Virtually indestructible LED emitter

Another quality element of this flashlight is its LED emitter. With the advancement in technology, most of today’s flashlights come with LED bulbs instead of incandescent ones. LED lamps are durable and robust than incandescent bulbs, which break on impact. Surefire E2D defender flashlight has a virtually indestructible LED emitter that delivers a secure and reliable light. The LED is regulated to offer high output and manage runtime.

The light beam produced by this flashlight doesn’t have a central dark spot like with some other flashlight brands.

Two output levels

I love that you have the option of choosing between high output and low output. This is vital, especially when you are out hunting, hiking, or camping. The high output level, which uses 600 lumens, cannot stay on for long but offers the brightest beam. On the other hand, the low output level, which uses 5 lumens is ideal for extended use of the flashlight.

Ergonomic tactical tail cap switch

Having a robust and powerful flashlight is not enough. You also need a flashlight that is easy to handle and use when there is an emergency. The Surefire E2D defender LED flashlight is ergonomically shaped to offer comfort and ease of use. The knurled design provides a firm grip that prevents the flashlight from shifting in your hand.

Besides, it has a tactical tail cap switch that you can operate with a lot of ease. For example, if you want to turn on maximum output in intense scenarios, the first click gives you a high output light beam. For an extended runtime or low output beam, click again, and you will get this output level. Note that you shouldn’t leave your flashlight on the high output level for long as it may overheat the torch.

Coated tempered window

One of the things that separate Surefire from other brands is its focused beam. Thanks to the TIR lens, that produces a centered beam with substantial reach and enough surround light for peripheral vision. As a result, you will see a distant person or object without struggling. The lens is also durable and protects the LED from damage.

Crenelated strike bezel

The Surefire E2D defender flashlight helps to serve your lighting needs, but it can also be used for defending yourself. The 600 lumens flashlight features robust construction that can withstand considerable impact. This means that you can use it to hit someone, and it won’t crash. Additionally, it has a strike bezel at the front of the flashlight that you can use to thrash an attacker. Of course, this is after disorienting the would-be attacker in the eyes with the bright high-output 600 lumens.

A unique feature of the Surefire E2D defender flashlight is its revolutionary pocket clip. This is because it makes keeping the torch when not in use convenient. The two-way pocket clip allows you to clip the flashlight from the bezel up or bezel down position. So, you don’t have to worry about which side the light is facing, as you can clip it with much ease.

Impact and water-resistant

As expected, an excellent tactical torch should resist both water and dust. Accompanied by an O-ring and gasket sealing, this unit will prevent any particles or water from entering. Both of these parts do a fantastic job of sealing the light and stopping the interior components from being damaged.

Apart from resistance to water and dust, the flashlight can also resist impact. Dropping a flashlight is something usual, but whether or not it remains intact or crashes depends on its durability. Therefore, you need to pick a flash lamp that can resist impact, more so if you intend to use it as a defensive weapon or for outdoor purposes.

The only challenge that you will face with the Surefire G2X flashlight is that they don’t disclose the level of impact-resistance or water-resistance.


Customers usually have joy when they buy from a brand that they can trust or even return a product if it arrives damaged. Surefire stands behind their products, and that’s one of the reasons they are a successful flashlight brand. You will get the support that you need if you received a product with an issue, or want their help.
