Best carry light I've found
Posted by Fran - Wisconsin on 15th Dec 2018
I really like this flashlight! At 1/2" x 5 ¼” I can put this flashlight in any pocket that I have, with or without the clip, and not even know it’s there. But, it's big enough that I can easily find it in any pocket. I always have it with me and I use it more than I thought I would. The non-adjustable beam is great for a flashlight this size. There are distinct differences in the three brightness settings. The highest setting is brighter than I thought it would be.
At first I wasn’t sure that I would like the way it operates. It only remembers your last setting for ten seconds. So basically it turns on to the "firefly" mode every time. Then, you have to either partially press the button, or, a quick off/on to increase the brightness. But, that is quickly learned so it is not a problem. Also, I thought the “firefly” mode was too dim to be useful. I was wrong. You will use it more than you think. It’s got strobe also.
To me, you get a lot of flashlight for 20 bucks. More important, it is so easy to have it on you at all times no matter what you’re wearing.

Awesome light for edc.
Best bedside light
Posted by jaap on 31st Aug 2018
The best of feature this Thrunite Ti4 flashlight is that it has no memory of the last used brightness. It will always start in firefly mode. That's great, because it doesn't disturb anyone or spoil my night vision when ever I turn it on. It's always on my bed stand. It runs fine on just two eneloop AAA batteries. Still it is able to produce at lot of light when needed.
VERY BRIGHT FOR PEN LIGHT
Posted by CM on 24th Jan 2018
I would pay double the price if I could program the settings order to bright, medium, and firefly.
Very Good with one concern
Posted by Greg on 22nd Jan 2018
Pen light is small sleek and works well with 2 AA. Fits pocket well with clip. Light seems to have three settings, firefly, medium and bright. All are perfect for such a small light. Only concern that the on/off and brightness control at the rear of the light, like a retractable pen wiggles and once on is hard to manipulate the brightness control. Other than that is is a good light.
My great telling!

I love this light.. Multiple settings, perfect size.. I like that it has memory for last light setting used though memory only lasts 10 seconds. After that it defaults to the firefly setting. you can just 1/2 press the knob lightly and it will cycle the settings easily. I also own another product from them that memory does stay at last used power when you turn it back on possibly will be added one day... Hint, hint...
This is a great lightweight powerfull light

We use this light all the time very compact and very bright, we will buy this item again, thanks.
Perfect For First-Aid Kit
Posted by Thatnub on 14th Sep 2016
After updating my first-aid kit I realized that I didn’t have a flashlight in there. I looked through all of my flashlights to find the appropriate one but, they all had that tacti-cool skin. If I was going to be using this flashlight where blood and debris could get on it, I wanted it to be easy to clean off. Enter this ThruNite Ti4. With its smooth aircraft grade aluminum skin, it would be easy to wipe off and keep clean. The low setting of 24 lumens is perfect for looking in cuts, ears, noses, mouths and even eyeballs without blinding your patient. On that setting I could leave the light on for 12 hours before the two AAA batteries wore down. This light will last a long time in my first-aid kit before I have to recharge the batteries I put in.
Excellent Pen Light

I own quite a few lights and this one is an excellent addition.Very bright. I wish it had memory and momentary on off but beside that excellent pen light.
My Current Favorite EDC Flashlight
Posted by Robert on 16th Jan 2016
The ThruNite Ti 4 Penlight Cool White is now my favorite EDC flashlight. It is the brightest AAA penlight I have found so far, and the quality is excellent. It is small and elegant and fits in a business shirt pocket easily or a pants pocket without being too bulky. The Firefly setting is perfect for use to examine a menu in a dark restaurant setting without disturbing other restaurant guests, and you can quickly switch to the brighter settings with a tap or two as necessary. My only criticism is that I wish it was quicker to get to the stobe setting so it was the 4th selection instead of 7th.

I bought these pen lights as Christmas gifts for my family members. I opened mine early and wow was I impressed with how bright this little pen is. I love the 3 brightness levels.
