ThruNite LED Penlight Flashlight, Ti4 V2 Max 252 Lumen Output, Ultimate Convenient AAA Battery-Powered(Not Included), Diminutive Slim Size Lightweight Little for Indoor/Outdoor/House/Workplace - NW

This is a great little light that's easy to carry all the time. My previous (and well-liked) EDC was a Streamlight Stylus Pro, but I wanted something with both dimmer and brighter settings and this fit the bill with three useful modes. In particular, I really like the sub-lumen mode. Other reviewers have commented that the lumen ratings are inaccurate, and I can't comment intelligently on that (so I'll comment less-than-intelligently). I don't worry about the accuracy of the lumen ratings; instead, I assess lights subjectively as "that's a useful setting" or "nah, not so much". The 3 levels on the Ti4 are thoroughly in the "useful" category. I would prefer not to have the strobe mode, but it's easy enough to avoid cycling to it and so I just ignore it.I LOVE the fact that it always comes on in the low sub-lumen mode. Lights that start on high make no sense to me, and so it's nice to have this one possess the same logic as I do. Now, she-who-resides-with-me-but-often-rolls-her-eyes-at-me would dispute the notion that I'm logical, but that's beyond the scope of this review. Suffice it to say, I like the mode sequence of the Ti4, which is all that matters here.Finally, a note on durability and waterproofness (which I hereby dub a word, even if Merriam-Webster does not). When, in the course of human events, the owner of a pair of jeans and a flashlight inadvertently (but quite understandably) leaves them together in the washing machine, one cleverly finds oneself conducting an experiment on how much abuse the flashlight can handle. I'm happy to report, the answer is at least one cycle. The light has a nicely weathered finish now, having lost some of the anodizing on the bezel and tail cap. Most importantly, though, it works fine. I think this light and I have a clear understanding of how this relationship is going to go: I'll be careless and neglectful, but I'll still expect it to be ready when I am...and it will be.It's not perfect; the switch doesn't feel as robust as I'd like, and battery life is pretty short on high (though you get a lot of output on 2 AAAs). If you can live with that, you get a lot of utility and durability for $25.

Excellent. Bought this as a medical penlight for night shifts in the ICU. The low mode is just enough to get a pupil reaction for neurological assessments, and doesn't hurt the patient's eyes. Medium is great for getting around dark rooms without waking patients up, checking equipment, examining the mouth, etc. High is perfect as a procedure light for catheter insertion, dressing changes/wound care, etc. My co-workers who borrow it are always impressed, both with performance and build quality. Most people use junk lights built out of cardboard and foil (seriously, I took one apart) for pennies and sold at a uniform outlet for $5. Don't skimp on the tools of your profession!!! You don't see serious craftsman using a $5 bargain-bin hammer, do you? Woodsman using a Wal-Mart brand axe? Nope.Color rendering is excellent, best of any light I own (though on par with the Thrunite T10). This is very important for a medical light. Cool white LEDs make any difference in skin tone look like a bruise; useless to aid in pt examination. Or, finding crap in the dark. Lol. I'm in-love with the "always start in low" feature. Too many times with my T10 (also bought as a work light) I have blinded myself, co-workers, and patients when it started in a brighter mode than expected. I found myself always cycling to low before turning it off. Not a huge deal, but inconvenient. T10 is now my EDC light, Ti4 WAS my work light, but I lost it. Went to buy a replacement, not available on Amazon anymore in NW, which is a non-negotiatiable. C'est la vie. Maybe Thrunite will "see the light" and sell more of the CW torches :)

Review for the ThruNite neutral white penlight black aluminum body.Arrived on time and in good shape. It came in a labeled box with instructions and 2 spare O rings. Fit and finish seem fine. Threads were greased a little bit.I like it. The switch is a reverse click that is fairly stiff – which is fine for what it’s used for. It’s unlikely to be pressed by accident.The three brightness settings are just about right. Firefly is good for bum-bulling about the house with dark adapted eyes. Medium is good for really seeing indoors both at dark and peering under stuff during daylight. Bright is well, bright. Amazing how much light they can get out of 2 AAAs.I like the UI. Always defaulting to firefly is great. No need to blind the world when turning it on at night. If turned off for less than 10 seconds it will come back on to last setting. I haven’t measured, but I assume there is no parasitic drain because of UI.This thing is quite a bit heavier than a $10 hardware store penlight. I’ve dropped it a few times and it’s still working fine.The neutral white color works better for me when used outside. The $10 hardware store penlight looked OK till I got this one. It looks blue next to the Thrunite.I’m running it on 2 AAA Eneloops. Works just fine so far. I use it almost every day - err night.The center spot is fairly tight. I wish this was more of a flood. My idea of a correct beam is something that will light up a book page when using it to read at night. This one is too tight for that. A layer of frosted magic tape across the lens really helps this. But the tape makes the firefly mode a little too dim for good use as a light to move around with.It has a strobe mode. I guess if I tip a rack of servers over on me I can signal for help. Don’t really see a need for this mode in a penlight.I wish is came in something other than black. I mean, what’s more important – making sure a kitten waiting in ambush can’t see a reflective gleam off the light body or my being able to see the thing when I drop it in a dark corner? Make it in bright day-glow yellow. Get over this ninja – tactical stuff.Instead of the strobe how about a mode that shines at a selected brightness than shuts off automatically after 5 minutes. Set it some place – get tucked into bed or a sleeping bag and not have to reach out and fuss with the light. I’ve got an old flashlight that does this and I find it really useful.I have not had the Streamlight, Fenix, Nitecore, or 4Sevens version to compare to. I really like this one because of the great UI. Make it with more flood, in yellow, and auto shut off - then it’s six stars.
