Hey guys, I found the spec sheets for both of these LEDs, but I'm having a hard time understanding them.
XM-L: http://www.cree.com/~/media/Files/Cree/LED%20Components%20and%20Modules/XLamp/Data%20and%20Binning/XLampXML.pdf
Nichia 219: http://www.nichia.co.jp/specification/en/product/led/NVSL219A-H1-E.pdf
It says the 90 CRI XM-L S6 @ 700ma will do 182 lumens.
The Nichia 219 92 CRI B10 @ 350ma will do 100-110 lumens.
Would this be simple extrapolation or am I missing something like voltage differences? If not then the Nichia would do ~220 lumens at 700ma, which would mean it's brighter.
