Curious as I am - may I asked how you come up with theses numbers?
Second, 150 mA is about a 1/10 of the current named in the data sheet (1120 mA). I couldn't imagine that the LED will start shining at all at... interesting.
This is current per diode.
Just look into Samsung calculator on their site and you can play with numbers.
