Nice!

Here’s the official announcement screenshot…
Looks like I checked Simon’s website on the right day because this announcement is super-fresh.
I mean, it’s currently 2026-01-30 in China.

I’ve been eyeing that exact setup for the past couple of months. I don’t need another light I won’t use. Or so I keep telling myself…
Thats my second one 
The first one is a testing platform
L21A that is

It seems like Simon hasn’t posted in this thread for a while.
Some people were not too happy with some aspects of Convoy lights, and there was some arguing, but I’m surprised that I haven’t noticed Simon lately.

He just put LHP73B and 20A buck combo on the market in appropriate hosts, also some new designs like M21K. He’s also moved his factory lately, so I’d assume he’s had a handfull there. Yet he still answers all of his emails …

That’s great!
Please share your impressions after testing.

Sure thing!

Do we know the binning of Simon’s 519A emitters?
5-step binned. If you are as sensitive to tint as I, then expect visible differences among adjacent emitters in the same reel.
On the other hand, the choice of optic influences tint more than sample variation. If you want rosy, choose a TIR over reflector.

Hi @Simon_Mao I see the video of Weerapat Kiatdumrong with SFT42R in 5000k and the tint aparently it’s nice. When it will be become available in your shop? I want it with the M21B.

I bought some SFT-42R 5000k from Kaidoman and installed them in an M21B to unfortunately find that it had the same green hot-spot that SFT-25R 5000k does, I hope that Simon’s bin doesn’t have the same issue but his SFT-25R bin did unfortunately.

How hard are you driving it?
10 amps, since Simon doesn’t have an 11 amp driver.

It is never a matter of cost. Who wants to risk an explosion, etc? I buy Convoys because they are the most beautiful lights. If they were more expensive to accomodate better protections, electronics, etc i would still buy them, just fewer over the same time unit.

I’m convinced that miscolored hotspots might have something to do with the oblique angles at which the LED’s phosphor throws reflects light. That in conjunction with the tint shift that might occur at higher currents.
What you explained is the cause of angular tint shift, which results in a green corona, not a green hotspot center. The latter is caused by uneven phosphor deposition, and can often be checked by projecting the image of the LED onto a white surface. For some reason, lots of recent Luminus emitters, starting with the SFT25R 5000K, seem to have this issue. Even koef3’s test sample of the cool white SFT42R has a very slight case.
And then there’s this:

Please explain - not sure I understand: why would an uneven application produces a perfect round green hotspot center? Wouldn’t it just result in an uneven colored hotspot? ie the round hotspot is there to begin with, uneven application results in uneven surface color, not creating a round colored circle.
