  1. Hey everyone, Just wondering if anyone has any idea whats going on in my grow room in terms of my Hps lighting. So... 600w sunmaster dual spectrum bulbs in cool tubes from ebay, second hand powerplant magnetic ballast (manufactured late 2008). The cool tubes are not connected to any form of extraction and are hung horizontally so im wondering could the bulb of overheated inside the reflector? This is the second bulb that has failed in under 200 hrs-ish now. First time I didnt see what happened but I went to switch on the lights today and the two electrodes closest the cap were arcing like plasma with white flashes which then proceeded to glow orange and fail. I think the first bulb may have failed due to the ballast's internal connector block being charred badly to which the wire had barely any connectivity (fixed). The internal tubes connecting points (marked by yellow arrow) had decayed both sides and looked like white ash... litteraly. Any help or ideas is greatly appreciated. The FiSh. P.S. How do I post photos?
