Sun system 2 hps problems !

Ok probably noob question but I just got sun system 2 mh / hps for my 3 flowering girls and my 12/12 from seed us dreams ... Well I somehow unplugged timer out wall.... Which has happened before but this time when I went to plug it in NO LIGHT.. I tried turning off and on but eventually switched to mh and put bulb on it works .... But I was reading some people have to wait 20-30 mins then there light will kick back on.. Anyone have any experience with this :// got me thinking my hps is out forever but hoping just needs some time off or something the mh is on now tho Thanks n advance

mine takes about 5 mins to come back on after being switched off

dont switch back right away, wait 10-15 minutes.

I love you guys !!! at RIU lol i switched back to HPS this morning before timer kicked back on and hortilux turned right on awesome i over react real easily haha the "not knowing" factor kills me thanks though i appreciate the feedback
