【convoy】H4 and B35AM options are updated

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

yes, 90CRI

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.

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

I saw that Simon has just listed the L21a in ‘3v xhp50.2 6500k’.

Could someone school me on all the different led options available for the L21a?

So far the only ones I’m familiar with are the SST40 and Osram.

What are the bullet point differences between

- 3v xhp50.2

- xhp35 hi

  • xhp70.2?

Throw xhp35 hi > 3v xhp50.2 > xhp70.2
Lumens goes the opposite way. Probably along with battery drain if that matters to you.
xhp70.2 is a beast, expect it to be big and bright but not carry as far.
Xhp35 is the only de-domed one which makes it throw better (+ the fact that its smaller and that generally = more candela) the 4000k is super pleasant of you’re into warmer (possibly higher CRI) tints. It’s also discontinued, what ever that means in this hobby anyway:P

Hello Simon,

I just would like to ask, if you have access to either XHP35 HI or the new XHP35.2 HI (introduced in March 2020) emitters.

Basically, the XHP35.2 HI has very similar performance stats to the older XHP35 HI, but I think, at some time point, XHP35 HI will be more difficult to access, and XHP35.2 will be better available.

The most important question is, can you get 90 CRI tints of either the old XHP35 HI, or the new XHP35.2 HI, and if so, what CCTs you can access at your Cree retailer?

YES!!!^^^^^^^
I’m on XHP35 (.2) 90CRI humt for some time. Prefferend tint is 4500K and 5000K.

Mouser and Digikey have them but minimum order is 500-1000pcs :(

Simon, any update on your SBT90.2 Light? Approximate Release Date? Host release date?

I’m pretty sure these (XHP35 HI 4000k B4-40E) are 90 CRI. I have some and they’re really lovely.
