The Streamlight 78121 Stinger 2020 is a powerful rechargeable flashlight designed for professional and outdoor use. It delivers up to 2,000 lumens on its highest setting, lighting up areas as far as 315 meters, which is excellent for seeing long distances in the dark. You can also choose medium, low, or strobe modes, with runtimes ranging from 2 hours on high to an impressive 24 hours on low, making it versatile for different lighting needs without frequent recharging. The flashlight uses rechargeable lithium-ion batteries and comes with a convenient AC/DC charger, so keeping it powered is straightforward.

Its aluminum body is tough and built to last, with water resistance that allows submersion up to 1 meter and impact resistance from drops up to 2 meters, suitable for rugged environments. The grip is textured and ergonomic, helping it feel secure in your hand during use. At about 0.8 pounds and 7.7 inches long, it’s compact enough to carry easily but still has a substantial feel.

A minor drawback is that while it’s waterproof for brief drops or rain, it’s not designed for underwater use, so it’s best to avoid heavy water exposure. Also, at nearly $100 or more depending on the retailer, it’s an investment best suited for users who need a reliable, bright, and durable light—such as law enforcement, campers, or safety workers—rather than casual users who might not need the extra features. This flashlight offers strong brightness, solid battery life, and rugged design, making it a dependable choice for demanding tasks.

The 2000 lumens output lights up large areas like daylight, delivering truly impressive brightness.
Durability
The build quality feels heavy-duty and solid, far from cheap plastic, ensuring durability in tough conditions.

The Streamlight 89009 ProTac 2.0 is a powerful and versatile tactical flashlight designed to mount on firearms using Picatinny rails. Its standout feature is the very bright LED output, delivering up to 2,000 lumens with a beam that can reach 266 meters, which is excellent for clear visibility in dark or tactical situations. If you prefer longer use, the flashlight offers a low mode at 250 lumens that can last up to 11 hours, plus a strobe mode for signaling or disorienting. The included rechargeable lithium-ion battery uses USB-C charging and provides decent runtime, though a full recharge takes about 6 hours.

Constructed from durable aluminum, this flashlight is impact resistant and rated IP67, meaning it’s dust-tight and waterproof for up to 1 meter for 30 minutes, making it reliable in tough outdoor or professional environments. Size-wise, it’s compact and fairly lightweight at just over half a pound, which helps keep your weapon balanced. The remote pressure switch with latching button adds convenience for quick and easy activation. On the downside, the 2.5 hours runtime at maximum brightness might require carrying extra batteries or charging opportunities during extended use. Also, it is specifically designed for weapon mounting, so it’s less suitable if you need a handheld flashlight for general use.

This flashlight is especially beneficial for professionals, law enforcement, or serious outdoor enthusiasts who need a high-performance, rugged weapon light that combines brightness, durability, and practical controls.

Buying Guide for the Best Streamlight Flashlight

Choosing the right Streamlight flashlight involves understanding your specific needs and how different features can meet those needs. Streamlight offers a variety of flashlights designed for different purposes, from everyday carry to tactical use. To make an informed decision, you should consider several key specifications that will determine the flashlight's performance and suitability for your intended use.
LumensLumens measure the total amount of visible light emitted by the flashlight. This spec is important because it determines how bright the flashlight will be. Flashlights with lower lumens (around 100-300) are suitable for general use, such as finding items in the dark or walking at night. Medium lumens (300-1000) are good for outdoor activities like camping or hiking. High lumens (1000+) are ideal for tactical use, search and rescue, or situations where you need a powerful beam. Choose the lumen level based on how bright you need the light to be for your specific tasks.
Beam DistanceBeam distance indicates how far the light will project. This is important for activities where you need to see far ahead, such as hiking in the dark or searching for something at a distance. Short beam distances (up to 100 meters) are adequate for close-up tasks and indoor use. Medium distances (100-300 meters) are suitable for outdoor activities and general use. Long beam distances (300+ meters) are necessary for search and rescue operations or tactical situations. Consider how far you need to see and choose a flashlight with an appropriate beam distance.
Battery TypeThe type of battery a flashlight uses affects its runtime, convenience, and cost. Flashlights can use disposable batteries (like AA or CR123A) or rechargeable batteries (like lithium-ion). Disposable batteries are easy to replace and find, making them convenient for occasional use. Rechargeable batteries are more cost-effective in the long run and environmentally friendly, ideal for frequent use. Consider how often you will use the flashlight and whether you prefer the convenience of disposable batteries or the long-term savings of rechargeable ones.
RuntimeRuntime refers to how long the flashlight can operate on a single set of batteries. This is crucial for activities where you need prolonged use, such as camping trips or emergency situations. Short runtimes (up to 2 hours) are sufficient for occasional, brief use. Medium runtimes (2-10 hours) are good for regular use and outdoor activities. Long runtimes (10+ hours) are essential for extended use without frequent recharging or battery changes. Think about how long you need the flashlight to last and choose one with a suitable runtime.
DurabilityDurability indicates how well the flashlight can withstand rough handling, impacts, and harsh conditions. This is important if you plan to use the flashlight in demanding environments. Look for features like impact resistance and water resistance. Flashlights with basic durability are fine for everyday use. Medium durability is suitable for outdoor activities and occasional rough handling. High durability is necessary for tactical use, professional work, or extreme conditions. Assess the environments in which you will use the flashlight and choose one with the appropriate level of durability.
Size and WeightThe size and weight of a flashlight affect its portability and ease of use. Smaller, lighter flashlights are easier to carry and handle, making them ideal for everyday carry or travel. Medium-sized flashlights offer a balance between portability and performance, suitable for general use and outdoor activities. Larger, heavier flashlights may provide more power and features but can be cumbersome to carry, best for tactical use or situations where you need a powerful light source. Consider how you will carry and use the flashlight and choose a size and weight that fits your needs.
