Well I guess its important to note, you saw him opening light but have you seen him 4bet light?  With that being said we just dropped almost 1/4 of our stack in preflop. He has to shove or fold here and I think your call is fine. We are probably ahead of most of his range, which I would give him exactly what you said which isnt super loose or super tight. If we stove that range against JJ is almost exactly 50/50. A double up is huge for us and since we should almost always raise here and have so much in the pot when he shoves Im calling 100%…….you just got coolered.
