Buying Guide
What to consider when choosing a 12V shower light
- Brightness and color: Choose between warm (2700-3200K) and cool (4000-6000K) tones. Consider lumen output and beam spread for bathrooms or showers.
- Moisture resistance: Look for IP ratings (IP44 for damp, IP65 for splash-proof). Marine and RV bathrooms benefit from higher protection.
- Power draw and dimming: If you need accents or reading light, a dimmable fixture with memory is helpful. Check compatibility with your dimmer system.
- Installation and size: Measure mounting space and wall or ceiling thickness. Surface-mount options are easier for retrofits; recessed options save space.
- Durability and heat: Aluminum housings dissipate heat and extend life. Avoid fragile plastics in humid spaces where UV exposure occurs.
- Special features: Motion sensing, memory function, and multi-color options provide convenience, but may add cost.
