I understand that Mars, Spiderfarmer, Bloom Plus and possibly others are all made out of the same factory and i have had some bad experience with Spiderfarmer and they are not very helpful if there is a problem. Meanwell drivers and Samsung diodes but made very poorly and the dimmer/control units are likely to fail. I have bought 3 Bloom Plus lights and while they do not have the higher end driver and diodes but they have worked great for years and never let me down.
I have just purchased Mars some FCE3000 FCE4800 and FCE8000's. Got a good discount so its worth checking them out.. They have a Marshydro driver which scares me. They did have Moso drivers originally but were swapped for inhouse to save money... I have learnt that if you buy them on ebay you are covered and they will look after you only until the time that you have left feedback or can no longer do so.. Then they become difficult and are reluctant to take a hit for the warranty.. Time will tell if the components last but to be honest i have done a lot of research and not found a whole lot of complaints.. I suggest you see if you can fit a new driver, being out of warranty i am sure they won't deal with it but you might be able to purchase one from them.. It's a Chinese factory/Company so if your product did last the warranty you have done ok with it.. I will be verry happy if mine last the 5 year warranty they give it.
