Joule Ringer!

No ringing at all. I got even brigther light when the primary is 51 turn and the amp draw at 1.250A but I decide on this final set up since it just for emergency. My goal is getting lowest amp draw. Now I build the other circuit with 2 ferrite glued together so I get the wider core area and I just finished the winding, 960 turn of 0.2 mm and 72 turn of 1 mm solid but I heve not test yet. I will updated here once I get tested

  Thanks again for the info. I took the liberty of placing your last picture and comments on the Energetic Forum, as I think that you have a nice replication to show, as well as explaining how you made the build.

Hi guys,
Here my boxed SJR 3.0. CFL 220 V 18 Watt. 1 Amp drawn.

As a simple comparative measure, have you tried putting another CFL 220v 18 watt lamp connected to the mains supply (as it normally would be) next to your SJR.?

Just a thought.

Cheers

Here video of my SJR 3.0. It light up 2 CFL (18 watt & 11 Watt) and 3 LED bulb (3 Watt and two x 1 Watt).

@Nickz,
Thank for your effort to share my SJR 3.0 on EF.
@Hoptoad,
Unfortunately I just have one 18 Watt CFL, but when I hooked Up 18 W CFL to the grid the amp draw was  120 mAmp.

Hi Guys,

I just build mini SJR 3.0. I am using inductor from burnt CFL. It contain around 200 turn of fine magnet wire ( I think # 32 or #34 gauge). I just add the 30 turn of 0.2 mm mganet wire primary coil over it. This thiny SJR able to light up 5 Watt Un-gutted CFL. It draw 400 mA. I put all part inside a E-37 fitting.
