ETC Capella 800 Lumen USB Rechargeable Front Bike Light – IPX6 Waterproof, >200 m Beam (ELA5122)

The ETC Capella 800 Lumen Front Light (model ELA5122) is designed for serious cyclists needing brightness, durability, and versatility. It features a single CREE XP‑L LED capable of generating a luminous flux of 800 lumens with a beam reach beyond 200 m. 

Encased in a compact housing (101 × 33.8 × 30.7 mm, ~125 g) and rated IPX6, it resists heavy water jets—ideal for rainy or muddy rides. 
It’s powered by a 2,500 mAh 18650 lithium battery, fully recharged in about 2.5 hours with a 5V, 1A USB input. 

Build & Design Features
Compact & lightweight: 125 g weight keeps it manageable on handlebars. 
Solid mounting system: Uses a strap + ratchet lock (somewhat similar to Cateye’s FlexTight style), which reviewers note is more secure than typical rubber only mounts. 
Beam pattern: Focused central beam with vertical side lenses to improve peripheral visibility. 
Durability: The IPX6 rating means it handles strong water jets (but not prolonged immersion). 
User experience: Reviewers praised its price‑to‑performance, simplicity, and lack of major flaws at its price point.

Versatile modes (steady, breathing, strobe) give flexibility for day/night or commuting use
