I’ve been using the Aurora A8 for about a year now & appreciate the very small size. My only gripes with it are the very small battery (which means limited runtime) and some visible PWM in lower modes. It’s otherwise a terrific little light.
RovyVon has introduced a successor to the A8 — the A9. It’s not having a translucent body, but builds upon the A series design with an improved switch, increased brightness, and a larger battery. The A9 doubles the A8 battery capacity. There’s also a larger A28 model that looks like an enlarged A8, minus the colored side strobes. It features a much larger battery—600mAh—so it’s also not really a keychain light due to the increased size.
For some, the lack of a user replaceable battery has been a deterrent, but now the A29 made of brass features a removable 600mAh battery. Of course, it’s a proprietary battery, but at least it can be replaced if the current one ever fails or falls below acceptable performance.
