Re: Another questionin question.
Question, since I'm new to flashlights and all this stuff. Is the nitecore p30i able to let me switch modes without clicking the button each time? Like can I go from turbo mode to medium mode without having to go through each mode first? I don't know how to describe the term exactly but you know what I mean.
First, let me apologize for listing the L18, as I meant the newer L19 from Acebeam. I edited my original post.
The P30i has an on/off button at the back, and a mode switch on the side. It has mode memory, so it will come on whatever mode you were last using. If you turn the flashlight on and off over and over, it doesn't change the brightness setting, e.g. if you are signaling. At any brightness level, when on, if you hold the mode button down for a second it will switch to Turbo. From there, hit the mode button again and it returns to the previous brightness. It sounds complicated but it's pretty useful and intuitive. I have a similar Turbo "hold" for my i4000R and it works well, even though I have to wait <1 second to get that Turbo going... although the i4000R's Turbo only stays on as long as I hold the mode button.
The MH40GTR is the older design, where the on/off button is on the tailcap, a fully tightened head is always the highest setting, and a loosened head allows you to cycle through the other brightness settings with the on/off tailcap button. It has mode memory with the loosened head, but it takes a few seconds on off to remember the mode.
If the Acebeam's L19 I mentioned is anything like my x10 and L35 UI, the tailcap button is always on Turbo, and the side switch both turns the light on with mode memory, or long press to start in moonlight and cycle up. When on, whatever brightness setting is being used can be overriden by hitting the tailcap button for Turbo. I think the K40 has an on/of button on the tail cap and a ring for adjusting modes near the head.
Personally, unless you really want to be able to charge the flashlight without taking the battery out, I might suggest the Acebeam L19 if you want a single battery dedicated thrower. The L19 has no charging port on the flashlight, but you can use a battery that has a charging port on it.
I should also mention, that these lights have minimal spill, so if you want to use them as an all around light, you will be staring at a 4 inch glaring spot on the ground at close range.
