What owners report
Olight Obulb Pro
- ✓Genuinely useful and versatile as a soft area light for tents and bags
- ✓1,650mAh cell — well over double the original Obulb's capacity
- ✓Bluetooth app control that works and is occasionally handy
- ✓Bigger than the standard Obulb, which reviewers found an improvement
- ✓Simple, robust object with nothing to break
- ✗The MCC charging cable isn't included by default — you must order one
- ✗The Osling carrying accessory doesn't fit the Pro
- ✗The app wants a unique login and permissions including microphone access
- ✗One reviewer couldn't revert a custom app image back to the stock one
- ✗Proprietary charging on a device that would suit USB-C
Olight i3T EOS
- ✓Genuinely disappears in a pocket — light enough to forget
- ✓Runs on AAA cells you can buy anywhere
- ✓Excellent tail switch with a clean action
- ✓Moonlight mode low enough to preserve dark adaptation
- ✓Among the brightest dedicated AAA lights, with a durable aluminium body
- ✗Cool white with no high-CRI option
- ✗No lithium-ion support and AAA cells don't last long
- ✗No keyring attachment on the light — you have to use the clip
- ✗Can't tailstand because the switch protrudes
- ✗No lockout at all; unscrewing the tailcap doesn't disable it
