rays of light seem to me sweats and represented clumsiness :) That is why I dragged it as non-interested. If you work on the rays it may be ok. But also I have a concern about bulbs. Using a bulb as an emblem hit me at first time, but electric bulb is also an emblem of a political party in Turkey. I do not want to be seen as a supporter or fanatic of that party. If it is morphed right, and does not represent as in your example It can be used.
