Form factor & size: 2 ft batten light — a compact linear fixture about 2 ft in length. 

Power consumption: 20 

Input voltage: 110 V (suitable for 110 V wiring). 

Emergency Function (Battery Backup): Has built-in battery backup which automatically turns on when main power fails — runs for ~ 3 hours. That gives you temporary lighting during outages. 

Light Output / Brightness: Typical LED battens in this class deliver around 2000–2200 lumens (enough to brightly light a small-to-medium room or corridor). 

Colour & Light Quality: Often around 4000 K — a “neutral white / cool white” — good for general-purpose lighting (workshops, hallways, garages, utility areas, etc.).

Efficiency & Lifespan: LED technology means high energy efficiency (good lumens per watt), and LEDs typically have a long service life (many tens of thousands of hours). 

Durability & Build: Many such battens use a durable housing — polycarbonate or ABS with a diffuser — which protects the LED components, and can often be more robust than old fluorescent tube fixtures.
