What “that”? Luxeon Q?
Looks like de-doming will be either a pain or impossible. Phosphor layer covers the entire base and not just the die so it's likely bonded into the bottom of the silicone, similar to XB-D, XT-E, & MT-G2.
I think this would be nice on the triple xp noctigon in an edc host.
just need to know where to buy
You’ve made a few errors:
1.xp-g2 is 2mm2,lux Q i xp-e2 are 1mm2-big difference(to be fair compare xp-g2 with luxeon T)
2.you set Tj=25C,change that to 85C to get real comparison
3.xp-e2 R5 bin? I’ll rather stick to what is available in reality
Well I do know from personal application that XT-E will de-dome just fine if it’s any future indication with the Luxeon Q.
In the subject line I said “Nice comparison chart” and then asked in the comment section, “may I ask where that is found?” In the question, “that” applies to the comparison chart.
Thanks David, appreciate it. 
Edit: Sorry, don’t mean to be quarrelsome, the second Monday of a given week is always worse than the first.
Tbh, I never read the subject line either. So I often get confused by posts which apparently started before what I consider the start of the post :~
As far as I can tell this is competing selectively against the XP-E2 as the ‘market leading high flux 3535 LED’, but would the XP-G2 not outperform it in terms of flux whilst still being 3535 (I assume 3535 refers to the base being 3.5x3.5mm)?
Also, whilst the die size itself is more in line with the XP-E2 rather than XP-G2, the viewing angle at 135 degrees is much wider than even the XP-G2 (115) nevermind the XP-E (110). Would this not have a detrimental effect on effective surface brightness?
I’ve gotten in a bad habit of not repeating the subject line to start the comment. Why, again, do we have a subject line? Oh well. Need to find myself a Toga if I’m going to Rome.
Any idea of when these “Q’s” might be available? I really don’t see them outperforming the XP-G2, possibly the new Nichia 219B. I guess it gives us options though.
I’m glad to see some higher CRI options, we’ll see how it proves out.
Flux is not the only feature to be appreciated in a led, if you like a bit of throw you want flux combined with small die-size and this led apparently does that just a bit better than the xpe2 (xpg2 has a 2 times bigger die-size; with the same current that gives twice less throw as the xpe2)
As for the emitted angle: the dimensions of the Luxeon Q look very similar to the xpe(2), so I don' t see so much why the emitted angle would be much different, could it be that Philips just does the calculation a bit different?
I think one thing that’s getting lost here is the fact that Luxeon products have tended to have tint characteristics second only to Nichia’s 3535 products. Unlike Cree products, which tend to suffer from not having enough red, Luxeon products generally have very nicely balanced tint.
If that holds true, the most appropriate comparison won’t be Luxeon Q vs Cree XPE2/XPG2. It will be Luxeon Q high CRI vs Nichia 219B high CRI.
Does it really matter that much if emitters and stars are not readily available?
For $2.93 shipped I had a Cree XP-G2 on a 16mm star in my mailbox a week later.
We are Flashlightaholics!
It nice to know whats coming soon. Maybe put off a build if it offers a significant improvement.
If its a nice step up at similar cost the market is here & sellers will get it in. Like the original nichia219 & the new NVSL219B. As soon they can get it IS will be stocking it.
For high CRI-high color temp. freaks,wait just a little bit. Luxeon TX with 85CRI min. and 5000K is for you 
TX doesn’t seem to use the standard 3535 aka Cree XP footprint unfortunately.
I think having a standard footprint is what makes the Q interesting. Bare Luxeon chips have long been relatively easy to find, but 14-16mm round boards for them seem to be practically nonexistent.
With the Q, at least the boards will be plentiful and inexpensive.
OT: I just now figured out what '3535' and '5050' mean. D'oh. Carry on...
Good to see that Philips is still developing new product for the growing market place.
I remember back in the day, 2006, we were happy to pay photon fanatic (Fred) $30 for a U binned luxeon 20mm star that would produce 100 lumens @ 700mA.
Change is good!
Fast times at flashlight high. LED production for automotive and general lighting is taking off FAST, so should be some good times ahead with the light bulb going the way of the CRT.
I've accessed http://pct.cree.com/dt/index.html but the XP-E2 max bin displayed is R4, how did you get R5?
Oh sorry, I didn’t see the subject line, usually skip that because it is just a copy of the first line of post text…
Not quite sure, it appears that this tool is a bit quirky, now the max I see is also R4!!!
Anyways, it appears that CREE didn’t sleep all this time either:
NEW XQ-E LEDs

P.S. 1.6-mm x 1.6-mm footprint -> happy soldering
