Very good replacement for halogen

The LEDs are good or less suitable depending on the use. In lamps with shade, where through the screen of the color will be affected, they are good. With open radiating the light color is rather moderate. So you can give no general judgment.
For my purposes, they are well suited. The brightness, I would classify with 15W halogen equivalent. 20W certainly not.
Since I had the thought already in the purchase, they fit perfectly with me.
I can therefore recommend taking into account the above points.
