light only glows at the ends?

ok, i bought another bulb of the same kind and the same thing happens. could it be the hood?

i also forgot to mention that it is a "aquaglo" and says that the light is 18K. does this mean its SUPPOSED to work like this?

thank you.
 
What watt ballast are you using? All ballasts are not created equal, and trying to power a high watt bulb with a low watt ballast won't work.
