I'm totally new to this so please bear with me. This will be my next light platform and doing my due diligence. To me, the benefit of a dropin versus a fixed light engine is the ability to swap the emitter using the same host, correct? This is ideal for me, because, I don't really want to buy a lot of flashlights for different purposes (well, a lot is relative term I guess). I'd like to buy a nice host, then I can buy different dropins with different tints, outputs, flood versus throw, etc, etc. Am I correct in saying this?? Please tell me. Also, do you guys who have these, frequently change your drop-in? or does it become a pain, so the drop-on/host essentially becomes a fixed light? Looking forward to your collective thoughts, thanks!
