What “Low Voltage” Means
Low-voltage post cap lights are 12 V LED lighting fixtures that require:
- A low-voltage transformer or power supply (often mounted under the deck or near an outlet)
- 12 V wiring that runs to each post cap light
Optional quick-connect pigtails to make wiring and future replacements easier
Ideal Garden Lights
This setup is noticeably safer and easier than standard line-voltage wiring because the 12 V system is low risk and many deck lighting kits are built around it.
Typical Features
Warm LED glow: Most low-voltage post caps use LED panels or bulbs that emit warm white lighting (~2900–3100 K), creating a cozy, inviting ambiance.
Ideal Garden Lights
Cast aluminum or durable housing: Most fixtures are built with weatherproof powder-coated aluminum and real or frosted glass panes, which stand up to outdoor conditions.
Ideal Garden Lights
Hard-wired installation: These are not solar — you’ll run a transformer and wiring to provide power, though many come with quick-connect leads to simplify installation.
Ideal Garden Lights
Multiple post sizes: Many styles fit common post dimensions (2″, 3½″, 4″, 5″, etc.) — check specs to match your posts before purchase.
Installation Considerations
✔ Transformer & wiring: You’ll need a low-voltage transformer and properly sized landscape wiring to connect all post caps.
✔ Dimming & control: Many low-voltage systems can be dimmed via a DC transformer or controlled with an accessory wall switch/photo sensor.
✔ Series or parallel wiring: Lights can be wired in series or parallel depending on your layout, but landscape-grade low-voltage wiring is recommended to minimize voltage drop.
✔ Pro measurement: Always measure your post actual dimensions (not nominal) to ensure the cap fits snugly.
Why Choose Low-Voltage Over Solar
Brighter & more consistent light: Low-voltage LED typically offers more reliable, longer-lasting illumination than many solar post caps.
Central control: You can integrate these into a central lighting circuit with photocell, timer, or switch control.
Design flexibility: With a transformer and wiring, you’re not reliant on direct sun exposure for power — useful in shady deck areas.
Summary
Low-voltage post cap lights from Aurora, Dekor, and similar brands are hard-wired 12 V LED lighting fixtures that cap your deck or fence posts, providing ambient, warm illumination along outdoor spaces. They’re built with weather-resistant cast aluminum and glass, and while installation takes more effort than solar lights, they deliver consistent brightness and design flexibility for deck lighting schemes.
