Both work, but they solve different problems. A smart switch controls the circuit, so it can run a whole group of ceiling lights or downlights, whatever bulb is inside them. A smart bulb controls one light, and it is the one that can change color or shift between warm and cool white.

Vaety. usually puts switches on the fixed lighting, because it is cleaner, more reliable and easier for guests to use. Bulbs go into lamps, accent lighting and the spots where color or tunable white adds to the mood. A switch that controls several downlights at once also often costs less than a bulb in every socket.

If you are not sure which you need, that is the right moment to ask. We map every light in the space, decide the control for each one, and quote per device, so you only pay for what the space actually needs.
