5 of 5 Excellent very versatile light February 17, 2022
Reviewer: Anonymous Person from Dale City, VA United States  
The versatility of this light is awesome. The ease to switch from flood to throw is its main asset. The only thing I would change is to increase the lumens for the throw mode to 2000. The 11,000 lumens in flood mode is awesome. If looking for versatility along with high lumens, you can’t go wrong with the LR40R. This is definitely a keeper, and I might add, this is my second one, I like it so much.
