3.7 VOLT BATTERY POWERS 56 WATTS

Just a cardboard box... no real leaks but no insulation ,the loss to ambient will be the guide here [final temp rise against  losses]

if DUT test gets hotter than control test running on same power input.
example
ten watt resistor will only raise temp in box to an ultimate temp against losses
if DUT makes Box hotter [same box same ambient temp] with less power than control test.

you have something to qualify the claim, caloric measurement is a rock solid science

I always like to run tests side by side [same size box at same time]

your suggestion is not being dismissed here ,its just that cardboard boxes and thermometers are everywhere, not everyone has a Lux meter [or needs to buy one]

and it can be done in minutes ,and once done it can be used to measure advancements

Okay Chet, I understand, it indeed sounds simple and accurate.

On the lux meter:  if someone has such meter he places it near to the lamps on the table to have a steady value displayed on it in a position and from then on the meter remains untouched during the measurements. Then with a alternative switch the LEDs could be switched by hand to be fed from either the setup output or from directly the power supply.   
When there is no lux meter available, even an eyeball brightness comparison could be done to get a reasonable estimation of the power level coming from the power supply because in this setup a COP of 10 is involved.   (what I doubt, sorry)

Thanks

Hi All,
Thought you might want to see the below experiment:

https://www.youtube.com/edit?o=U&video_id=zwu0RZ2pkjw
A 1.5 volt battery is powering 9 seven watt, 12 volt, led bulbs now through my setup.

I am now open for a substantial offer on my entire setup. I have all extra parts to exactly duplicate it.  Then whoever purchases it can run all the experiments suggested by others and I can take a rest while others put in their time and take it further.
Whoever needs it also buys about 150 pounds of different experimental parts that were accumulated leading up to the present setup. Need a pickup truck to haul all away unless you opt only for the setup itself.  I live in Michigan, USA  Pay Pal only PRIOR to purchase.

your link {you tube] seems broken ? although it could be my end.
