I have 2 of these fixtures, in the last year I've replaced.. 
 
-all bulbs T5 and Mh 
- all ballasts T5 and MH 
-Leds quit but not worth replacing 
 
Doesn't leave you with much left besides sub par reflectors. After the cost of replacing all 4 MH ballasts and the 2 T5 ballasts I could have easily bought a quality fixture..
