theres nothing wrong with a good magnetic ballast, they'll last forever, but they aren't as efficient as a good electronic ballast, and they are prone to leak RF noise, so they can interfere with sensitive equipment, and while they can't be "tracked" the cable company can point to a house and tell that the interference is coming from that house....
you only need a conversion bulb for ballasts that aren't rated for both, yours shouldn't need one...actually not sure one would even operate in your ballast
The breaker never tripped when it switched off,, the dehumidifier pull 22l/day so it's medium size?
I have this one MH bulb that came off a ship, it's 'self ballasting'. A year or so ago I connected it straight to a E40 socket and plugged it in and done a whole veg.. Why don't people grow with these since ballasts arnt too cheap?
The ballast is rated for both, I'll try the other bulbs now and if they flicker, then it is the bulbs that were faulty, if not, it was my power r source that was insufficient
i don't know, never looked into them. i would suspect it's an efficiency issue, or perhaps they get too warm to run in an enclosed fixture?
