Product Overview
Wuben E2 Pulse is a tiny rechargeable keychain flashlight combining a forward white beam with a side COB light, red/blue signaling LEDs and a magnetic base. It weighs 10.7 g with its built-in battery and charges over USB-C. Independent testing measured 102 lumens after 30 seconds on high—below WUBEN's 150-lumen rating—so this is a short-range carry light, not a high-output torch.
What Stands Out
WUBEN fits three lighting roles and a magnetic tail into a 41.4 mm body. Specialist reviewers measured its output and runtime rather than relying only on the 150-lumen label, and found the non-replaceable 120 mAh battery is a more meaningful ownership limit than the tiny size suggests.
Why It Matters
The E2 treats signaling, close-up side light and hands-free mounting as part of a keychain tool, not only as extra brightness modes. Its measured output and short high-mode run time make the intended scale of use clear.
Best For
People who want a light they can leave on keys or a bag for brief close-range tasks, with a side light and magnetic mounting option.
Not For
Users who need sustained high output, a replaceable battery, a dedicated camping or search beam, or a light safe for underwater use.
Things to Know
WUBEN rates the main light at up to 150 lumens; 1Lumen measured 102 lumens at 30 seconds and 78 lumens at 10 minutes on high. Treat the rating as a maker specification, not the independent result.
The 120 mAh lithium-polymer battery is built in and not replaceable. 1Lumen measured about 1 hour 10 minutes for a full charge; its high-mode test ran for 36 minutes before shutoff, with output reducing over time.
WUBEN rates the body IP66 and 1.5 m impact resistance. The manual says it is not designed for underwater use; do not treat IP66 as a submersion rating.
Package contents vary by listing: the manual's standard E2 box omits the P5 quick-release attachment, while the current WUBEN product page describes an E2/P5 bundle. Confirm the selected package before ordering.
The global WUBEN page showed a US$19.97 listing when checked, but price, delivery destination, duties, return eligibility and warranty terms can vary by region. Confirm the local terms; shipping for service may be customer-paid.
The manual warns against shining the high-brightness beam directly into eyes and against using the light while hot inside fabric or heat-sensitive storage.

Second model-matched test reports its own DIY lumen-tube measurements and states readings may be about 10% off; it corroborates roughly 101 lm at 30 seconds, declining high-mode output, run times, beam distance and the built-in-battery trade-off.
