The LumenstarLED RD33 belongs to a class of low-voltage inground uplights engineered for precision landscape lighting. Operating at 12V DC, this fixture is compatible with standard low-voltage landscape transformers, simplifying system design and installation. Its compact form factor allows it to be discreetly flush-mounted into grass, gravel, paving stones, or soil, providing powerful upward illumination without visual clutter during daylight hours.
At just 3 watts, the RD33 is an energy-efficient solution that keeps operating costs low without sacrificing light quality. The CRI 90 rating places it among the top tier of colour-accurate light sources, ensuring that foliage, stone textures, building facades, and decorative elements are rendered with exceptional fidelity. This makes it an ideal choice for projects where visual impact and colour accuracy after dark are priorities.
The 3500K warm white colour temperature strikes the ideal balance between the warmth of a traditional incandescent glow and a crisper, more contemporary neutral white. This tone is widely preferred in landscape and architectural lighting for its ability to flatter natural materials like wood, stone, and foliage while creating an inviting ambiance in outdoor living and entertainment spaces.
Constructed with a stainless steel housing and trim, the RD33 is built to withstand the rigours of Canadian outdoor conditions — from freeze-thaw cycles to heavy rainfall. The IP67 protection rating confirms complete dust-tightness and the ability to withstand temporary immersion in water up to 1 metre, giving installers and property owners confidence in long-term fixture integrity even in the most challenging wet locations.
The RD33 ships with a 24-inch (60 cm) lead wire for flexible low-voltage wiring connections, and its ETL listing confirms compliance with North American electrical safety standards. Backed by the LumenstarLED brand's commitment to quality, this inground uplight is a trusted solution for landscape contractors, lighting designers, and property developers seeking reliable, high-performance outdoor illumination.
