good G4 LED,
This review is from: Aurora 12V G4 Unidirectional Capsule LED Bulbs - Warm White - 20W equivalent (Electronics)
I purchased 4 of these to replace halogen 20w under cabinet lights in the kitchen.
They are around the same brightness as the old halogens, but as others have mentioned, slightly whiter, which does look fine in a kitchen.
I noticed a slight flicker when all 4 bulbs were installed. This was down to using the old transformer, which is not rated to to such a low wattage (between 8 and 9 watts total). I had to purchase a constant voltage LED driver, as per the description in Amazon. Aurora do a 16w one which worked perfectly.
Other than that, the bulbs were a little tight in the old housings, but did fit with gentle persuation.
