Plafond V-TAC 18W LED SAMSUNG CHIP Round 30cm Surface Mounted Pilot Motion Sensor IP44 Black VT-8618S 4000K 1830lm 5 Years Warranty

The VT-8618S is a round V-TAC LED dome light with a built-in motion sensor, designed for surface mounting on a ceiling. Its black housing is made of PP plastic with an acrylic (PMMA) diffuser, measuring 29.5 cm in diameter and 6 cm in height.

How much light it gives, and what kind

The light source is a built-in Samsung LED chip rated at 18 W with a luminous flux of 1830 lm, giving an efficiency of 100 lm/W. The light colour is neutral white at 4000 K — between warm and cool white — and a CRI above 80 gives colours accurate enough for everyday use, though not for tasks that need precise colour matching. The diffuser spreads light across a full 360° with no directional beam.

How the motion sensor works

The fixture has a built-in microwave sensor operating at 5.8 GHz that detects motion within a 2-4 m radius of the fixture (maximum detection distance is 8 m); the manufacturer recommends mounting at a height of around 3 m. The light switches on automatically when motion is detected, but only when the room's ambient light falls below about 30 lux — in bright surroundings the sensor won't trigger. After the last detected motion, the fixture stays lit for one more minute before switching off.

Build and where it's suited

The IP44 rating allows mounting in places exposed to splashing water, such as a bathroom, and in hallways — both uses are also listed by the manufacturer. The housing weighs 0.77 kg, and the energy efficiency class is F. The manufacturer states a light-source lifespan of 20,000 hours (about 18 years at 3 hours of daily use) and more than 15,000 on/off cycles, which matters given how often a sensor-driven fixture switches. The fixture carries a 5-year manufacturer warranty.
