Is that only for 240 volts or can it work on 120v? 18 watt fluorescent isn't all that common around here... Also any idea on how to run the 55 watt lamp?
Here is a basic rundown on how it works:
Many years ago when Sox was common we used dedicated chokes (I’ll post a pic soon).
18w Sox is 57V and 0.53A. 18W fluro is also 57V and 0.53A, they are electrically identical
The fluro choke will work on both 120V and 240V.
I’m not sure the starter method will work because the low voltage starter or the series ones will make the lamp cycle so I use an FSU for 250V you can use a low voltage igniter for MH lamps.
You can use 18/20W fluro choke.
55W is different and you have to use a dedicated choke because there is no alternative
