This flashlight produces a beam with a visible dark spot in the middle at close range. I dont have any other big smooth refelector with XPL-HI flashlight so i’m not sure if this beam pattern in close range is normal, but i couldn’t find any defective in this light. Please let me know your opinions about this problem.
Thanks
Throwers make a donut at short range when properly focused.
So what you think is a failure MIGHT be a good sign.
Does the donut disappear at, let’s say, 2 meters ?
This is my first flashlight with Xpl-hi and big smooth reflector, so i’m just not sure this donut beam is normal, I have a convoy s2 with xpl-hi and smooth reflector, it doesn’t have this donut beam, and hotspot is even. This C8+ donut beam does disappear at longer than 1m range but the hotspot is not even as of the s2. Anyway this light is supposed to be used at long range and it is very good at this
I don’t have the Convoy C8, but regarding XP-L Hi and donut holes… I’d like to mention on my Astrolux S2, by default with the LED plastic centering ring installed, it will produce a donut hole shape (when at closer ranges); but if I remove the plastic centering ring, the donut hole then disappears (or becomes more faint). Not sure if the same might happen on the C8.
This is exactly what i thought because i noticed the led in c8+ is deeper under the reflector than in my convoy S2, but i didn’t tried to remove the centering gasket. After your comment, I tried to remove the gasket, and guess what, NO MORE DONUT BEAM!! and the hotspot is more even, and a little more thow (i guess). Thanks for your suggestion :+1:
In my C8 with dedomed XP-G2, should not behave much different from a XP-L Hi, the donut hole is completely gone at 50cm, the hotspot is nice an smooth then.
Small video:
No no no. The hole should be there at short distances, the beam has not formed yet, you actually see the hole in the reflector where the led sits. My C8 from the video has a perfectly focussed led.
