Over driving Pc Bulbs ( is it possible )

[Toooloud]

Im asking becouse i have a setup 2x55 wat pcs.. now the bulbs are about 5 months old.. and the 65k one just died so i have the actinic left..

after this one dies im going to VHO so i will use this balast for that its a workhorse 7 ... so i will run the one 48 inch VHO actinic on it. so untill then i was wondering if i could use this balast to overpower the actinic untill it dies..

can i .. how would i!
