Streamlight89000 ProTac 2.0 2000-Lumen 17300 Candela Rechargeable Tactical LED Flashlight with USB C Cable, and Holster, Box, Black

Awesome flashlight!! Prior experience with Streamlight. This one is bright!! A little bigger than my older EDC flashlight, but being bright and rechargeable, I can overlook the size. Still fits in my pocket. Why did you pick this product vs others?:Prior experience with Streamlight and very durable.

Design is great. Easy, water resistant access to the battery. The 10 tap button function is interesting and does it's job. Super bright and matches it's counterpart that is mounted. Includes compact carry case as well to add to your belt. I've had it for a month and the battery is still running a great charge. Well worth.

Quality is great and man is it bright!! The unit is compact enough to be pocketable with most pants, but not so small as to be hard to handle, perfect size. The pocket clip is super convenient, love this feature. In fact it is so bright, than I cant use it in some close-up cases, the light will reflect back and temporarily blind you. I really like that it is USB chargeable, that is super convenient over a dedicated cradle charger.

I don't write many reviews, but I've been using this flashlight for 3 weeks now and this thing is awesome. I've used it so far for dog walks and a short power outage. Admittedly, it's probably overkill for my use cases, but I never know when I'll NEED something like this...so I'm glad I have it. The low brightness settting is just bright enough for my use. Medium is practically perfect - cars no longer blow through stop signs when I'm out for a walk. And the high setting will light up my neighborhood sidewalks for almost an entire block. The build just feels solid and well-made. Beam cannot be focused, but that isn't needed for a flashlight this bright. The battery is fantastic too. I used it for about 5 hours total in various brightness settings before a recharge was needed. It probably wasn't necessary, but I bought a spare SL-B50 just in case and because it was so reasonably priced. I highly recommend this flashlight.

2000 lumens output is intense. USB-C rechargeable is convenient. Durable build. Holster included. Great for pro or serious use.

I initially picked this light to try the somewhat controversial sliding port cover. The port cover is held in place by two possibly silicone O-rings (one is under the ring). Although useful, somehow have found this cover to slide out of place in use. I oiled the O-rings with PTFE oil to protect them from wear, and to promote water resistance. I found that if it sits for several minutes it settles and becomes harder to pull back accidentally, though some grip styles may inadvertently pull it back regardless. These orange-red o-rings may be silicone, so avoid silicone oil or grease.I noticed the tumbled aluminum can feel a bit slippery at times, but I haven’t dropped it yet as the shape helps it stay in hand. It feels heavy, and you can feel the presence in a pocket. The shape didn’t create large pressure spots on my leg even with my tight fitting pants like some lights have, but it was definitely noticeable, still not exactly a pocket light due to size and weight.The coating on the light is Type II Hard anodized, which is adequate, but falls short of some brands that have used type III Hard anodizing. In experience this translates to more wear. Scuffs from cement under a car, or riding next to gear like a knife will more easily show, yet can chip less due to being thinner and slightly more flexible.The tail cap is thick, which should handle drops well, and I appreciate the three protruding scallops on the back, as I broke a switch from a small floor on linoleum in the past. This will protect it from drops, but could hinder quick button presses.The light can tail stand very well, in fact I was able to charge it with a thick cord while it was tail standing.The grippy silicone boot collects pocket lint and dirt but should be rather wear resistant. When pressure is applied to the switch you can use momentary mode for quick use. When depressed fully the click is heavy feeling and audible from across the room, but is muffled enough to not be an issue in most uses.I tested the light in a foot of water for an hour and it seemed fine, but before I did this I lubed the dry orings.With the sliding cover I would hesitate to bring this underwater without care. For example, I wouldn’t let my child play with it in a pool like I have some lights.I cannot say how durable this light is, but it seems quite thick. I wouldn’t hesitate to buy this for a mechanic for every day use.The battery is the proprietary SL-B50, which can be purchased on Amazon as a spare. I did buy the spare because it can take 5.5 to 6 hours to charge. Slower charging can aid in overall life and safety of the battery, but can be a pain when you need your light.The best part is you can charge the drained battery in a pack with a portable battery bank. At the most it pulled just under 5 watts when I charged it, perfect for plugging into a computer or even slow charging car USB ports.Streamlight doesn’t disclose what cell they use under the wrapper but they have a history of using quality cells such as Panasonic, Sanyo (owned by Panasonic), and Samsung.When inserting the battery you should rotate it so it fall into place if it is not mostly flush with the lip of the battery tube. Once In place, it will come into contact with two spring loaded bullet caps at the bottom (pictured). Spring loaded front and back is ideal to prevent battery damage from drops. I have personally crushed the end of a battery from a hard drop on concrete so it’s appreciated.The light can be partly disassembled which will show an aluminum reflector and white plastic (not pictured) to help center the led. You can remove the plastic piece to show a MCPCB board which is standard aluminum, with standard thermal paste (not thermal glue) meaning that with a bit of googling one could swap out the led and board with a better led.The led itself seems like a clone of the Cree XHP50/XHP50.2 or the luminous SST-70. I believe they were going for lumen per dollar vs nice tint. The beam on a white wall has noticeable tint shift, meaning the center is a cold blue white and turns to greenish hue and to a white. Not exactly ideal. In real world use this didn’t matter too much, but when I compared it to a light with good tint and high color rendering (being able to show colors accurately) it was noticeable, but otherwise won’t hinder every day use much I’m in being honest. It makes light.The ten tap is very useful. I set it in low, medium, High mode to prevent accidental melted holes in my pack. Though with a small twist of the tail cap you can lock out the light, meaning it won’t turn on even if the button is depressed. This is a good safety feature for storage as it can get hot, as all powerful lights do, but this can slow activation of the light.Would I purchase again? Yes, but it has room for improvement.Specs:Light Output and Run Times:• High: 2,000 lumens; 262-meter beam distance; 2.5-hour run time.• Medium: 570 lumens; 142-meter beam distance; 4.5-hour run time.• Low: 100 lumens; 60-meter beam distance; 25-hour run time.• Strobe: Runs for 4 hours and 25 minutes.Battery:• Powered by one (1) Streamlight SL-B50® protected Li-Ion USB-rechargeable battery pack (included).• The SL-B50 battery pack features an integrated USB-C charging port, allowing charging inside or outside the flashlight.(Takes up to 6 hours to charge)Dimensions and Weight:• Length: 6.10 inches (15.5 cm). • Weight: 8.25 ounces (234 g) with the battery pack.Construction and Durability:• Made from 6000 series machined aircraft aluminum with a Type II MIL-Spec anodized finish.• Features an anti-roll head to prevent the light from rolling away when placed on a flat surface.• IP67-rated: dust-tight and waterproof to 1 meter for 30 minutes.• Tested for 2-meter impact resistance.Additional Features:• Equipped with Streamlight’s TEN-TAP® programming, offering three user-selectable programs:1.

I absolutely love this flashlight. I work night shift in oil and gas. This thing lights up the night. Super bright. Good lasting battery. Dropped it several times at work from pretty decent heights checking tanks and even dropped it into water a couple times. Still works like a charm. Definitely worth the money. Streamlight lights are never a bad buy!!

Super bright, fits on vest, awesome battery life, great buy for officers, button easy to press, design of light is nice
