V-TAC VT-7779 LED Ceiling Light, 18 W, 4000 K, 1280 lm, Round, Black, Ø35 cm

Name: V-TAC VT-7779 LED Ceiling Light, 18 W, 4000 K, 1280 lm, Round, Black, Ø35 cm
Brand: V-TAC

The VT-7779 is a flat LED ceiling light from V-TAC's Designer series — a round disc 35 cm across and just 6.2 cm deep, finished in black. The build combines aluminium and steel with a PMMA (acrylic) diffuser that spreads the light evenly across the whole face — from below you see a uniformly lit circle rather than individual diodes.The lightAn 18 W LED module delivers 1280 lm at 4000 K — neutral white, which does not yellow a room the way 3000 K does, but is not as cold as daylight either. That is a sensible output for general lighting in a room of roughly 8–12 m², a hallway, a corridor or a bathroom. Efficacy works out at about 71 lm/W, and colour rendering exceeds CRI 80.What to expect — and what not toThe fitting is not dimmable: it runs at full output and will not work with a dimmer (within the same series V-TAC labels its TRIAC-dimmable models separately). There is no colour switch either — 4000 K is fixed at the factory. The LED module is integrated and not replaceable; once its life is up the whole fitting is replaced. The manufacturer declares 20,000 hours, which at three hours a day is roughly 18 years.Data from the EPREL registryV-TAC registered this model in the European energy-label registry under number 1498857. The manufacturer's declaration gives energy efficiency class G, a lumen maintenance factor of 0.96, an R9 index of 12 and colour consistency of 6 SDCM — if you install several units in one room, small differences in the shade of white may be visible between them. The declared flicker metrics are PstLM 1.0 and SVM 0.9.InstallationThe fitting is surface-mounted on the ceiling and wired directly to 220–240 V, 50 Hz via an L/N connection — no external driver or transformer is needed. The IP20 rating restricts it to dry rooms. Manufacturer's warranty: 2 years.SpecificationsManufacturer item: VT-7779B-RD (V-TAC SKU 6986)EAN: 3800157698719Type: LED ceiling light, surface-mountedPower: 18 WLuminous flux: 1280 lm (about 71 lm/W)Colour temperature: 4000 K (neutral white), fixedColour rendering: > CRI 80 (R9 = 12)Colour consistency: 6 SDCMDimming: noneSupply: AC 220–240 V, 50 Hz, L/N connectionDimensions: Ø350 × 62 mmMaterial: aluminium + steel, PMMA diffuserColour: blackNet weight: 2.1 kgProtection rating: IP20Energy efficiency class: GDeclared lifetime: 20,000 hEPREL number: 1498857Warranty: 2 yearsMostra di più
