New 16mm Board for XML-3

Hi Guys
Pending the release of the the new XML-3, we have just received stock of our new 16mm DTP XML/XHP50 MCPCB, copper, capable of 3,6 or 12V operation

useful board to have in the toolbox for a variety of applications

Any info on these new LEDs. I’m guessing it’s nothing really exciting. Only good high performance LED released in the last few years was the SBT90.2.

Yes. The existence of the XM-L3 is likely news to most of us on the forum.

New emitters are always exciting, but I’m sure I’m not alone in having low expectations from anything new CREE is producing unless you want low CRI, floody, long runtime LEDs..

Looks like the XM remains a 3V configuration (yay). Output increase seems largely due to a new 5A max rated current. It still uses bond wires, so who knows how well it will overdrive. Efficiency is improved via much lower Vf. 5A is now only ~3.45V. Specsheet puts max output at about 1600lm @5A*3.42V (93 lm/w).

It’s an interesting looking emmiter though. Seems like a hybrid architecture. Phosphor over the bond wires and surrounding package, but still uses them (bond wires) and an elevated emitting plane.. not sure how much additional angular tint shift these will suffer due to that. You can probably forget about using old dedoming methods though. Time will tell…

Still seems to fall short of the SST-4O and possibly even good old batches of the xm-l2 with good bond wires and reasonably low Vf

The SST40 does better than the XM-L2 and the XM-L3? Odd. It’s strange they didn’t go with the flip chip like their newer emitters. XM-L2’s have trouble getting past 6A overdriven. SST40 can go well over 7A. Even the XP-L can go higher. Sounds like an emitter that doesn’t know what it is or what it wants to be when it grows up…

What does it mean for the end-(f/l)-user in terms of tint and efficiency? I have replaced XM-L with XM-L2 in all my flashlights, where applicable, and got much better tint and much more lumens (one NW XM-L2 is among my favourite LED tints despite being LCRI).

Let’s not forget one does not need a new MCPCB to use XM-L3, it works on the same pads as any other XM-L1 or XM-L2.

Am i blind? Im not seeing the specs for the LES. Anybody know what size the light emitting surface is?

Sometimes being a newb is the best part of a hobbie.

M.O.B. I mean C

Not specified, XM-L1 and XM-L2 do not have it specified either in the datasheets.

Same here. The 2-step binned XM-L2 5D4 from Simon was one of the prettiest emitters I’ve seen. In fact it was even nicer in comparison than the 95CRI FD2 SST-20 and even than the E21A 3500K.

I’m guessing this would be great for multi emitter lights like the E07 due to its low Vf?

The Vf is only low in comparison to the XM-L2/XP-L. It’s still ~100mV higher than the SST40 (djozz data). Seems like an XPL2 performance in a 5050 footprint with bond wires (aka fuses) and maybe not-so-terrible luminance and tint.

Thermal resistance is quite bad.

The only advantage I see over SST-40 is a wider range of CRIs available.
Though there was information about CRI95 SST-40 coming. Which would be interesting.

95CRI SST40 would be awesome. Don’t know why it isn’t here yet honestly. Just paint that chip with that good phosphor package Innocent

I think Cree needs something new, not a refreshed 5050 size don’t you all? Something to compete with the sbt90.2. I get high efficiency and lm/w etc, but what about power? I got sad yesterday and ordered some faithful xp-l’s.

18 of these in my MF01S would be nice

I’ve got some of these Smile
I don’t get it – what should I do to configure it working in 6v?
should I solder/jump anything?

thanks.
