angel eyes kit ccfl from RDASH (a little pink)

[aliman]

hello

I just bought today an angel eyes kit from RDASH and when i test it i saw that the big rings on the down part they are a little pink. The intensity of the colour is not the same ... from up where the neon start is bright white but when you go down the tube the intensity of the colour is decreasing until the colur is a little pink.
have you got the same problem or is just the problem of my kit ?
I said that maybe because the big rings are really big so the round tube is long is this decrease on intensity of the colour from bright white to pink.
The small rings are just fine nice colour but the big ones are with problem.
