SnapLED powerd straight from 18650 or CR123A 3.7Volt battery?

So I don't know if you know about the red-orange SnapLED, but here is the information on it. http://www.philipslumileds.com/products/snapled#datasheets

I want to power one of these with a 3.7 volt battery like a 18650 or CR123A. (or the 3Volt options)

What is the most simple circuit I can use that will provide long life for my led?

This led confuses me because it runs at 150ma (which is right on the boarder of High power leds)
You have to treat High power leds usually more carefully than with just resistors.

Will just resistors be sufficient for a 150ma led?

This is probably all you need.
