New Convoy C8 – Clearly better

Hmmm, we’re these all older lights? I’m pretty new to the flashlight world so I’ve only seen stuff fairly new.

It looks like the Gray C8 may come with a smooth reflector as well. But the AR Glass, Biscotti, and XP-L HI are not there by default.

I ordered another c8 with everything on it and asked Simon for other button and black body color. As before, he said no problem and gave me a discount :slight_smile: Probably the best seller i have seen

I have “tested” the beam of my Klarus xt12gt, c8 and Fenix rc20. Fenix has the worst beamshot. Klarus is the best, but is getting hot on max output. C8 is not far away from Klarus beam distance.

hm the klarus says a bit over 600m throw, can the c8 with xpl hi really come close to that? its more around 300-350m throw at most no? either way the convoy wins any day if u look at the price and what u get, clear winner to me.

Yes it says 600m. How to post pictures? Cant add them.

They need to be on a website, first. Then you take that pictures url and copy paste it into the pop up box when you click the orangish sunset looking button above the post window.

Or just add ! in front of and behind the url.

Fenix

Klarus

Convoy C8

Woah! Big pics.

Another trick is to set the width to 95 when you have big pictures. You have to use the popup box for that.

Quote my post and you can see how the width is added on.

@JasonWW thanks did edit my post. Was hard to post pictures with my phone.

That Klarus does seem brighter than the C8.

Yes it does, but after some time it also gets hotter than Convoy. For my needs (job) the Convoy is a great flashlight. If only i would find the Convoy before purchasing the Klarus :wink:

I had to look up to see what that Klarus model was. It’s got an xhp35 at 1600 lumen. That’s about 14w.

The C8 has an xpl at 900 lumen. That’s about 10 watts.

That’s why it’s brighter and gets hot faster.

A friend of mine just got in some XM-L2 U4 0D emitters, found that de-doming with Coleman lantern fuel left the tint very nice and it came clean in about 20 minutes. He used it in an L2 and absolutely loves the result! :slight_smile:

Jason, just looking at the wattage isn’t the whole picture. The efficiency of the emitter at a given output will change how much of the applied wattage is light and how much is heat. When overclocking the percentage of heat/light changes. So which one is overdriven will tell which one is making more heat. In the case of a 1600 lumen XHP-35 vs XP-L at 900 lumens, they are both in their comfort zones and shouldn’t be getting all that hot… the boost circuit in the Klarus is probably making the heat directly from the driver.

And to establish wattage, forward voltage at the applied current needs to be known, it changes as the current changes. The XHP-35 goes up to some 14.3V when pushed at 2.5A, gotta have actual emitter Voltage at the applied amperage to know the wattage.

An example is my 18V Cree COB in the small DQG Tiny 7x XP-G2 light. At 1A the COB is pulling 21V for 2004 lumens. That would be 21 watts. Yet the small light doesn’t really get hot until quite a bit of time has gone by, so the efficiency is high and most of the wattage is burned as light out the front.

Just ordered the C8 clear from Simon and anxiously waiting for shipment. I think it’s cool people here have direct constact with sellers and can vouche for the good ones.

I was just giving a simplistic reason why one was hotter than the other for gmajnkek as he might be new here. Thanks for the info, though.

I’m curious how a C8 with xpl hi and fet driver would do against that Klarus. Probably very close in lumens and throw.

I recently did a review of the Astrolux C8, which is exactly a C8 with an XPL HI and FET driver.

Basically, it’s 1300 lumens and 100,000 candella.

That’s 640 meters.

The xhp35-HI has a 2.35mm x 2.35mm die and the xpl hi has a 1.95mm x 1.95mm die.

So if you put both these lights side by side, they should be equally bright, but the Klarus would have a slightly larger hot spot. In theory at least.

This is one of the reasons I’m glad Dale is my friend. :smiley: Him say smart stuff. :student:

Not smart, necessarily, because my memory is so bad I quite often mix information… getting it wrong. But some of the stuff sticks through sheer repetition. Lol
The efficiency issue really comes to play in a light like the Emisar D4…small quad with little thermal mass. A set of hard driven XP-G2’s put’s out a lot of heat as compared to a set of XP-L HI’s that aren’t being driven as hard.
