How do i turn a geometry into light emitting body

I want to create cool shape lamps and Led strip lighting in my scene as shown in the picture below

I tried to make a sphere geometry and set it as point light and it isn’t working as i expected it to be.

You can use an emissive material, like MeshLambertMaterial, MeshPhongMaterial, MeshStandardMaterial or MeshPhysicalMaterial. Set the .emissive color and
.emissiveIntensity property.

You’ll probably need to also add some PointLights and maybe a bloom pass.
