Kind of strange the other yezl lights have 3 mode w/o blink and this is 5.
I just checked, it,s still unshipped. That's a very bad service. If it,s still unshipped tomorrow, I will cancel it.
So how are we going Ric on that postage? Have you sent them yet?
It's more like either aspheric or reflector. If you use both, the reflector will only result in a quite ugly spill pattern.
Hm, does look interesting. Maybe the red is a bit more forgiving :) I've seen uglier images, e.g. here.
Here's my favorite, one of the worst things you can do in that respect, MCE with OP reflector and aspheric :)
The light that is caught by the reflector only gives that outer ugly spill, it does not contribute to the spot at all.
Well, it's still unshipped. I decided to give them a last chance. I used their message form and I made them some kind of an ultimatum.
Edit:
I just saw I have got a private message from Ric. Apparently it is shipped now, but the the info on my account was not yet updated.
Ric answered via email. Those Yezl T9 orders will be shipped tomorrow with tracking number. They already have been packed. It is 2200hrs HK time now.
Very interesting Ric-CN. I'll be ordering this shortly.
Ric-CN,
30USD sent at time of posting for one Yezl T9.
Any news Ric? Also sent you an email the other day.
Anyone else heard anything recently about these?
I got my tracking number for the T9 yesterday and it will be on a plane today. Most likely packing and also shipping yours out. :beer:

Hmmm, is an XM-L (125°) really suited for flood-to-throw lights? Especially in throw position a lot of light is lost by hitting the side walls instead of the lens. OK, I can see how this light will be useful in flood position, I love the beams on my C78 and UF H2B. The beam angle of the XR-E (90°) is more suited to flood-to-throw lights, though.
Hi Rec,
I want to buy 1xT9+1xbattery charger+2x 18650 batteries if possible.
If it is OK for you, can you give price and shipping informaiton.
I want to use T9 with my bike, is it possible to use it with my bike ?
Thanks

Yes, you are correct. I have too many throwy lights. I got this for (1) Shelf queen, big head darth vader looks (2) Flood.
Some lights like UF U-80 can flood, but the spot is extremely ugly. Only my Xeno E03 XM-L is flood, but it cannot flood powerfully for long. For flood you'd need power. I have 2 x 65W HIDs when operated in flood mode can flood a few blocks of apartments 100m away. That's really cool.
The XR-E with it's high dome as sort of pre-collimator does have an advantage in that respect, i.e. it catches more light. However, that does not increase the throw, only the size of the spot.
The XM-L T6 @3A has (with all other things kept equal) 37% less emittance ("surface brightness") than the XR-E ez900 R2 @1A, which gives ~19% less throw, regarding only the emittance.
However the bigger die size helps overcome lens aberrations, so it might be a bit better than that.
Guessing a "relative throwiness" factor of 10000 and an effective lens diameter of 40 mm, I expect something around 400m throw, i.e. 40kcd spot intensity - not bad :)
Can't wait to receive that light and do actual measurements...
Edit: Uh, someone posted that that light is under-driven @1.5A? That'll reduce throw...
I think surface brightness isn't that important with collimator lenses, it's more important that the light actually "hits" the lens and not the walls. Also the lens has to be calculated for the according beam angle.
This is just to show the difference between 125° (62,5°) and 90° (45°) beam angle.
So you roughly need twice the lens diameter for an XM-L compared to an XR-E to "catch" all the light. Pull out is ~31mm (not counting the distance in flood position) so the lens would have to be at least 2x1.92x31mm=119mm ... lol...
I think a TIR-collimator-combo would be perfect for this type of light.
You guys are thinking too much. If you want optimisation its gotta be for a 300K lux @ 1m project like the LED torpedo of ma_sha. This Yezl T9 is a Darth Vader design light, which also happens to be a close to 3A driven XM-L so you get more or less enough lumens and usable in the real world with the good even flood (ie no hotspot, like that Dereelight NOHS). 
Try something like a 1.2kW SFC-10-4 bulb with 7mm arc gap and a 24" reflector - that is throw. That is 110,000 lumens over 7mm, or 157`4 lm/mm. You can't even sqeeze this much out of 15k lumens from an exotic 6-XML maglite. Think 0.6 deg beam. Should hit 100M lux. They go up to 10kW (or 15kW I heard) but pretty big gaps...IIRC 34mm.
Carbon arcs do 2 billion. Enough said. H i g h I n t e n s i t y D i s c h a r g e .
Want more, it'd be lasers, nothing else. They can do like 400,000 km throw for practical reasons.
Ok ok, just joking brothers....don't flame me.
OK, where can I get those in an ITP A3 host configuration with no heat issues and runtimes of at least 4 hours on an Eneloop AAA ? Full moon on.... full moon off... ;-)
Actually its like HiFi / DIY Audio. Use the correct tools. HiFi drivers got their uses, Pro Audio is another usage. 
I like my Single Ended Triode amps, headphones etc. But I also like my DSL DTS-10 and TH-112. (for bassnuts - car audio has as much as 30-40dB cabin gain)

Vectrex: Well, it may sound funny, but throw does NOT depend on the aperture angle (i.e. how much of the flux is caught by the lens). I mainly depends on two factors: lens diameter an LED luminance ("surface brightness"). I gathered some info on throw here, mainly for reflector based lights, but they share the basics.
The more flux ("lumens") you catch with the same diameter, the bigger the hotspot gets (which of course is a good thing, too), but neither intensity nor throw increase.
A 30mm diameter lens with a focal length of 25cm (and 25cm distance) will catch only a tiny fraction of the LEDs flux.
A high-NA lens with 30mm diameter and 20mm bfl (and 20mm distance to the LED) will catch much more light. However it will have not more throw, but a much bigger (and more useful) spot.
