This LED lamp with 12V / 4W power replaces 20W reflector lamp in shape.
Here are my experiences:
Positives:

Loose reached + bright and pleasant light that are 20 watts in my opinion
+ The lamp looks beautiful
+ No hum
+ No flickering
+ No (or little) heat development noticeable

Please note: dee LED lamp is not dimmable, dimmable lamps are according to experience but also much more expensive.
