It's true, good things do come in small packages. The E1b "Backup" by Surefire is the perfect example of this.
This light is perhaps my favorite light of all of them, and trust me.. I own a very varied collection of flashlights. These are some awesome features of the "Backup:"
1. Very small. Fits in the palm of your hand. Rides in your pant pocket and you won't even notice it's there until you reach for it. It has a 2-way pocket clip. Carry it bezel up or bezel down, take your pick.
2. 80 lumens on tactical level of light, or 5 lumens for prolonged battery duration. Although it is rated at 80 lumens, this little light ourperforms my Fenix P3D, which is rated at a maximum of 215 lumens. It outperforms my Blackhawk Gladius. It outperforms my Streamlight Stinger. ****UPDATE: I just purchased the Surefire 6p LED and G3 LED, both also rated at 80 lumens, and the E1B outshines them both, and it has a better "throw." Maybe Surefire should re-classify the E1B as having more than 80 lumens?
3. Despite being an LED light, the beam travels very far, and it provides an intense bright circle of light at the middle, with a generously wide and bright peripheral illumination area.
4. Runs on a single CR123a battery. This means you can ditch your xenon lights and save all the batteries they eat up for this little guy.
5. Great reflector and super clear lens.
6. It has a lockout feature on the tactical tailcap so that you won't accidentally drain the battery if it turns on without you noticing.
7. Perfect for self-defense (can be used to blind an oponent, and if things get really rough you can use it to put some extra weight on your closed fist and hammer in a stronger punch), great for undercover police officers, backup light for regular police officers, perfect for civilian use due to its small size, good for disasters, and roadside emergencies.
This is pretty much the all around flashlight. You won't really need another flashlight once you buy this one. I think it's definitely worth the price. And if you're good at shopping for bargains, I'm sure if you look hard enough you could find it for under $100 just like I did.
Now you might be wondering what the cons of this light are. What blemishes does it have? The answer is none. This light is perfect. Perhaps the only bad thing is the price, but that's nothing new considering it is a Surefire after all. Trust me, it's worth it!
