The 13W V-TAC is compared to the "aged" OSRAM significantly lighter and should meet me at least a 80W light bulb. The light I find something white (possibly lies also in the brightness), than with the predecessor. Contrary to my previous experience with LEDs the light color and distribution is very good. With direct views of the Globe, I can make no disturbing light source on the frosted screen Globe. The maximum brightness is achieved immediately after switching on.
For longevity, I can not write anything yet, because with us until almost 2 months in use.
