Streamlight 89000 ProTac 2.0 2000-Lumen Rechargeable Tactical Flashlight with USB C Cable, and Holster, Box, Black

Great light. Easy to charge. At bit bulky if used as a weapon light, but amazing value for the brightness compared to other weapon lights,

It's friggin bright! I read in another review that someone said that it's claim of 2000 lumens was off because it was the same as their 500 lumen smaller light. I don't know if they have a defective one or are mistaken but I have two Streamlight tac lights, one is a 500 and non-rechargeable and the other is this. I'm telling you it's damn well seems like it is 4 times as bright. The only downside and this is a Streamlight issue but all decent rechargeable lights issue is that it takes a while to recharge.

Arrived today in excellent condition and works great 100% TAC LIGHT ! well made and very bright after being fully charged ... Would highly recommend this unit for LEO'S and Home defense needs..

Great light. Bright and durable. Another Streetlight that is great. I would purchase again.

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.

As advertised. Streamlight is the best. Super bright at 2000 lumens.

So far, this flashlight is working just fine. I wish the battery had been equipped with a more accurate readout of its remaining lifetime such as 1 light for 25%, 2 lights for 50%, 3 lights for 75% remaining 'juice', etc.
