This seems vastly overspecced.. Reports suggest the real candela is around 26kcd. This is also in line of what you get when you dedome.
The factory version has dome on. Vinh dedomes them and picks the best tint emitters and uses those, so it's a process to get good ones. He also changes the board that the emitters are on, to rotate them to create a better shaped beam. This results in more throw, better tint, and a better beam patternI am new to all this. Can someone explain why the D4VN XPG2 version costs so much more than his other modded D4Vn? What is so special about that emitter?
I have both the stock Nichia 219c and Vinh's XPG2 PDT mod. I've measured both on my cell phone lights meter, so can give only relative data.
The D4vn XPG2 measures exactly double the D4 Nichia 219c, center of beam at 17 meters.
The Nichia is noticeably brighter in ceiling bounce indoors, which makes sense.
What light and how is it worse?I see what you mean now. But I don't agree with you that his numbers are conservative.
I have one of his modded lights that according to his numbers should be much better than its stock form. However, it's in fact much worse.
I know that my meter shows true numbers. Because almost all my light is within 5% of the manufacturers specs.
