The light output is better than the 20 watt MR-11 I replaced, and of course it's a blessing to minimize relamping of tiny MR-11s. Since LEDs have "faux" dimming, it's not as continuous, full range and even as analog dimming of halogens; and it won't dim below a certain minimal level.
Pros:minimize relamping--efficiency. You can get more lumens out of a fixture normally limited to a 20 watt halogen.
Cons:It does not have full range dimming like the halogen
