This document is the preliminary spec for KASL-4805QB24S/7 LED Light Bar. It introduces the features and characteristics of the product.
The Kingbright KASL-4805QB24S/7 LED light bar is a linear, high‑efficiency device with instant light output and low power consumption. It measures 48 mm × 5 mm × 1.6 mm and complies with RoHS. The document lists its absolute maximum ratings, electrical and optical characteristics, and provides handling and mounting guidelines.
Precautions include ESD protection, recommended use of thermal grease, M2 screws for mounting, and soldering limits. Packaging details describe primary trays (50 pcs), secondary bags (100 pcs) and outer boxes (800 pcs). An application note explains the heat‑sink attachment procedure and current‑dependent thermal requirements.

| Thermal Resistance (Rth j‑c) | 3.5 °C/W |
The soldering iron power should not exceed 40 W and it should not be in contact with the joint for more than 3.5 seconds.
Apply a thin layer (0.1 ~ 0.2 mm) of thermal grease on the bottom of the light bar, press it firmly onto the heat sink, and keep the pad temperature below 75 °C.
The continuous forward current is 700 mA, while the pulse forward current can reach 1000 mA.
Each tray holds 50 pieces, three trays (100 pieces) are placed in a bag, and 800 pieces are packed in a standard 9" box.
