Nice bright little lamps for their power size these.

I like these LED filaments as they are so much like proper tungsten lamps.

I have just put a load of these under my kitchen units, you would be surprised at the slight colour shift between them, reflected on the wall?

I noticed that as well. Seems the light gets refracted somehow.

Yes there appears to be an escape of blue light from the edges of the 'filament' strips. Presumably from where the phosporescent yellow plastic layer meets the strip? I am sure these minor flaws will disappear in future lamps, still in the early stages of this technology when you think about it...
