I've been setting up my tent this morning an when i got round to connecting the lights up(im using 2x600w once ive got the plants around 12" inch tall) only 1 light came on...I gave the "not working" ballast a shake an could hear somet loose inside,I unscrewed the top and found this...
I best get the spare ballast out
This could have been deadly! Please remember ELECTRICITY is DANGEROUS people!!
