The STELLA 5 is a compact architectural façade spotlight manufactured by LIGHT TECHNOLOGY LLC under the Raduga Light brand, a Russian producer specialising in professional outdoor and architectural luminaires. Consuming just 18 W, the fixture produces a maximum luminous flux of 1,980 lm with a colour rendering index above CRI 80, making it effective for accent, wash, and grazing light on building exteriors, monuments, and landscape features.
The housing is precision-formed from anodised aluminium and sealed with tempered glass, achieving an IP67 rating that guarantees complete dust exclusion and protection against water immersion — a prerequisite for permanent outdoor mounting. An operating temperature range of −45 °C to +40 °C with climate class UHL1 certifies the fixture for the full breadth of Russian climatic conditions, including severe northern winters.
Optical flexibility is built in: six selectable beam angles — 3°, 8°, 12°, 24°, 36°, and 60° — cover tight spots through wide grazes, while colour-temperature choices spanning 2700–6500 K together with RGB and RGBW variants allow tunable white or full dynamic-colour effects from a single product family. Professional control via DMX512 or DALI 24 V DC enables direct integration into building lighting management systems.
The wall-mounted unit measures 215 × 183 × 63 mm, weighs 1 kg, and ships in a standard RAL 8022 dark brown finish.
