LJLsc

I love this forum, what a massive bank of minds and producers.
Its my first post but trust me I have read and re-read and read
again nearly every post in this forum....
I have built several LJL's now and I think each one works
great....even the big LJL with 3 secondaries of 20awg works
great. I am posting this to see if anyone else has had similar
results. My latest 2 LJLsc circuit pull a lot of Amps while
using the 6 Watt bulbs but when I hook up 10 Watt bulbs those
little jewels shine, I mean they work fantastic. I will try to
post a video to show what I mean.
this one in the video is 30awg magnet wire from RS (Red) both
primary and secondary it has a 14:100 ratio it still has a diode
bridge but no ferrite choke. When I have the snap on ferrite
choke on it makes the lights brighter but draws more Amperage so
I left it off. It is had to see in the day light but the bulbs
are very bright.
Here is the address

thanks for your input,

They are eco smart bulbs from HD and both of the types are
blazing bright, I have 2 that are daylight, and 2 that are
bright white in the 10 W, and the 2 that are 6W are bright
white. I can not run the 6w and the 10w on the same circuit at
the same time.
Thanks

Thanks CG, I will build a rectifier tonight when I get home,
I'll post results when I get it completed..
Thanks again. M

Never did get any of these to work on my cfls but then again I
never did stick at it and really try. The driver built into led
lamps is the main cause of success/failure in my opinion and
dictates the current draw. (Just my opinion)
Fantastic video Mike and welcome to the forum.

Yes CG is very much a "Ham" - maybe no radio : )

HGL
The coil I show is made up of #30 magnet wire for both primary
and secondary (14:100). I can run 6 W eco smart bulbs but not at
the same time with the 10 W bulbs...unless I remove the diode. I
just re-ran the test without the diode and it will light up both
sets of bulbs at the same time but my amp draw is much higher. I
tried it with 3 other LJLsc coils that I made and it shows
similar results on all three. I have one that is #20 wire for
both primary and secondary(14:100) and another that is #30
secondary and #26 Primary(14: 75) the (14:75) coil is tuned to
work perfect with the 6 W bulbs, I don't know how many it will
light up, but it will run 2 for 2.5 hours on a 12 V Milwaukee
drill battery at full brightness. This coil will not light up
the 10 W bulbs the way it is tuned but once the diode is removed
it will also light those10 W bulbs at 1/2 brightness. I have
found that none of my LJLsc's like to light up bulbs with a 9v
battery but that is ok because i am using a 12v system. My big
LJL works with any battery 6v - 18 but it will over power bulbs
with the higher voltage so I use it on 12 Volts most of the
time. All of them light CFL bulbs but with a very high amp draw
so I leave those bulbs alone....for now. As for the Amp draw on
the coil in the video on a 10 W bulb it pulls 280mA and on a 6 W
bulb it is pulling 800mA, so it is over driving the 6 W bulb a
little and under powering the 10 W bulb but using a photo cell I
measured the difference between the two resistance values and
the 10W bulbs are putting out about 2/3's the amount of light
that the 6W bulbs are....I am satisfied with the results by not
over powering the bulbs I get great light but I will tune the
rest of the LJLsc units for the 6 watt bulbs because i found the
difference in price on the bulbs is my deciding factor.
@CG I have the rectifier but I have not run the test with it
yet.
