The Dinotte model numbers don't indicate the lumens, at least not universally. The 140 requires external batteries; the 300 is self contained and has more mounting options. I've read that the 300R claimed lumens is 150. I've read that the 140 is actually brighter, or perhaps it only appears so because the light is coming from a smaller point; the 300R is spread through a lens.
Check that, from Dinotte
Light Output Comparison
The 300R is brighter than the 140R
The 300R is not quite as bright as the 400R
