Joule Lamp

[b_rads]

 
Now I can put an unknown light source in there, such as a bulb during Lynx-Lamp testing, and actually measure the Lumens!  I will be able to tell HOW MUCH the light is actually getting brighter or dimmer as I change things like the tap on the primary.
(PS == Not hard to build a light-box! and easy to calibrate.  I think Nerzh said he is building one.)

OK - you convinced me, ordered my lux meter today and will put together a box like yours to test in.  Graphing the light output along side the wonderful graph that Lynxsteam did will be very interesting.  Thanks for the graph Lynx, I think it is starting to sink in what is happening in this build.  This is all very new stuff for me and takes a while to absorb.

Did I say that this build makes no audible noise that I can hear,  haven't asked the dog yet though.

Here's my report on primary wire. 

I tried the following with 4 LED bulbs:
Twisted 18 awg magnet wire then 30 turns on secondary.  High amp draw 2.2 amps, very poor light and hard to start
1/4" copper tubing spaced evenly, 30 turns, "nothing nada zip"  no startup, no amp draw - dead
4 - 14 awg stranded insulated wires in parallel for 30 turns completely filled length - high amp draw 2.6-  amps - moderate light

Next up:
10 gauge stranded insulated (diameter as big as a soda straw)
12 gauge stranded insulated
14 gauge stranded insulated
18 gauge stranded speaker wire with very heavy vinyl insulation

I will try primary turns at varying distances to the secondary.

Its funny, my first tries were the best and I have gone downhill since.  I'll put results in a table to help sort out the different variables.

Good news, Brad!   I believe that those Observations which are Measured and Recorded will Accelerate Progress.  (OMRAP?  )

I also found with some google searching that the world-record for light output from LEDs is right around 140 Lm/W.  (If anyone finds a more up-to-date world-record, pls let me know.) 

So -- if we manage somehow to get ABOVE 140Lm/W, and it is verified, then that would suggest an anomalous source of energy coming in...  see?

Great circuit,
but the problem is, that CFL lamps,
if they break during lighting
put out immense vapours of Mercury, which is very poisoneous !

See this German language movie,
where a little child  slept below a broken
CFL lamp and was poisoned by the mercury vapours and now
is very ill:

So be very careful not to break the CFL or Fluorescent tubes,
otherwise your flats will be polluted with Mercury vapours !

So we should better go to LEDs.

But we need to buy these warm light LEDs, around 2700 Kelvin.

The bright white LEDs, with around 5000 to 7000 Kelvin are dangerous
for your eyes ! They have too high spectzrum bands in the blue area
which is not healthy for your eyes !

One of the best new LED lamps is the new
LED light bulb from Philips,
which also recently won the L-Prize.

It is the Philips EnduraLED.

It is the direct replacement for a 60 Watts incandescent bulb and
you can´t see a difference in color rendering.

I duplicated your turns/power results exactly with that same bulb.  I tried a couple other things.  I was able to start and run the bulb with 13 turns when they are stretched out the length of the secondary for .325 amps.  No big deal, same power draw, but interesting.

I also played with Tesla's Parallel winding.  Take two wires of equal length and put 14 turns on the secondary.  Take one start and connect to the other's end to form the Tesla parallel winding.  I was able to drop power to .085 amps.  Its not bright at all but its interesting.  Now remove the bulb and look at power draw.  That energy is going somewhere.  where?  Now try a large tube florescent and touch one end to the secondary wire, leaving the base wire unconnected.  This is a Tesla coil.  With a 40 watt tube, power draw was .220 amps or 2.4 watts.

I find this interesting because normally with a Tesla coil the primary is a small loosely coupled coil at the bottom of a tower.  You can get all the classic Tesla Coil phenomenon with this LJL.
