How to assemble your Dyson light

Please follow the steps in the video.

Find the text version of the step-by-step guide instead, under "Is there anything else we can help you with?"

Please select the appropriate option

Getting started

Your box contents will include: the Instruction manual, the Power supply unit, a microfibre cloth, the Horizontal arm assembly, the Fixing pack and the Vertical assembly.

Carefully read the assembly and important safety instructions.

Stand the Vertical assembly on a flat surface.

Remove both pieces of red tape covering the electrical contacts.

Align the screw holes on the plates and press both parts together with one hand.

Loosely screw in the three screws using the provided Allen key.

Ensure the plates are aligned, then secure all three screws fully. Do not over tighten the screws.

Remove any packaging from the base of the Vertical assembly.

Turn the light on its side.

Carefully fit the cord into the indicated groove ensuring it's not twisted.

Place the light upright ensuring the cord remains in place.

Remove the transit tape and all packaging from the product.

Plug in the power supply unit and turn on the light using the button.

The light can be adjusted, vertically, horizontally and rotate through 360°. Adjust the position of the light by moving the arm not the weight.

CSYS lights have touch-sensitive, continuous dimming. Adjust the level of the light you need by keeping your finger held on the button.
