I picked up the latest RovyVon Aurora A5x (A5u) in the recent anniversary sale ($22). It has a 330 mAh battery in it, almost triple the original 130 mAh that RovyVon had been using in the first release of the A5 and A8 (as noted in the review).
Size-wise it’s a good bit thicker, maybe 40~50%. Based on the original size this is still a small keychain EDC. The Cree XP-G3 pumps out 650 lumens, while the Nichia puts out a modest 450 lumens. Frankly, for a keychain light, you really don’t need much more than a few hundred lumens for max.
I wonder if any improvements had been made to the GITD version of the polycarbonate casing. I bought my A5u with UV LED. It’s actually just one LED and it’s flanked by two white LED’s that all come on at the same time. No, this really isn’t designed for verifying currency. However, I did note the “black light” effect, where things like Post-It notes and white towels “popped”. Anyway, the main idea was to use it for boosting the GITD output. In fact, RovyVon recommends it for that purpose. And in the initial moments it’s nicely bright. But wow… it fades off very quickly. Within 10 minutes it’s very faint. After about an hour, you can barely detect the GITD glow. This is a stark comparison to the GITD inserts I use on my FW3A. So really, in essence, this feature is something you use for “the moment”. Such as putting down your light (with keys, supposedly), hit the GITD with UV for a few moments, leave it… then come back within a half hour expecting the GITD to help make retrieval easy. Or, if you’re carrying a bunch of things for a distance in the dark, illuminate it with UV to charge, then if you manage to drop the A5 along the way you’ll find it easily.
Maybe it’s the limitations of this premise—using GITD polycarbonate for a flashlight casing, where part of it needs to be transparent for side LED’s. I know for a fact that totally opaque GITD flashlight bodies perform better than this.
One other thing that surprised me… is the LED status indicator for charging. Instead of using a dual color LED (or two very small ones side-by-side) for red and blue, charging and charged respectively, RovyVon decided on going with a single blue LED. While charging it “breathes”. When it’s done, the blue LED is constant. And the intensity is VERY bright. It lights up a dark room. Frankly, that’s a disappointment. Why ruin a good thing? The red LED for in-process charging is a standard for most flashlight makers. And it doesn’t need to be so blinding bright. At least RovyVon didn’t muck with full use of the A5 while it’s charging. All functions operate.
Big win: NO visible PWM! That was my real pet peeve with the original A8. So nice to see it gone. I’m presuming that means it’s also gone in the latest A8.
One oddity, though: When you double-click, it turns on the light in “memorized mode.” By default this is “low.” And the instructions don’t say anything about how to set it. Turns out it’s done by leaving the light on for 3 minutes. That includes turbo. So guess what? If you’re an “ultra low” kind of person, and you use a brighter mode for more than 3 minutes, you have to let the light sit on ultra-low for 3 full minutes for that to be restored as the default.
