The Panasonic EY37C4 cordless LED work light is a versatile lighting tool for professional applications and DIY projects in poorly lit environments. This non-battery light delivers approximately 750 lumens of brightness with three adjustable lighting modes for different working conditions. The high mode provides 100 percent brightness for about 7 hours of continuous operation, while medium (50 percent) and low (10 percent) settings significantly extend battery life. With a brightness level of about 1500 lux at a distance of 40 cm, this lamp ensures clear visibility in dark work areas. The innovative design features a 180-degree tiltable head with seven fixed positions and 270 degrees of continuous rotation capability, allowing for precisely directed lighting without a full 360-degree turn. Measuring 162 mm in length, 70 mm in height, and 99 mm in depth, the compact housing weighs 380 grams without the battery, ensuring easy handling and portability. Two USB-A ports provide a DC-5V output with a total capacity of 2A, enabling simultaneous charging of smartphones, tablets, and other USB-powered devices while the light remains functional. This dual functionality makes it particularly useful in locations without access to mains power. The integrated carrying handle with a hanging opening offers additional convenience for hands-free operation. Compatible with 14.4V and 18V Panasonic battery systems, this light requires separate purchase of batteries and charger. The robust construction and practical features make it suitable for construction sites, automotive repair, emergency situations, and various professional applications where reliable, adjustable lighting is essential.
