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!

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.

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.

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.

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

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

Does anybody know if 219C 5700K high CRI?

Here it is- I recently ordered my first two convoys – the m21a cslpm1 and the L21a CULPM1.

What about tints? I been thinking of getting CULP, but still not sure if I like that color. Its a bit more warmer vs. cslp?

Hi I recently got the L21a osram and I absolutely love that thing!
When I turned it on for the first time the hotspot was very off centred. The hotspot had no corona on one side but three cones on the other side. I tried to readjust the reflector but nothing helped until I jammed a tiny piece of wood (the end of a toothpick) between the emitter and the cantering ring. Is this normal?

When I modded my M21C to CULPM1 I had to put a shim between the bezel and front glass. The 4040 centering ring is quite a bit thinner than the 3535 or 5050 variants which caused the reflector to sit very loosely in the head. I wonder if L21A has a similar issue?

Simon you did a great store tune. 
It is much more easier to navigate.

This is great. Hope it it will be available in M21C-U or L21A.

Yes, what are your plans for those puppies?

The Osram leds are so small which makes them extremely hard to center 100%. Most other brands, if not all, have off center Osram leds. I find it’s the mcpcb that tightens down with screws that throws it off center.

The L21A is for long range anyway, so very doubtful you’d every notice outside, only on a white wall
