I'd use radiosity with a count over 300 for test, probably 1000 or more for final
render. It's 
obvioues that render time will be long. You need high count, because the tubes are
narrow and a low 
count will miss them to often leading to dark patches where it should be bright.
As the tubes are transparent, using emiting media should be considered, but this will
also increase 
rendering time.
You may want to remove or reduce the light inside that globe, it will make the light
enited by the 
tubes more visible.
Set default finish to ambient 0 with #default{finish{ambient 0}}.
