Luceco Smart LED Candle Lamp with a Small Edison Screw E14 cap, 6W, with colour change. The candle envelope suits chandeliers, wall brackets and multi-lamp fittings, which is where smart control earns its place because those fittings are often on a single switch and hard to reach. Controlled from the BG Home app on a phone or tablet, and by voice through Amazon Alexa and Google Home. Lamps mesh together, so one lamp within range of the network carries the others and no separate hub is required. Colour temperature adjusts across the warm to daylight range and the lamp dims from the app without a dimmer switch in the wall, which is what makes it a retrofit rather than a wiring job. Operates on a 220-240V supply.
