【convoy】H4 and B35AM options are updated

Damn, looks like the M3 just went over the edge of one of those lights I cannot hold off from buying anymore. I had been on the fence for 2 months now every time i thought to check it out, but the charging and ramping just kicked it into my wallet. thanks… :person_facepalming:

Tanks!

Joe - not sure if this is what you were looking for.

  • The 3030's will have less lumens then their 4040 counterpart
  • The 4040's got a nice boost in amps and resulting lumens
  • The 'Boost' 4040's are considered the next generation, (3rd or 4th gen at this point), but think the majority of us were disappointed in expected throw #'s, though still better
  • Downside is the 'Boost' 4040's cost more.
  • The smaller 1mm² LED's will have a smaller hot spot, resulting in somewhat better throw, even though the amps is lower

Not meaning to be seen like a wet blanket, but the actual difference between 3030 and 4040 emitters afaik is the footprint size; the size of the interconnecting tracks is just slightly bigger for 4040s. There's nothing more.

There are no actual 4040 emitter reviews, and you may be putting too much hope. In my honest opinion a good binned 3030 would surpass a 4040 in performance, even with less current. Certain people has reported unimpressive performance from 4040s.

So wether 3030s or 4040s the most important factor imho is the bin.

I'm just going by a fairly good source for the 4040's, and that's Hank's specs on the K1 with those emitters. You are right about no BLF official tests/reviews though and bins are important, though constrained by bin availability.

I believe the K1 was previously using the 3030 emitters and recently switched to the 4040s.

It looks like Hank is still using the same driver and current (haven’t actually tested myself) so it isn’t much of an upgrade, but the 4040 package should theoretically allow heat to be sinked to the PCB more quickly and therefore allow for higher max current/lumens.

The 4040 package is about 44% larger than the 3030 so the improvement to heat transfer efficiency should be significant.

I’ve just ordered S2+ with the Green, Blue, and Red Osram emitters to join the excellent Orange-Yellow in my collection. Will do some beam shot photos when they arrive.

Post #4000!

(at the moment)

Simon, recently I saw in your store L6 host was added for sale. Is it possible to buy L6 with SBT90.2 or you will realise SBT90.2 only with new host?

The 8A driver…

Is it a buck driver or linear?

22mm 8A driver is buck, from Simon here .

Thank you, ordered one.

i got a driver ,But I have to adjust the reflector to make it adapt to sbt90.2.

So what about KW vs Ky?

So that would be white vs. yellow. As for as colors, green seems to do best while red performs at or close to the least. Yellow is somewhere in between. I don't have best or max amps #'s across the spectrum of colors - some of that info may be found here in this thread, but it does vary per color. I ordered yellow, green and red filters for the FT03 to see what it looks like. I'm no expert here, but others may know the tradeoffs between filters and real LED's.

Using my C8+ Osram W1, a red filter gives 150m max usable range from 450m. I prefer a red led.

Excellent! Looking forward to this as well as the new high CRI emitter.

Does anybody know if 219C 5700K high CRI?

So… I am quite new to all of this but I was putting a lot of credence into the 4040 camp. And I have to agree with you here, based on my experience. Here it is-
I recently ordered my first two convoys - the m21a cslpm1 and the L21a CULPM1. And although the reflector is smaller, the m21a appears to throw almost as much and be as bright as the CULPM1. Now, I don’t know how to measure lumens and throw and don’t really care to, but in real world use the 6a driver with cslpm1 really runs the 8a driver L21a CULPM1 for its money. I actually had to check them by taking out reflector because I thought they had the same emitter. I just expected the L21a to CLEARLY with bigger driver and CULPM1 to outperform the m21a. I just don’t think I’ll be buying a CULPM1 again soon for my lights. Side note- I really like bth lights and do not regret buying the L21a. It’s still awesome.

Thank you! Good to know this measurement
