Positives:
Quick uniform light, economical production. (I hate to saving lamp to wait ...)
A humming or other noise I could not tell.
Weight 43g is easy enough to find a place in a Schwenkarmlampe.
Beam angles: Absolut as a dull bulb.
Neutral:
Well, warm light. I like it, but unfortunately it is not particularly well suited to work. At the desk a pear belongs in the cold range. The increased attention and easy on the eyes when reading. Unfortunately this bulb even a trace is too weak after my feeling for reading.
Negatives:
The yield of 6Watt is consumed which this bulb is not particularly large. Maybe it's the elaborate warm light output?!?
Conclusion: Wonderful in the cozy living room / kitchen. Go at a moderate distance sometimes to read (nightstand?)
Current / light output: if you let them run long, you should possibly look for even after efficient.
