Help identifying streamlight model

[cgseanp1]

I have a streamlight strion LED HL flashlight. The s/n is 087576 1114. It only seems to have 2 modes, high and strobe.. I see there are a bunch of different strions online with different model #s, but I can't find this and they also all seem to have 3 modes plus strobe.. can anyone help identifying what model mine is?
I also have the 74102 charger with it.. Thanks

How are you trying to cycle through the modes? Most Streamlight's I have used cycle by holding the switch down to cycle high med low, and double click to go to strobe.
