This DTEZ work light is a beast when it comes to brightness. It runs on DeWalt 20V Max lithium-ion batteries (like the DCB205, DCB204, etc.) and even works with the 60V Flex batteries. With 4200 lumens at max, it lights up everything. You get three modes: spotlight (1800LM), floodlight (2400LM), and both combined (4200LM)—just click the button to cycle through. The light head is made from zinc alloy and is about 9 inches wide, packed with 84 LED chips, so it's tough and bright. It's perfect for emergencies, camping, working in the garage, or even walking the dog at night. Oh, and there's a USB port on the bottom (5V/2.1A) so you can charge your phone or other devices while you're out. It's compatible with most DeWalt 20V batteries (note: not for the older 18V XRP ones). If you already have DeWalt tools, this light is a no-brainer addition. It's durable, crazy bright, and super useful. Definitely a handy tool to have around.
