Waterproof, impact resistant, measuring under 2-inches long, and weighing just half an ounce with the battery, Olight built the black I1R II EOS Rechargeable LED Keychain Light to be the last keychain light you'll ever need (or want).
Utilizing the latest in Chip Scale Package (CSP) LED manufacturing technology and a Total Internal Reflection lens system, more of the emitted light is captured and delivered out of the light than conventional LEDs in a smooth beam defined by a bright center cone and generous spill without holes or hotspots. A small twist of the head activates the low mode and a further twist changes to the high output. Keeping with its simplistic design, the custom-designed rechargeable 6mAh 3.7V lithium-ion battery charges in the light using a covered micro-USB charging port that allows you to maintain the waterproof rating without having to disassemble the light to get to the battery. Micro-USB charging cables are fairly common for many phones and small electronics, so Olight opted to leave it out of the packaging on this model of the I1R II. This iteration of the flashlight comes in clamshell packaging.
