【convoy】H4 and B35AM options are updated

Troubleshooting;

- Can you make a photo of the driver?

- In which light is it installed?

  • Do you have the record of where/when you bought it (I mean, the description of the product and if it was on Convoy Store or elsewhere)?

These are the first things. Then you can look into a Biscotti cheatsheet check the operation and see if it responds as it should :+1:

I bought it from here , it does have biscotti firmware. Also does the switch work with the SST40 driver running biscotti like the one found in the s21b? link

That uses one of the newer, non-7135 MOSFET linear drivers. Compatible. The S21B uses the same driver architecture. Compatible too.

This is how AMC7135 drivers look.

Someone do an overview of all of the different OSRAM emitters. I’m confused.

Check page 126 of this thread.

OSRAM LED’s for max throw

Color Part # footprint (LED surface) Max/Pulsed Peak Output (A)

White – KW CSLNM1.TG – 3030 (1mm²) W1 3/3.3 A 4.5-5.0 A (W1/NM1)
White – KW CSLPM1.TG – 3030 (2mm²) W2 5/6 A 7.0-8.0 A (W2/PM1)

White – KW CULNM1.TG – 4040 (1mm²) 3.3/4 A ~6 A (Boost HL)
White – KW CULPM1.TG – 4040 (2mm²) 6.6/8 A 9 A (Boost HX)

Red – KR CSLNM1.23 – 3030 (1mm²) W1

Blue – KB CSLNM1.14 – 3030 (1mm²) W1

Green – KP CSLNM1.F1 – 3030 (1mm²) W1 3/4 A 6.5 – 7.0 A

Thanks for that, very useful. The image especially helps boil it down.

Thanks, Tom. I was trying to find another post i had seen you link that list in, for this question but couldnt find it. Looks like the list has gotten more fulfilled since i have last seen it anyway. Good Stuff!

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.
