ah bigsby
you came back with an answer within 5 min... record in my book.
you and me sort of had this talk before, but i thought i would refrase my question to see if anyone knows anything.
thanks for getting back to me. the cooltube,i have read somewhere takes 3-5% of light true reflector,but even worse its meant to have a very bad light spread.
I had thought about it though.
