Compared to my old 300W halogen bulb (I believe it is 300W), the illumination difference is really huge. This LED module illuminates much worse than the halogen. Also, keep in mind that the color of the LED cool white, so very far from warm white halogen (it surprises!). It therefore has a rather pleasant effect in my living room, as close to natural light, and is sufficient to illuminate the entire space (~ 20m), but a much less warmly.
My lamp is straight and not tilting, it might not be ideal. Choose an adjustable floor lamp, you will surely get much better rendered lighting (a big part of the light is lost on the ceiling in my case).
Maybe a bit expensive, but for the energy saving, it is most likely profitable quickly. A little more power would have been nice.
