A keychain light has two jobs: fit in a pocket and be there when it’s dark. The ACEBEAM Keylite 500 (sometimes mistyped as Keylight) is a USB-C rechargeable light that squeezes dual LEDs into a 19-gram body. This post draws on ACEBEAM’s product page and official video, and we have not tested it.
The specs
ACEBEAM lists a maximum of 500 lumens from dual LEDs, a 70-meter maximum throw and 1,225 candela peak intensity. Modes are Moonlight at 1 lumen (up to 12 hours), Low at 10 lumens, Medium, High, Turbo and Strobe. It charges over USB-C in about an hour. Weight is 19 grams and dimensions are 60.5 x 16 x 10.5 mm.
The body is CNC-machined AL6061-T6 aluminium, with an IP66 rating and a 1.5-meter drop rating, which makes it more weather-ready than many keychain lights.
Who it suits
It is for people who want a light on their keys all the time, whether that is walking the dog, finding a lock at night or fetching something from the car. The very low Moonlight mode is useful when you do not want to wake anyone.
Drawbacks
ACEBEAM says the 500-lumen Turbo mode lasts only about 20 seconds before stepping down, so 500 lumens is a burst, not a sustained output. The page also does not publish battery capacity, which makes comparing runtime with other lights harder.
Where to find it
Search for the ACEBEAM Keylite 500 on Amazon. Since it charges by USB-C, a power bank works as a backup charger.
Bottom Line
The Keylite 500 is a compact, weather-rated keychain light with a useful low mode. Just remember that Turbo is a short burst, and plan around the lower modes for real runtime.
FAQ
How bright is the Keylite 500?
