Here is a measely 160 lumen light boasting 12000 candela.
Gen 2 Streamlight Strions and TL2 LED's had virtually the same beam.
Note the wall to the right.
As you can see, there is plenty of spill to see by.
The higher candela number means it is more likely to drill a hole in fog or smoke better than a lower candela.
The lower candela is best for close up work without blinding yourself.
Both will provide plenty of spill.
