The Wuben E2 Pulse is a coin-sized keychain flashlight reviewed by CommQuest that packs a 3-in-1 lighting system into a body small enough to forget you’re carrying it. It covers everyday illumination, utility lighting, and red-and-blue signaling, making it a genuinely practical EDC pick for the size.
What It Actually Is
The E2 Pulse is built around the idea that a keychain light should do more than just exist. It runs three distinct lighting setups in one tiny package: a main white light for general use, a side-facing white utility light that also has a heartbeat breathing mode, and red and blue signaling lights. That last part matters more than it might seem at first glance. Most pocket lights stop at white. This one doesn’t.
It also has mode memory, so it returns to the last mode you used instead of making you cycle through everything from the beginning. Multiple brightness levels let you dial in exactly how much light you need. And it clips onto a keychain, hangs from a necklace, attaches to a backpack strap, or rides on a waist clip. Flexible carry options for something this small is a genuine plus.
What CommQuest Actually Noticed
The review zeroed in on the practical moments where each lighting mode earns its keep. The main white light is exactly what you reach for when you’re fumbling with a lock in the dark. The side utility light handles the lower-angle tasks well, things like digging through a bag or checking under a cabinet, without throwing light directly in your face. That side orientation is a small but smart design choice.
The red and blue signaling lights address a real gap. Most keychain lights are tools for finding things. The E2 Pulse also covers situations where you need to be found, or where you need to signal someone at a distance. That shifts it from a convenience item into something with actual safety utility.
The size came up repeatedly in the review because it’s genuinely part of the pitch. Coin-sized and light enough to forget about until you need it. That framing is honest. The best EDC gear is the stuff you stop noticing until it matters.
Who This Fits
This light makes sense for anyone who already carries keys and wants a light that won’t add noticeable bulk or weight. It’s also a reasonable pick for outdoor use, travel, or any situation where having a signaling option alongside a regular light is worth something. The multiple carry methods mean it works whether you prefer a keychain setup or something attached to a bag.
It’s not trying to replace a dedicated high-output flashlight. It’s trying to be the light you always have on you, and it covers more ground than most options this size manage to.
Honest Take
The 3-in-1 setup is the real story here. A lot of small lights do one thing adequately. The E2 Pulse gives you a main light, a utility light with a breathing mode, and a signaling option, all with mode memory and adjustable brightness. For everyday carry on a keychain, that’s a lot of function packed into a coin-sized body. CommQuest’s take holds up: it’s a smart carry for the size.
