YSMART Launches BULLET3: A 3cm Micro Keychain Flashlight with Pro-Grade LEDs

YSMART, the creator of compact everyday carry tools and keychain flashlights, has launched its newest Kickstarter campaign: BULLET3, a 3cm micro flashlight built for serious everyday performance.

Now two weeks into the campaign, BULLET3 has already gained strong traction, with more than 400 backers and over £26,000 funded. Designed as YSMART's smallest Bullet flashlight yet, BULLET3 combines a fingertip-sized body, IPX8 waterproof protection, premium metal materials, and pro-grade LED performance in a tool small enough to stay on a keychain every day.

Following years of experience across multiple flashlight campaigns and support from thousands of backers worldwide, YSMART designed BULLET3 to take a different direction from its previous magnetic quick-release models. Instead of adding more mechanisms, BULLET3 focuses on simplicity, size, waterproofing, and light quality.

At just 3cm long and starting from 5g, BULLET3 is designed to disappear on a keychain until it is needed. It is small enough for daily carry, but built for real everyday situations — unlocking a door at night, checking inside a bag, finding dropped items, walking outdoors, camping, traveling, or keeping a backup light close at hand.

The twist-style operation keeps the design simple and reliable. It also helps BULLET3 achieve its compact size and IPX8 waterproof protection, making it ready for rain, splashes, wet outdoor use, and unexpected conditions.

One of BULLET3's biggest upgrades is its LED selection. The 6500K Cool White version uses a CREE XP-GR LED, chosen for its round light-emitting surface, which helps create a cleaner, smoother, and more focused beam through the optic. The 4000K Warm White and 660nm Red Light versions use Luminus SST-20 LEDs, giving backers lighting choices for different real-world needs.

Cool White is designed for crisp visibility and outdoor tasks. Warm White offers a softer and more comfortable beam for close-up use. Red Light helps preserve night vision for camping, fishing, photography setups, and low-light environments.
