I place the green lense cover on my Strion, it works great. The lense let me use the light with 2 options: to read or look for items with out messing up my night vision in the car; and I can flip the lense out and use the light for it intended purpose for searching of an area where a bright white intense light is needed.
Pros: Great tight fit around lense
Cons: After placing the flip lense on your light, Your light with the flip lense might not fit in the duty belt light pouch if it has a flap cover with a snap.
