This lamp is really barely larger than a conventional G4 pin base lamp and delivers about as much light as the old satin 20W lamps. Due to the small dimensions and the closely juxtaposed LEDs and the appearance of my lamps is largely unveränmdert: A diffuse spot of light behind the frosted glass and not a lot of small dots. Also, the light color is in line with halogen correspond largely - even if the individual lamps differ somewhat from each other in color and therefore also in the brightness impression.
I hope the durability is given - they are Doll hot with me at least not what I always worth a good sign (classic 12V AC copper toroidal transformer).
