Lamp with good light output, minimal subjectively weaker than a 20W halogen bulb, but by the minimal whiter color spectrum (compared to halogen) it makes up for that weakness. Star deduction there, however because of the huge size compared, which makes it compatible with many, but filigree G4 socket lights problematic because the bulbs oä survives from the lampshades and so destroys the optic. Why this lamp has to be big, do not open up to me. For me, a knock-out criterion, I have decided for the same manufacturer smaller lamps.
It is important to note that you necessarily have to replace the old halogen transformer, otherwise there is frustration by flickering or not aspiring lamps, due to the need in many transformers minimum load, which is not reached by the LED lamps usually! So this is not a product defect but requires a transformer exchange!
The product is provided for testing by the manufacturer; nevertheless I give reviews from the best of our knowledge and belief. :-)
