Wuben G2 Review (500 Lumen, P9 LED, Flat Keychain Light)

Wuben has a new flat keychain style light out with the G2. It’s a little different with the LED being on the flat side, with a wide large reflector, USB-C rechargeable, and can crank out up to 500 lumens in turbo.

Packaging  & Accessories

The packaging is a nice clear box, with the product labels being stickers on the top and bottom. Inside the box includes the light, USB-A to C charging cable, a gray plastic clip, and manual. 


Construction & Design

The G2 is flat light, with the reflector on the flat side. Its body is made from aluminum and is available in 3 colors currently, black, Blue, and Green which I have here. The ends are both plastics. At the bottom end there is a plastic keychain ring that twists on and off, it can be a little tricky to put back on. Under this is a magnet that is strong enough to hold the light vertically on a painted metal surface without an issue. 

In the middle is the P9 LED and TIR optic. On the sides there is the connection point for the pocket clip which I will talk about more in a minute. 


At the top is the USB-C charging port. It has a silicone flap covering it. It’s not a very tight fit. The light doesn’t have a dust or water rating as a result. This is an area for improvement in future versions. Next to the charging port is the switch. It sits nearly flush and I had no issues with accidentally activating it.


Retention & Size

Size here is 2.3” x 1” x 0.36” thick without the clip. Weight is 1 ounce without clip. There is no water or dust rating officially for the light. With that flap I think it would probably struggle to meet the standard specs.

Retention options include a plastic clip that clips on the rear of the light in some indentions. This isn’t necessarily a light or clip designed for front pants pocket EDC but more to strap on to a bag, hat, etc. The clip is stiff. It also has a split ring attachment that twists off to reveal a magnet underneath too. 



The UI on the G2 requires a Long press to turn on when the light is off. This really mitigates accidental activations in my experience. The light has a memory mode to the last previously used setting. To adjust between the 4 modes when turned on, just press the button. The double press goes to turbo.


LED & Beam

The LED being used here is an OSRAM P9 LED. My Opple meter measured 6050k at 68 CRI as well as some PWM on high. The beam is mostly flood with a small hot center thanks to the TRI style optic. A good beam profile for up-close work for a light this size. 


Outputs, runtimes, temps

Official outputs on Turbo were 500 lumens, and I measured 437 lumens initially, with a fast decline in under a minute to around 190. High is rated at 200 lumens, I measured 190. Medium is rated at 65 lumens I measured 61 at 30 seconds. Max heat I saw on the body of the light was 36C near the end of the runtime. Total runtime starting in Turbo was 40 minutes as well as in High mode. Medium lasted out to 2 hours of runtime which is longer than quoted. 



Internally the light contains a 280mAh lithium polymer battery. When I tested the capacity I got slightly more than this at about 314mAh. The total charge time here via USB-C was 1 hour. The light is USB-C PD compatible but you don’t get any benefits of the charging speed here with such a small battery. There is a small LED near the button that goes red when charging, and blue when charged. 


Final Thoughts

At less than $20 with my discount coupon, the G2 is a decent keychain light. I like the small thin nature, it’s smaller and thinner than most car key fobs and produces a good amount of light for its size. It’s smaller than some of the Nitecore lights I have like the TIP which is similar but larger than some of the Royvon lights. 

I don’t like that the silicone port covering the USB-C port is more of a flap. It’s not really a seal, and the light carries no water rating as a result. I did pour some water on it in the sink and it was ok, but it definitely won’t survive a full submersion. Hopefully, they can come up with a better cover in the future. 


It has a really broad floody beam but with a super small center hots spot, thanks to its TIR optic. It works for the close-range tasks it’s designed for pretty well. The cool white LED isn’t my favorite but it works. Overall a decent keychain light for the money.

Packaging & Accessories

Packaging is a simple black box with a line drawing of the light on the outside. The box has a black and orange theme, it is printed to reflect the LED that’s in this light with a sticker on the back telling you which version and body color you have here. 

Accessories are limited and include the light, pocket clip thats preinstalled but removable, and a 6” USB-A to USB-C cable along with a manual and warranty card.



The Aurora A33 is made of aluminum and in my example is anodized in green. Several other body colors are available including Black, Gunmetal, Red, and Desert Tan. Starting at the rear it has a flat metal button with a nice machined circular pattern in it for a bit of texture for the eswitch. There is a ring around the button that makes it sit slightly recessed, this also helps protect the button too. It feels a little odd but does help you locate it and helps keep from turning on in the pocket. The button is does have a bit of a vague feeling to it that I am not a huge fan of but does has a nice click. 


To access the charging port the  rear tail section unscrews slightly. This is easier shown then described but it’s best to grab the tail section itself not the clip since the clip rotates more easily. Once unscrewed the USB-C port is exposed as well as a LED indicator when recharging. There is an oring to keep everything sealed


The body tube has some spirals milled into it for texture and style. These are better then normal knurling visually but could be a little more aggressive in my taste. The body tube and head are one piece with the front bezel being glued in place it looks like. The front features a glass lens and TIR style optic. Internally there is a 600mAh LiPo battery sealed inside the light. This is non user replaceable battery. 



The primary method of retention is the included deep carry pocket clip on the A33. It’s a clip on style clip and can be removed if you want. The unfortunate thing is here that it does spin around the light with a little bit for effort, I wish it was a bit tighter fit. It’s a fairly wide and substantial clip, and the steel is springy. It’s reasonably secure in the pocket but I wish it was a little stiffer so it was more secure. There is a small step in the clip that your pocket can snag on. That said I am a fan here, the clip overall is better then 85% of flashlights I review. 


Size and Weight 

I measured the length of the Aurora A33 at 119mm, maximum diameter tail at 16.5mm, minimum diameter at the body at 14.6mm. Weight with the clip installed is 42.2g. The light is IPX8 rated which I did test overnight in a glass of water.


LED & Beam Shots

The Aurora A33 is available with 2 LED’s I have the Nichia 219C at 5000k and 90 CRI, but a Cree XP-G2 with cool white, and about 20 more lumens (200 lumens total) on it’s highest output if you prefer. The light is using a TIR reflector and produces a medium sized hot center and a medium amount of spill. It’s good for this style of light where your mostly going to be using at short and medium distances.


Aurora A33 on Left, Nitecore MT06MD


There is some PWM that my scope noticed here, it’s fast and not noticeable to my eye or camera. But the scope does catch it. 

Output modes on the Nichia model are officially rated at 0.5 Lumens, 15 lumens, 60 lumens, and 180 lumens


Heat and Runtime

The light has 4 modes, and I did runtime graphs for the two highest modes. On high, the light lasts for a total of 88 minus, the first 12 minutes are above 90% relative output and you see a slight step down in output. At the 45 minute mark your still producing 80% of relative output. After this though you see a sharp decline for the remaining amount of time. Highest temp I observed was around 36C at the 40 minute mark.


In medium the light lasts an impressive 5:48:00. It an long S curve making me think there might not be much regulation on this mode. That said it was running at 60% relative output out to the 2:50:0) mark. 



UI here is mostly simple as long as you remember you have to long press to turn on the light. Once on single presses will allow you to go up in the 4 modes. Long press to turn off. There is no memory modes and you always start at the bottom of the mode range. Which changing modes I did notice that I had to give it some time to go up the range, I couldn’t click fast or double press to go up the range faster. That’s a little annoying, I would love a double or triple click to turbo here. 


This is a revised UI than this light originally shipped with, and Royvon has yet to update their website to reflect this but I confirmed this with the company. 


When the power does get low you do get a red LED indicator that comes on, however this LED is normally covered with the top of the cap that covers the USB-C port. 



Recharging is accomplished via USB-C onboard the light. It will charge via USB-C to C. To get to the charging port the tail cap must be unscrewed a bit. This is a little hard to do due the oring seal and the facto the pocket clip rotates fairly easily. Once open this will expose the port and charge status LED. When low on power (10% remaining) this light will remain red. When charging it a slow fading blue LED and when charged it’s solid blue. Total charge time on the internal 600mAh LiPo battery was 1:02:00. Max charge rate was .52A.

The light will work through all modes while charging but the button to turn the light on is hard to press, especially if you have larger fingers. 



  • Neutral white, high CRI emitter option is available. Nice choice with the Nicahia 219C LED.
  • Good deep carry pocket clip, I wish it didn’t rotate as easily and was a bit stiffer.
  • Affordable and available in a good variety of colors.



  • Built in battery is non user replaceable. 
  • Takes slightly longer to turn on with the long press to on then I would like but it won’t come on accidentally this way.
  • The instructions talk about 2 modes on the later models like I have this has been eliminated for simplicity.



I like the Royvon Aurora A33 as a pen format sized light. It’s got the enthusiast in mind with a number of body colors and a neutral high CRI LED option. The Nichia 219C in 5000k is a great choice here for a number of tasks.

I like that it has onboard USB-C charging as well, it makes it convenient to charge and fairly quick. The UI here is good, not great, and I would say the same with the pocket clip, I would just like it to be a tad more secure.

Overall as long as you don’t mind the sealed battery I think this the best pen light I have reviewed in a few years. It’s affordable, has a choice of LED, and body color, good clip and just an overall well rounded package that I can recommend.
