yan yung degree ng ilaw nung LED at pattern ng light output ng mga LED
middle / center being the brightest
oo yan yun bale pag walang lens hindi aabot ng CR yung liwanag kasi 160 deg yung distribution ng light, where as 30 deg pag may collimator/lens/holder lalayo yung "bato" nung light. pag madilim na kuha ulit ako,

Yes, that is possible but the efficiency is great concerned for this wide range input
And the components selection will be a challenge

I have a 220Vac driver I'm not yet sure about the output I'll try to test it later. The output voltage is around 10V.
