I have tentatively ordered a LED to replace 20W halogen and am thrilled. On the package are 2 W instead of 1.5 W in the description, but that is negligible compared to 20W. The LED is as bright as the old halogen light, minimal "colder" - but not cold white. I run the LED easily to the old toroidal transformer and just finished watching 2 x 10 piece (much cheaper) ordered the remaining halogen lamps replaced.
