400 Here's the theory. You can see that the streamer has 355 light, but he also has a beginner ghost shell, which has a value of 5. The light level in destiny is the average of all the gear, and if we assume that he's wearing max or at least near max gear, then we can use this equation: (X=max or near max gear) (x+x+x+x+x+x+x+x+5) / 9 = 355 If we plug in 400 for the gear, (x) we can see that it just tips over 356, which means that he is probably wearing some lover level gear like 399 or 398, along with some 400. However, this math shows that the max light level (assuming that he is wearing near-max/max light gear) for destiny rise of iron is going to be 400. Thank you all for your time and remember this is all speculation, but in any case, have a great day.
