I strongly recommend the Streamlight Protac 2L-X model. In fact, I bought a 2nd one because I find it ideal as a true tactical light, and if anything happens to my first one; I don't have to go hunting for a replacement for it many years later after the light has been either discontinued or "improved" into possibly something far less useful.
Check it out on Streamlight's official website. I've never had an issue in which a lower setting came on, when I wanted the highest. But since the light is programmable, you can literally set the modes to the combination that works best for you, or the one you prefer. No need to cycle through modes that are useless to you, just to get to the one you want. Heck, you can even set it up to have one mode. Full-on brightness if you want. Output is closer to 500 lumens than 80. But if you prefer 80, you can again program the light. Once done. Leave it alone and it functions how you want it to.
Good pocket-clip. Not fantastic. Just good. But I've never had an issue with the light falling out of my pants pocket. Two battery options, 18650 rechargeable or 2xCR123 primaries. If you're not very knowledgeable on the types of serious issues that 18650s and similar rechargeables can cause, I'd stick with CR123s for this light. If you are knowledgeable, Streamlight has USB rechargeable 18650s that you can use in this light. Making it even more ideal.
Streamlight doesn't get a lot of attention on CPF. But only because they make incredibly reliable lights that just work. (Okay, they have literally a couple of models that should be avoided at all costs. But none of those are part of the Protac line.) Streamlight is like the Toyota of lights. Very reliable, very dependable, but nothing that folks openly brag about.
You can get the Streamlight Protac 2L-X online at a variety shops for right around $50 + shipping.
