According to one reviewer the XPG is only brighter on Low & Turbo, and 219c is only 474 less (on turbo)
And 219c is brighter on Medium, Medium1 and high…
But it looks like he’s just going off the factory specs for his conclusion, so not the actual lumens comparison you were looking for.
“The Nichia 219 LED’s produce a whiter neutral white output and only sacrifice a small amount of output in doing so. The human eye can’t tell the difference between the 12000 lumens that this light produces with the XPG3 LED and the 11526 lumens it produces with the 219C LED’s. What a little strange is On low and turbo the XPG3 LED’s produce more lumens but on Medium, Medium1 and high the 219C LED’s produce more lumens. Throw distance is the same”
From this review: [Review]Astrolux MF01 4x18650 18xNichia 219C
I think for this light personally I would try the 219c, because I don’t really like CW tint.
Can someone say what the (actual) turbo output is for 219c? I read it somewhere here but can’t remember where.
