This Philips color light swings downward, and the 3-pack includes 3 wall lamps that bring color to your garden. These lamps feature a downward-facing triangle that you can adjust to be wider or narrower with the included clamp. For example, you can create a playful effect. The lamps are quite small and subtle, making them suitable for any garden. This lamp offers 16 million different colors and every shade of white light. The lamp is made of aluminum. You connect the lamps to your Hue Bridge, after which you can operate them anywhere and set fixed routines. The light source is built-in and therefore not replaceable. You connect the lamp to the mains, so a power cable must lead to your lamp. Note: You need a Philips Hue Bridge to use this product.
