hello my HQI fixture stopped working yesterday, the T5's built in the fixture still works but for some reason the HQI is not turning on anymore and I don't know if its the bulb or the ballast. is there any way to check the bulb or ballast to see if its defective before I go buy new ones? my plan is to buy a new bulb and if that doesn't work then proceed to buy a new ballast for the HQI. however If it is the ballast is there ways to repair it or am I kinda screwed here? im a college student and I don't have the money for this however if I don't do something soon my HC carpet will die off. please help
