure fixture with UV-resistant epoxy
- Connect wiring using waterproof connectors
- Test for leaks (submerge for 24 hours)
Maintenance Checklist
- Monthly: Clean glass with non-abrasive solution
- Annually: Check seal compression (≥0.6mm)
- Biannually: Inspect drainage channels
