me and a friend both rock Lumateks, he used to have a quantum. all our Ballasts run on 120v.
we have kinda unstable power here, it goes out probably atleast once a month in the winter. after one of these "power bumps" buddy went to check on his tent, which at the time had a lumatek and a quantum running side-by-side. the lumatek was running fine, the Quantum was DEAD.
initial inspection showed no problems, changed the bulb, still no-go.
checked the fuse. WTF. it is a 240v fuse! on a switchable ballast desinged to run on EITHER 120v or 240v input!
it has only one fuse, and a replacement in a little hidey-hole beside the active one. swapped them, both were identical, 240v.
im no expert, but wouldnt a 240v fuse be absolutley USELESS at preventing a surge when running on 120v?
this is the first time i have shared this, so any input is welcome.
other then that (together) we now are running 4 Lumateks and a chinese knock off. the Lumateks seem to handle the power bumps like a boss. i recommend them
