Hey FranJan thanks for that. The off the shelf idea sounds interesting as I do not have a warranty, I got it second hand from ebay-the seller has since "left", and so am unsure if they could help me, however I took your advice and dropped them an email, so fingers crossed on that one-I appreciate the link .To be honest I never really wanted to know about what the inside of an led growlight looked like, I just wanted to concentrate on the growing, but when you pay alot of money for something just to break at a crucial stage-I guess you just have to try your best and fix it yourself- and thats where you kind people come in. So if I can ask you about these drivers on Ebay, FranJan?- do you know from your experience what wattage of driver these are on the BS?-they are absolutely non descript apart from a label on the casing that reads: 80-130v 630mA. I think its string of approx 42 leds that cant be lit until I can get the replacement-so Im currently left in limbo.Thanks
