This is a product specification for an LED light bar
This document outlines the key features and electrical/optical characteristics of the KASL-4805QBFS/3 Blue LED light bar, including dimensions, efficiency, and compliance. It also lists absolute maximum ratings such as forward current (350 mA) and power dissipation (4.2 W).
Detailed handling precautions are provided, covering lens protection, recommended thermal grease, screw type, and soldering limits. The note describes the proper procedure for attaching the light bar to a heat sink, including the use of a thin thermal‑grease layer and recommended driving currents for series connections.
| Forward Current (IF) | 350 mA |
|---|---|
| Power Dissipation (Pa) | 4.2 W |
| LED Junction Temperature (Tj) | 110 °C |
| Operating Temperature (Topr) | -30 °C to +100 °C |
