Buying Guide: 12 Volt Recessed Lighting Buyer’s Checklist
- Voltage compatibility: Confirm your system is 12V DC. Some fixtures are 12V directly, while others may require a transformer for AC use.
- Size and fit: Measure ceiling cutouts and space. Slim profiles save headroom in tight RV ceilings.
- Brightness and color temperature: Consider lumens per fixture and CCT options (2700K–5000K) to match cabin ambiance.
- Dimming options: If you want dimming, check for a compatible 12V dimmer and wiring requirements; some dimmers are sold separately.
- Mounting method: Recessed mounting provides a clean look; check whether springs or screws are included and if panel access is needed.
- Durability and heat dissipation: All-aluminum housings improve heat management in enclosed spaces.
- Warranty and installation: Look for straightforward installation and clear instructions; non-included transformers or dimmers may affect compatibility.
