Contemporary Low Voltage 4x4 Vinyl LED Post Cap by RDI
What It Is
The RDI Contemporary LED Low Voltage Post Cap is a modern, lighted post cap that fits standard 4×4 post sleeves (commonly used with RDI railing systems and vinyl or composite post sleeves). It replaces a standard post cap with a cap that integrates a low-voltage LED light— powered by a 12 V transformer and landscape/lighting wiring rather than solar.
These caps are part of RDI’s low-voltage lighting lineup and are ideal if you want consistent, wired lighting for your outdoor space that doesn’t rely on solar.
Key Features
Low Voltage LED Lighting
- Designed for 12 V low-voltage systems (transformer and wiring required; transformer sold separately).
- LED power draw: ~0.8 W per fixture — energy-efficient and inexpensive to run.
- Light color: ~5000 K (bright white), which provides crisp, visible illumination that’s good for safety and ambience.
- Wire lead: Comes with an LED pigtail (about 6″) to connect into your low-voltage wiring loop.
Fit & Style
- Fits 4″ × 4″ post sleeves — common in many deck railing systems.
- Contemporary profile — usually a flat or minimally styled cap with a transparent or clear lens wraparound that disperses the light evenly around the post.
- Simple, modern aesthetics work well with contemporary and transitional deck designs, especially vinyl or composite posts.
Benefits
- Clean, modern look: The contemporary design blends with many railings and post sleeve styles without a bulky light fixture appearance.
- Consistent lighting: Being low-voltage and transformer-powered means you get reliable illumination regardless of sun exposure (unlike solar post caps).
- Energy-efficient: LED technology draws minimal power (~0.8 W), so operating costs are low.
- Safety and ambience: Provides accent and safety lighting along deck perimeters or stair landings without glare.
