Hello everybody! You might think the 100 lm. setting for the white light is too low for practical use, but no, it is perfect for indoor use in your home! The idea is to be able to identify any intruder/family member, before you put your finger on the trigger. The 100 lm. light does this especially well without blinding yourself, (from light bouncing off your walls or stuff). The battery charging feature makes it practical to practice with this tactical light/laser and still always have a fully charged battery for when/if you do actually need to use it in a defensive situation; or to chew out a family member who is trying to sneak in after curfew. Of course, practice switching over to 800lm, from time to time to keep in practice for that too; really scares the hell out of a kid breaking the house rules too!
