Quick answer
Choose the Radiant 100 keychain flashlight for a simple, always-ready battery light you can clip on and forget. Pick the Radiant RF7 rechargeable flashlight when you want more brightness, multiple modes, and USB-C charging in a similar keychain size.
Battery vs rechargeable: the core trade-off
The most obvious difference between these two small flashlights is how they get power. The Radiant 100 uses a replaceable battery, meaning you can swap it in seconds and keep using the light for years without worrying about charging. The Radiant RF7 has a built-in rechargeable battery that charges via USB-C, so you never need to buy or carry spare batteries—but you do need to remember to charge it.
If you want a set-and-forget tool that works even after years in a drawer, the battery-powered Radiant 100 is more reliable. If you prefer the convenience of plugging in and want higher output, the rechargeable RF7 is the better everyday choice.
Brightness and modes: more than just lumens
The Radiant RF7 puts out 300 lumens and offers 7 different modes, including a multicolor body light. That makes it far more versatile than the Radiant 100, which has a single brightness level. For tasks like reading a map, signaling, or using a red light to preserve night vision, the RF7 gives you options the 100 simply can't match.
That said, more modes mean more complexity. If you just need a simple on/off light for finding your keys or walking to the door, the Radiant 100's straightforward operation is actually an advantage.
Size and carry: both fit on your keychain
Both flashlights are ultra-compact and include the S-Biner MicroLock for easy keychain attachment. The Radiant 100 is slightly lighter and more minimalist, while the RF7 adds a hands-free hat clip and a multicolor body light without becoming bulky. If you want the smallest possible keychain light, the Radiant 100 edges ahead. If you want extra features without much more weight, the RF7 is still very pocketable.
Trade-offs at a glance
- Power source: Radiant 100 uses replaceable batteries (always ready, no charging needed). Radiant RF7 uses USB-C rechargeable battery (no battery purchases, but requires charging).
- Brightness and modes: Radiant 100 is a simple single-mode light. Radiant RF7 offers 300 lumens and 7 modes including a multicolor body light for more versatility.
- Extra features: Radiant RF7 includes a hands-free hat clip and multicolor body light. Radiant 100 keeps it minimal with just the flashlight and keychain clip.
- Reliability over time: Radiant 100 works as long as you have a spare battery. Radiant RF7's rechargeable battery will eventually hold less charge after years of use. If you want a light that works after a decade in a glovebox, the Radiant 100 is more dependable.
