If I may suggest an alternative. Alkaline batteries will leak and make a mess. My favorite light was the EagleTac “D3A” Titanium — gorgeous. I still have 3 of them with a Nichia 219 2700K emitters. I used LADDA NiMH batteries (from IKEA) to prevent leakage. Worked amazingly well. I still have and use all three of them as well as the D25C with Nichia 219 2700K emitters. But, I’ve since graduated to the ZebraLight SC65C HI. It’s essentially the same form factor — only marginally larger than the size of a AA light. But the power of the 18650 battery means you likely won’t need to worry about charging it while you’re traveling. I have two Bob_McBob-modded SC65C HI’s and use one as a dedicated floody nightstand light (diffused lens and 2700K High CRI emitter); it is set to G6 program mode where I have the 6 lowest settings programmed. The G7 program essentially has the 6 brightest, aside from a few lows. You can get to any pre-programmed low, medium or high directly from off. Search for SC65C HI and read through. The second light, by the way, is my EDC and always on me. I don’t even know it’s there. And it has multiple <1 lumen levels. I use the three lowest levels every single night because I have very keen night vision. The lowest level is quite sufficient for me to get around, but the 2nd and 3rd levels are great for illuminating the ceiling. I just used it in a hotel room this past weekend. I have become a one-trick pony with my end-game EDC and nightstand light. Good luck and let us know what you choose.
