Fenix E15 Review 2025
Compact Yet Durable Design
The Fenix E15 is often described as “tiny but mighty,” and for good reason. Measuring only 2.6 inches and weighing just 1 ounce (without battery), it’s one of the most compact lights in Fenix’s lineup. The body is crafted from aircraft-grade aluminum, with a Type III hard-anodized anti-abrasive finish, offering durability and resistance to corrosion.
Its IPX8 waterproof rating ensures it can survive underwater (up to 2 meters for 30 minutes). If you’re interested in how flashlight bodies are designed for toughness, read this Parts of a Flashlight guide.
Brightness and Output Modes
Powered by a Cree XP-G2 R5 LED, the E15 can output up to 450 lumens using a 16340 rechargeable battery. The light features 4 brightness modes:
- Turbo: 450 lumens
- High: 110 lumens
- Mid: 50 lumens
- Low: 8 lumens
You can toggle between modes by simply twisting the flashlight head—no buttons to break, no complicated settings.

- 16340 rechargeable Li-ion for full 450 lumens
- CR123A lithium for longer shelf life (up to 10 years), but lower output (270 lumens)
For long-term storage or cold climates, the CR123A is ideal. Learn more about flashlight battery types and their pros and cons.

The E12 is more budget-friendly, especially if you prefer AA-powered flashlights, but can’t match E15’s brightness.
💡 Fenix E15 vs. ThruNite T1
The ThruNite T1 outputs up to 1500 lumens with a side switch and magnetic tailcap, making it great for hands-free work. But it’s more expensive and less simple than the E15.
