I bough mine on August the 3rd. It is still in Processing. Customer servicer doesn’t help either. I can either get a refund or exchange for something else. But I really want it. Hahaha.
Received mine. This thing is like a little laser, excellent but not very useful when using it at short distance. But its so powerful you can even use it during daylight to illuminate something under shadow.
Also its weird how there is no difference between the 30% and 100% mode, with the SST-40 there is a very small difference only noticeable at long range, definitely not worth wasting the battery life.
I see a clear difference from the low, the other 2 modes are a little bit harder to tell but the 100% is definitely the brightest
(wainlight, to be clear)
Just received my Convoy C8+ with the NM1 TG Osram in it, from Aliexpress.
Gotta say I’m a tad disappointed………it’s got a lot of nasty corona!
And I mean a lot!!!
It’s not a particularly good pic, it’s from an iPhone 10, and excuse the wall, it’s just been stripped of paper as we’re decorating, but as you can see, on 30%, it just doesn’t look right!! It looks a little green doesn’t it?
Maybe you might want to check it outside during a night walk to see if it is that bad. Judging only from this photo is not possible imho. A general rule of thumb however, the better the CRI of the emitter, the less ill-looking the corona.
E.g. I have Convoy C8+ with 95CRI SST-20 4000K, and I had no issues with the corona at all. I had one with 65-70CRI Cree XM-L2 5000K, and that was spectacularly lot worse.
Corona quality also depends on the radial tint shift of the emitters by manufacturing technology. I am not aware, that Osram NM1 emitters are bad in this matter, but e.g. Cree XP-G3 or XHPxx.2 is definitely bad at this (for them, even the 90 CRI variants are horrible). However, even “standard CRI” XP-L HI or XHP35 HI emitters are almost flawless regarding the corona.
Apparently, not any of these super thrower Osram white tints are high CRI, just around 65-70. I would be also happier, if Osram ever considered making high CRI of these - but I didn’t have one of these whites, I was scared by the blue spike in the spectrum diagram, which was provided by the manufacturer.
Hi Adam, my worry is that I took that pic at around 4m from the wall, and that at a longer range the corona will affect the hotspot (which is a nicely rounded one at that)!
I was going to buy a Wainlight C8+ to run as a comparison, but, they all look the same so to me I’m making an assumption (probably a wrong one) that they all have the same manufacturer, and are just rebranded!!
I’ll wait until dark and try it then, if I’m dissatisfied, it’ll be returned, simple.
Oh and the glass was a little dusty too, a resold return perhaps?
The corona is normal, the LED phosphor is not perfectly at the middle by itself if you look closely. I don’t have this green tint, maybe its a faulty LED or its a different tint. Are you sure its from the official Convoy store? There is many fake stores.
This C8+ with osram are not in use on small distances. But in long range are better than SST40 and XPL HI. Just it’s very little long range thrower. If you wanted near distance thrower you must get SST40 or XPL HI. They have no problem to be useful in distance bellow 50m.
Hi Degman, I’m a long range thrower type myself, I have a TN42 for the longer ranges but it’s a bit big, I have an FT03 (SST-40 W) too, which is my current ‘go to’ flashlight, I bought an E10 recently also, good but it’s not breaking any records, so that’s me EDC ‘close quarters’ tool. I wanted a small but big thrower………hence the C8+ purchase!!
Hello Omega, I think, only think, the green tint in the corona may actually come from A) the iPhone camera, and B) the actual wall!!!
I’m going up to a place in the hills (if it hasn’t been Corona-Closed) that has little or no light pollution, I take all my flashlights there, and I’ll see what’s what then!
Will keep you informed!
Regards
Rob
EDIT: I just ordered another C8+ from NealsGadgets!!! To run a comparison!
Stockton-Rob: any update on the Convoy C8+ with OSRAM?
I just got mine in from Simon’s store. When shining it at the wall in an apartment (maybe 2 meters away), the hotspot and corona appear to be overlapping. I can see the hotspot, but there’re three egg-shaped coronas on top of it.
Definition of hotspot and corona fromhere: Beam Anatomy
Any way to overcome this on my own, before sending the light back to China? I’ve tried to take out the reflector and centering ring, then putting it all back together. Same result.
I did exactly what you did, I unscrewed the reflector, removed it, use an air bulb lens cleaner to rid it of dust….then gently screwed it back together, pointing it vertically, until I got less of a corona, it was a pain in the butt to do, but I’m happier with it now.
I did however also buy a Manker U22-II, thinking it would out-throw my Convoy, they’re very similar, but the Convoy hotspot was better…oh and the Manker has corona too.
Egg shaped coronas, three of them, doesn’t seem right.
Try the vertical screw/unscrew method first, tilt the flashlight accordingly to the corona, if it forms on the left, tilt it to the right etc.
Hope this helps, if not, send it back as defective!!
That’s normal…the smaller the led, the harder it is to center perfectly, it’s extremely difficult and I build my own and struggle. The much more expensive Noctigon K1 has an off center led, but still performs well.
Did you buy it to shine at a wall? Does it affect your use outside?
If it’s badly off center then loosen the mcpcb screws and correct it by pushing it while tightening the screws.
We at blf asked Simon to use these leds…can’t then start complaining about this issue, it can’t be helped, especially at this price point
The egg shaped coronas are normal with this led, entirely different than the normal in your link
