You have a lot of options if money is not an issue.
Novatac 120P - I'm planning on buying this in a couple of weeks. I looks like it's built like a tank. Take one CR123a or RCR123a battery and programmable brigthness from 0.3 lumens to 120 lumens. The runtime is a tad low (around 30-45 minutes) for 120 lumens, but I've already have more than enough bright lights. I'll probably set my high at around 60 lumens (I survived perfectly fine with my old 40 lumens Inova T2). I've been reading up on it on this forum ... you usually find two extremes ... those who love this light and those who would bash it. Even though it's expensive, I'm going to try it out to see how I like it. Worst case scenario I will return it or sell it on CPFM. Also, some members recommend the HDS System RA Twisty. I'm not a big twisty guy, so this is not really for me.
Lumapower Incendio - super small light that runs on one CR123a or RCR123a battery. You get 130 lumens for 130 minutes / 40 lumens for 9 hours / 7 lumens for 35 hours. I like the simplicity, but wish that the low could be lower than 7 lumens.
Nitecore Defender Infinity - small, lightweight, runs on one AA equivalent (akaline, nimh, li-ion) battery. The max is around 180 lumens and low could get pretty low. The "tactical" mode runs on max (or strobe) and the user-defined mode is the programmable by the user. I've been EDCing this light since I got it (last week). There's some minor UI issue for me, but I still like it.
Fenix L0d, L1d, L2d, P2d, P3d - they're all good. You have the option of 1 x AAA, 1 x AA, 2 x AA, 1 x CR123a, and 2 x CR123a. I have the L0d on my keychain all the time, and alternate the L1d with my NDI and Incendio. My two main nitpicks are (1) that they lack knurling, so the smaller models (L1d, P2d) can get slippery, and (2) they don't support Li-Ion batteries. I have other minor nitpicks as well, but that applies to all flashlights in general. I guess you can't have it all :shrug:
Zebralight H30 - I don't have this one, but I've been eyeing on it as well. It doesn't have much throw, but it's a great flood light. It'll probably get one for close-up work.
Anyway, good luck in your search.
