The 1 watt number is impressive (tint tbd), the 2 watt number is not nearly the 373 lumens that I get at 2 watts when I run my xpl v6 4200kelvin, using computer finned heat sink (plus one to hold the aluminum reflector), 92% efficient buck driver from two 18650.
I am trying to get my head around the csp led format. Apparently not so good at heat dissipation; probably unidirectional emission; large die so no focum; cheaper to produce, but maybe not, http://www.ledsmagazine.com/article...artments/commentary/to-csp-or-not-to-csp.html.
But the csp implications (on fl community or over 100 watt flood/worklights), I cannot grasp without a good youtube video. ... I would have never grasp the led on pcb without examining the boards and led in person, maybe through video-probably not ever via diagram, much less via description.
