Well, I had high hopes for this bulb but it turned out to be an inappropriate purchase for my room. I was using 2 x3 bulbs in two different top light fittings in two parts of the same room. Sadly the lumens are not sufficient and the room now looks very gloomy and sad (bit like a comedy goth house). The light is very nice and soft (much nicer than with other LED type bulbs), but it is just too low. I am going to have to replace the set. I am sure if I had looked at all the details I could probably have worked this out, but I just never considered that 6 dimmable bulbs would be insufficient to the task when up full.
