You could check whether what you're seeing a second line at ~490nm or the actual IR with scotopic vision. You just need a diffraction grating and a cheap camera (to avoid frying your eyes).
We've seen ~490nmn from ~980nm diodes before, so not all that surprising.

Whole thread may actually be worth a read for anyone that hasn't seen it already.
