I have been using this light for a week or so and here are my impressions.
This light was won in a giveaway, linked here:
Romisen RC-G2, Cyansky P10, Eneloop, Cyansky P10, Klarus P1A
All 1AA lights
It is a very bright light for being a 1AA light. Probably 200-300 lumens, though i don’t have the ability to test the lumen output. I would be interested to know the result if someone else tests it. It does appear to be at least twice the brightness of the other two lights pictured above (100 lumens-ish).
The P10 is a forward clicky meaning you can get momentary on without a full click and can select the mode you want before full click. With this light all you usually need is high since it can’t tailstand.
On high it steps down after about 4 minutes but can be popped back to high until the battery is empty. It may be temperature regulated, but when holding it in your hand it never gets hot, when “tailstanding” in an 18650 battery holder it gets fairly warm.
The bezel is not crenellated, thus if on its head you can’t tell if it was left on.
It opens at head and not the tail, thus it is more likely for muggles to insert battery incorrectly. I have not tested if it has reverse polarity protection.
I’m not sure what the CRI is, i don’t think its high a CRI LED chip.
I’m not a fan of clips so i removed it right away on the green one, took some anodizing off with it. I tried wedging some plastic in before i removed it from the red light but still lost some anodization. It might be a nice idea to not preinstall the clip at the factory.
The lanyard attaches to the clip so if you remove it there is no way to attach the included lanyard.
Size comparison to 21700 battery and 18650 battery. Interestingly the head is almost the exact width of the 18650 battery (excepting the flaring at the bottom of the head).
The CE marking is missing on the red light. Frankly the light looks better without it though i assume it is also CE compliant?
The story of the green Cyansky P10:
It was the first one i was sent, it has a defective switch. It worked a few times then stopped working. Then a few days later worked a few times, then stopped working again, then later on worked again. This pattern perpetually repeats.
Cyansky was nice enough to send me a replacement light (the red one).
Sometimes even when it won’t work when clicked you can get it to work forward clicking but then turns off once you get to a full click or release the holding it down hard that sometimes makes it work. Not sure what this means as to what the defect is?
The back of the head.
After getting the second light i realized i could use the green one as a twisty light, when the switch works leave it on and use the head to operate it. You can even change modes this way. Though i have to remind myself not to accidentally use the switch.
I can’t figure out how to remove the switch to replace it (not that i have a replacement handy). I tried pressing hard on the switch with no battery present to get it out but that didn’t work. My phone camera is not good at getting a down the tube pic thats legible but it does not appear to be screwed in.
Overall the Cyansky P10 is an interesting no nonsense light with good output on a 1AA battery. It will not accept 14500s, but then again i don't use them anyways. It would make a very good light for stashing in the car and in small spaces and runs great on rechargeable NiMH batteries.
Its very small size is an interesting feature.
If i have more new impressions in the near future i will add them below.
