Oscillator Powering 6 Modified Led bulbs

[magnetman12003]

Hi magnetman, that looks like a useful boost converter.
Not sure it's as efficient as the one i have, though the description on mine says up to 95% efficiency, where this one states 85% efficiency.
So mine is probably around the same efficiency.
What experiments do you plan to try.

I am going to try lighting 9 seven watt 12 volt bulbs with 36 volts then try three  115 volt 10 watt bulbs in parallel.  I just bought that 900 watt booster converter.  Then I will modify the bulbs and work it that way.

In all cases I now have standard illumination figures to go with using my candle power meter.
So now I can compare a bulb illumination to a standard and adjust the setups output till I have the same candle power reading.  Then compare both results as far as what voltage, current. and watt values have been established.

Hi magnetman, sounds good, look forward to your results.

Directly plugged into 12 07 DC volts ONE 12 volt 7 watt DC led bulb shows a current of .59 amps and a watt rating of 7.1 watts. Candlepower 2040

Directly plugged into 122.3 AC (house) voltage ONE 10 watt AC bulb shows a current of .0809 amps and a watt value of 9.9 watts.  Candlepower 3700

Now by using the boost converter module If can get lower watt values with the same candlepower illumination that will be something.

hello magnetman,
I am really interested in your search findings and results which will hopefully being a success !

I have now your given numbers related some questions :
the AC bulb consumes more power than the DC LED ,
but by candlepower/Watt relationship the  AC bulb gives 370 cp/W
and the DC  LED 290 cp/W.
Correct ?

cd(Candela) versus lx(lux) versus lm(lumen) definition

What do you mean with "candlepower"/"sterian candlepower" and how do you  measure your light intensity results ?

12,57 (4 x pi) Units lumen = 1 Unit (sterian)candlepower :
your given candlepower (3700 and 2040) numbers multiplicated with 12,57
or AC bulb 3700/(12,57 x 9,9) and DC LED 2040/(12,57 x 7,1) as
                             lumen per Watt

AC bulb : incandescant bulb ? Halogen ?

Sincerely
             OCWL

        nice numbers which are actually only surpassed by the Cree LEDs
        and Phillips Lab LED prototypes 200-300 lumen/W

All led bulbs used. Non modified.  Used hemisphere off a large led bulb and fitted it onto my lux/foot candle meter to have exact clearance from top of hemisphere to top of any lit bulb.
