snip...
That is using 33 watts input power from ac grid power, no modifications.
The light from those does not compare, maybe half the practical illumination.
Compared to the boost converter driven, 12 modified 5.5 watt led bulbs, that are only using 22 watts input, which light up the whole room, with blazing light.
peace love light
Reminds me of a line from a 1980's song, I think : " My future's so bright, I gotta wear shades ".


Cheers  ;)

Hi all, just want to share another observation.
I bought a couple 60 watt equivalent GE HD 10.5 watt led bulbs.
I placed those and a couple of 40 watt equivalent 6 watt ecosmart led bulbs into the can light assemblies.
That is using 33 watts input power from ac grid power, no modifications.
The light from those does not compare, maybe half the practical illumination.
Compared to the boost converter driven, 12 modified 5.5 watt led bulbs, that are only using 22 watts input, which light up the whole room, with blazing light.
peace love light

Was the light of the 10.5 watt bulbs observed with the frosted plastic bulb dome covers removed? Your modified bulbs have those removed.    I can see much more light from my 7 watt 12 volt bulbs with the dome cover removed.

Probably  here is a misinterpretation about physical and technical diode use :
we can get physical many lumens(brightness) per Watts input but technical/commercial here is the conditioning :
 8) warranty about durability !  :P and for price comparing !

Cree reports that the LED efficacy was measured at 303 lumens per watt, at a correlated color temperature of 5150 K and 350 mA. Standard room temperature was used to achieve the results.

https://en.wikipedia.org/wiki/Haitz%27s_law
Besides the forecast of exponential development of cost per lumen and amount of light per package
100 lumwn/Watt 2010
200 lumen/Watt  2020

( Our economy is financial costs and profits related not driven by R&D lab physical world records. )


many led lamps are officially given up to 100.000 hours  :) , in our household after +/- 1/2 year in use the lamps have to be changed  :o !

a professional (engineer,ex-Phillips led-production department)told me that it is not the led by itself but the resistance inside  the lamp.

Hi magnetman, i can't make that experiment, because i don't want to ruin those bulbs.
Though i would imagine it's a little brighter and not as diffused.
Hi ianca, so are you saying the internal circuitry is not very reliable.
That is why mine are modified, more efficient and will last much longer, especially considering i'm not driving them to the max.
peace love light

I have come to a conclusion that no matter what light source you measure it will have to be placed under a frosted enclosure and the measurements taken off the top of the enclosure.  To many different  size led light bulbs not to mention the kelvin temperature they operate at. A large white plastic frosted hemisphere dome type of enclosure would be ideal as a standard.  Any ideas??
