have you more info for total cable wire length and how many ohm

If you are asking about the coil makeup then here is the info:
740 feet of [two wire] 24 gauge PVC coated wire is needed.  19 ohms should be measured through each wire if correctly cut.  Wind the FACTORY PRE TWISTED  cross connect (name) wire clockwise  starting from the INNER core and stopping at the OUTER outside. Now you have a air core coil.  Spool diameter is 6.5 inches, width is 2  1/8 inch.  The spool and 1000 feet of this kind of wire can be found on Ebay.
This particular spool below is great as it shows two long wires coming out of the core.  All one has to do now is strip off enough wire from the outside of the spool till you have 19 ohms measured and you have a finished coil.  The spool itself is the diameter/width needed.

I just did another system test and found with all bulbs lit brightly I had 6.2625 watts  measured between the 17 watt USB adapter and the setup.  All other system watt values I measured were lower.  So the big question now is how is 63 bulb watts powered by 6+ watts which was the highest value measured ??
Waiting to compare results from anyone who has gone this far.

Hi magnetman,

I would like you to consider the following test suggestion. It would help to check with pretty good accuracy how much output power your setup feeds into the group of your LED bulbs.

You have got a variable power supply as shown in an earlier video of yours. That power supply could be used to drive the same group of LED bulbs directly to achieve the same brightness your setup provides. And if you happen to have a lux meter then the subjective eye ball comparison in the two brightnesses could also be eliminated.

Because your power supply has built-in output voltage and current meters (but you can also use your multimeters to double check)  the power driving the group of LEDs directly from the power supply could be received and calculated that is needed to achieve the equivalent brightness your setup provides. Thus a more exact estimation of the input - output levels can be had.

I understand you wish people replicate this setup, the more the better.  One thing is sure: if the results of your measurements as suggested above reflect similar behaviour for your setup what you wrapped up like this in an earlier post:
"THE REAL QUESTION TO ASK IS HOW IS THIS POSSIBLE CONSIDERING THE FACT THAT CLOSE TO 63 WATTS ARE NEEDED TO POWER THE BULBS? 4 TO 6+ WATTS SHOULD NOT DO THIS??",  then you will surely have your wish fulfilled.

People normally need technically convincing proof to take actions.  I do know you are an honest experimenter, you do have good intentions and your findings seem to refer to an anomaly. This should be proved by all means possible, in a scientific way.

Thanks,

a humble suggestion, caloric measurement protocol ?

a fixed loss to ambient test .

put the bulbs in a box ...measure the max temp the box rises  against ambient losses,[it will peak] note input power
from DUT [device under test]

now run same test off standard power [control]
if DUT [device under test] makes same box hotter with less input power
do the happy dance

very very simple test, have used it many times {thanks Vortex1]

I can ask for assistance here if you wish[to thoroughly explain simple test]

the results once done properly will not be disputable

a cardboard box and a thermometer [instead of Lux meter which may not be as conclusive]

with respect

Hi Chet,

Well, your suggestion would also be feasable I think and a thermally well isolated and closed box should be built for such tests.

I assume the direct DC power input measurement to the group of the LEDs from a clean power supply to get the same brightness (lumen output) the setup feeds into it may be a simple method. 

Obviously, there can be some methods to consider and which is simpler but still able to give reasonable measurement results.  I do not insist on my suggested method,  the goal is clear. 

Thanks,
Gyula
