Some people define LED as "light emitting device," so anything that emits photons could technically be considered an LED XD (including all lasers)
Bit late but I just confirmed its glass.656 - this was the number that made me wonder in the first thread about this chip. If by this wavelength was meant like in Osram PLPM 450, then this thing should be red. But deep red and not as bright to human eye as multi-die 637nm package from Necsel in the link above.
Another bad thing about red lasers - they do not like temperatures above rt.
So I would not power all rows without ice-cooled set up similar to one which I made for testing NUBM31 and Osram chip in my earlier topics.
EDIT: is the lens made of glass or plastic here? Regarding the cheap price of chips you got it could be plastic. Unlike for blue lasers plastic (acrylic) lenses can be OK for reds.
