How it works

The Lunaro Halo does two jobs. During the wind-down it projects a scene across the ceiling. Once your child is settling, you switch to the warm amber glow and leave it on all night.

Setting it up

1. Plug it in. Use the USB-C cable and UK plug in the box. It also runs from a laptop, a power bank or a car USB socket.
2. Place it. Somewhere 1 to 2.5 metres from the ceiling works best: a nightstand, a shelf or a chest of drawers. Closer gives a smaller, sharper image. Further gives a bigger, softer one.
3. Choose a scene. Slide one of the five discs into the lamp head until it clicks.
4. Focus it. Twist the ring around the lens until the stars are sharp. This takes about three seconds and makes a bigger difference than anything else.
5. Aim it. Bend the arm towards the ceiling, the wall, or straight over the bed.
6. Dim it. Hold the touch button to move through the brightness range, from a whisper to a full sky.

Getting the best out of it

• Turn the main light off. This is not optional. It is a lamp for the dark.
• Close the curtains in summer. In June a British bedroom is still bright at 9pm. Blackout blinds transform the effect.
• Aim at a plain part of the ceiling. Coving and light fittings break up the image.
• Use the warm mode as the sleep light. Warm amber light interferes with melatonin far less than cool white or blue light, so it is the better choice for the hours after they drop off.
• Rotate the discs. Let them choose tonight's sky. It turns the light going off into their decision instead of yours.

Looking after it

• Keep the discs in the wallet. They are the one part that scratches.
• Wipe the lens with a dry microfibre cloth. No sprays.
• Do not force the arm past its natural bend.
• Indoor use only, and keep the cable away from a cot.
