You need enough light to positively identify friend or foe and no more.
I’m with you on the TLR-1 HL. Current lights are 1,000 lumens. The earlier models were 800. Both are fantastic in function, durable and aren’t too expensive. My old agency had a few hundred we used with minimal problems.TLR1-HL
Blinding to whatever your covering with it and lights up light daylight immediately
That is what is on my nightstand pistol .
I would agree with you on this for sure. Your statement of how you apply the light is 100% true, splashing it into the room and flood/gill giving the most efficiency out of the time the light is on.You can get away with just about any type of light in a house, even a XC1. I even think a XC1 could arguably have an advantage inside a house, where it is generally inadequate elsewhere.
I think the key to success with a wml is to understand the balance of flood & fill vs spot that it has, at what brightness, and what technique to apply with it. One of things I find missing in the majority of low light training and discussion is the concept of considering what you "buy" with each activation "cost". This is true indoors and outdoors, and indoors the more spot a light has, the higher the "cost" of each of your "buys".
if the only place you want a wml is inside the house, then something like a x300 is likely over kill. A single cell set up like a tlr7 or something from inforce would be good.
