How much better is XP-G Cree?

[LEDrock]

I guess the specs are out there somewhere, even though the LEDs themselves aren't. I've heard about them on this board recently, but I just tried doing a search for XPG and XP-G and got no results.

Here's my question: If a Fenix LD20 with a Cree Q5can put out 180 lumens using 2AA batteries, how many lumens can we expect if that same flashlight were upgraded to a Cree XP-G?

I heard 37% at 1 amp.
I hope someone does a group buy!!!!!!!!!!!!!!

Are they expected to be really expensive?

If the LD20 is 180 lumens out the front, then the same setup with a XP-G R4 maybe around 240-250 lumens.

Wondering if the XP-G can handle being driven at 1.2A or more with good heat sinking. We could probably see 300 OTF lumens if it can handle it. It's supposed to be around 340+ emitter lumens at 1A.

They are available in the limited Titaium Quarks, XP-G R4's. I think the 1st round of the pre-order is over, but you maybe able to still get in on one, or more. :)

Based on the price of the lights they can't be that much more expensive than the XP-E's, etc.

Cutter has them for preorder.Stock arrives 25sept. But still does not mention exact binning and tint. I emailed him for details.

LD20 is 180 lumens from the emitter, not OTF.

Anyone making a XP-G Cree 18650 light?

My WAG is at least half of CPF is waiting for such a light to hit the market :twothumbs

+1 i have been keeping this( http://www.candlepowerforums.com/vb/showthread.php?t=230446 )thread open on my comp all the time hitting refresh each time i walk by.

just thinking about DD'ing 3 of these with a pwm controller and a 18650 in a 6p..1000 lumens OTF!!!FTW!!!


I NEED NOW!!!!!

Thanks for the clarification. I put that "If" in there for a reason. :) So then the XP-G would be around 240-250 emitter lumens, maybe. :P

Most manufacturers wants to charge us 3x or 4x the current flashlight price when using a new emitter or titanium material.

The new upcoming quarks have both titanium and new XPG, while keeping a very nice selling price of less than $100. Other manufacturers would price a product like this at least $200. So, xpg or titanium it is not really that expensive, they just want to take advantage of excited flashaholics when new products are being released.

+1. Waiting for a beamshot comprision between Cree XPG and Cree Q5/R2.

Agreed. David at 4 Sevens likes to show that top quality is available for a lot less than some of the other mass manufacturers charge (I'm not comparing him to custom but instead some of the other truer comparables). I'm really looking forward to a Ti XP-G Quark as well as his upcoming MCE light.

Am I correct in saying that the physical dimensions of the XP-G die are larger than those of the XR-E?

Yes.

Dude i love you!

We know you have a XP-G and the dancing banana tells me that you have not only over-driven the XP-G but that the results where good enough to make you dance like a banana. and you only have the R3, i bet that the R4 will do even better because of the less heat that it makes.

Time to bust out the IMR'S WOOT.:party:

ok its 1 AM and i need to stop thinking about flashlights i won't have for at least 2 months. night all.

Q:
How much better is XP-G Cree?

A:
Maybe

:thinking:

Fenix LD20 Q5_________,__2 Alkaline AA_________high_________163.2,____3 sec_______,
Fenix LD20 Q5_________,__2 Alkaline AA_________high_________158.5,___30 sec_______,
Fenix LD20 Q5_________,__2 Alkaline AA_________high_________157.9,___60 sec_______

So now that we know LD20 is putting that OTF, how many lumens can we expect if that same flashlight was upgraded to a Cree XP-G?
