DEVMO LED Tester qllm-a38 Handheld Light Meter 2-150mA for Lab and

Description

Product Overview

The DEVMO qllm-a38 LED Tester is a portable light meter designed for precise evaluation of LED performance. Housed in a rugged plastic shell measuring approximately 8 × 5.5 × 2.2 cm, the device weighs just 0.32 oz, making it easy to carry to any workstation. It features two rows of labeled sockets: the top row accommodates 2‑pin LEDs with selectable currents from 2 mA to 30 mA, while the bottom row supports 4‑pin (piranha) LEDs with currents ranging from 20 mA to 150 mA. A single push‑button operation triggers instant readings of brightness and illuminant color, displayed on a clear LCD.

Usage

Designed for electronics laboratories, manufacturing QA, and DIY hobbyists, the tester simplifies LED verification during prototype assembly or final product inspection. Insert the LED into the appropriate socket, select the desired current range, and press the button to view real‑time output. The device works without external power sources, drawing power from an internal rechargeable battery that lasts for dozens of test cycles. Ideal for testing indicator LEDs, backlighting modules, and custom lighting solutions in automotive, consumer electronics, and industrial equipment.
