Ah, ok. So I guess they typically don’t fit a Quad XP-G2 optic? So perhaps the XP-G3 is the safer bet.

The teardown pics looked like XM-L2’s in the stock light? Or are those G2’s?

If G2’s then yeah I would just go with the G3’s and be done with it.

The issue is finding a local source for them. Cutter has them and there are a few local places that offers them as well, just not in a very wide range of tints and bins.

Or the XP-L HI. The HI version throws basically the same as an XP-G2 with less tint shift around the edges if your lens has an issue with that.

They’re XP-G2’s.

Good to know. Guess I wouldn’t have any issue with the optic resting over the XP-L HI’s would I? Hmm . . . or would I? Seems I would as there is no dome to rest the optic on. The legs of the optic don’t touch anything, just go down through the openings around the pcb. I’d probably just go XP-G3 anyway.

Cree, Inc. has introduced a new high-efficacy (HE) edition of the XLamp XP-G2 LED, a progression that the company claims yields greater output and higher efficiency than its predecessors.

The new XP-G2 is optically compatible with the original XP-G – providing drop-in-ready performance enhancements to shorten the LED fixture design cycle and improve time to market. A new high-efficacy option is available, as well. The High Efficacy XP-G2 LED leverages Cree’s latest high-power chip technology to deliver 25% more light output via a higher maximum current of 2000 mA, higher efficacy and lower thermal resistance. Combining high light output, reliability and efficacy, XP-G2 is optimized for directional, high-lumen applications

I know these are relatively new out but does anyone know of supplier with stock?

Xp-G2 S4 HE 180Lumens @ 350ma XPGBWT-BE-0000-00L50

More importantly can this new emitter knock the XP-G2 S4 2B of its pedestal for king of the throwers??

It has been dethroned. Comparison table here.

Wow!! good god!! dethroned , its been lane waste, thank you so much for answering I have spent days reading posts and asking questions on CPF all to no avail first post I make on here an i have an answer , so the Osram KW CULNM1.TG is now the king for a super tightly focused thrower presumably the 1mm version? do you still dedome them or jut buy the flat version?

Been looking to upgrade a nigthmaster Xsearcher with a new driver/emitter combo & crelant 7g5cs this should be just the ticket

The only place to buy the KW CULNM1.TG is at led4power.com. The bare leds are out of stock, but he still has 2 reflowed on a 20mm MCPCB, and 4 on a 16mm MCPCB. Not sure when or even if he will get them in stock again.

These are very low voltage leds so even if you want them at 5A you need to regulate the current or they die from overcurrent. For output/voltage information see the OP of this thread: http://budgetlightforum.com/node/63255 . The KW CULNM1.TG is the last one discussed in the OP, you need some scrolling.

First... I like to think of this forum as a bit more helpful than the other forum Wink Thumbs Up 

The White Flats are already domeless (or "flat-dome"?). The CULNM1.TG is a 1mm2 version with 4040 footprint, but is already discontinued by Osram. Led4Power got a limited quantity but it currently says only two remain. However, it looks like the other two (CSLNM, 1mm2 on 3030 footprint, and CSLPM, 2mm2 on 3030 footprint) are still available, and they are nearly as good - still better than XP-G21. Do pay attention to the low Vf of these emitters and the recommended current to run them at - they turn angry blue on simple FET drivers with halfway decent cells.

 

1: This gets complicated with a Wavien Collar, as the XP-G2 gains more from collars than white flats.

It is A LOT more helpful, I have literally spent days trying to ascertain what the best possible upgrade i could drop into these units would be , wasted money on bad advice and was not really any closer to an answer , it seems most people like to just buy something off the shelf and hope the manufacturer tells the truth about its specifications and parts used.

Bit confused by these numbers

the XPGBWT-BE-0000-00L50 (2amp) lists
Minimum Luminous Flux (lm)
@ 350 mA = 180Lumen with a max current of 2000ma which is 5.7×350=2amps / 1026 lumens.

Looking at the chart above i have to run 6 amps into the KW CULNM1-TG to get 1023 lumens

What am i missing here?

Edit: (penny drops)
even if i only run 2 amps into the CULNM1-TG it will still give higher FC than the g2 because of that die size, its a have your cake and eat it situation and doesn’t have to come at the cost of run time….. I had it in my head i was going to have to Run 6amps into it to get the same performance as 2amps on S4 in reality for the same 2amps il get way more lux / fc I didnt realise the S4 was being over driven

Sorry guys im very new to this!

This forum Rocks!

Yes, luckily they can.
Same footprint.
