Oscillator Powering 6 Modified Led bulbs

[casiano]

Hello SkyWatcher.
I replicated your circuit and it works very well,the only difference is i used a different cap and coil.
I used a 5v phone charger and 9 220v led bulbs in parallel.
The question is,why i am getting 280v output from the setup circuit?
And no matter how many led bulbs i add the power consumption is the same.

I just bought a AC to DC 12 volt 8.5 amp  power unit (102 watts) and when I connected it to my setup all
9 of my 7 watt bulbs in parallel with an extra 5 watt bulb included in parallel (68 watts)  go on and off continuously???  NOTE: A regular 12 volt 12 amp hour battery will power all the bulbs continuously.  No on and off.
Just what kind of a AC to DC power unit do I need??  Please indicate on Ebay the correct type of supply I need.  You cant use a battery to figure out accurate circuit parameters as the voltage will start decaying as soon as its used.

Hi magnetman,

Are the 9 bulbs + the extra 5W bulb nicely lit when you directly run them from the output of your AC to DC power unit? i.e. leave out your setup, ok?
From your description it looks like the 102 W power adapter is not capable to supply enough current at 12 V to feed the 12 V bulbs.  And of course you can always do measurements on the 12 V output when you start it loading say one by one with your lamps.

Hi all, Hi magnetman, I agree with the advice of gyulasun.

I have been making some experiments with my dual oscillator circuit that is powering the 8 led bulbs.
It has been working very well for me, when i need a lot of light up here.
So i decided to try the setup using the 3 battery, split positive method to power it.
The input watts to the circuit is normally around 8 watts with the 11.7 volt input from computer power supply.
With this 3 battery setup, that input voltage to the setup does diminish a bit over time, to about 10.5 volts when the charging battery is at 14 volts, yet still allows the led bulbs to output very good light.
Some interesting results so far, using the 12 volt tractor batteries.
I have started the test with Battery A and B in series as the primary input and battery C as the charge battery.
Rest Voltage, batteries have not been used for at least a couple weeks:                     
Battery A = 12.50 volts
Battery B = 12.52 volts
Battery C = 12.495 volts
Overnight Rest Voltage after 3 hour run time:
Battery A = 12.51 volts
Battery B = 12.515 volts
Battery C = 12.725 volts

Seems rather interesting so far, i will be continuing these tests by alternating the batteries to see where this goes.
peace love light

A 12 volt 1.2 amp hour battery and a 12 volt  23a battery will light ALL bulbs powered through my setup???  But a 12 volt 8.5 amp DC power supply cant power all-- just pulse -- go figure??
