Cree bins individual models of LED on the basis of total flux or light output, typically measured at 350mA. Bin numbers might be P4, Q2, Q3, Q4, Q5, R2, R3, R4, and R5 with each bin being about 5% additional flux. The P4 is 80 lumens, a Q5 would be 107 lumens, and the R5 bins are 137 lumens. At higher amperage than 350mA, the brightness goes way up, with the XP-G producing 3 times as many lumens at a maximum current of 1500mA.
Cree bins individual models of LED on the basis of total flux or light output. Individual flux bins are about 7% apart taken at some reference current like 350mA or 750mA, but at higher currents the output goes up, up to some maximum current. Cree measures output at a reference temperature 85° Celsius, which is a more realistic operating temperature, but in the past they measured at 25°. Output is typically higher at a lower temperature.


Cree classifies tints generally as being warm, neutral, and cool, but has recently added "outdoor white" in between and overlapping neutral and cool (4000-5300K). Tints are binned using a system based on the [[ANSI White]] standard. Cree's tints subdivide and expand on the ANSI regions giving bins such as cool 1B, neutral 5B1, and warm 7D2, though many other tints and subdivisions are available. Click on the graphic at right to see all of the bins, though not all bins are available.

In addition, Cree produces High [[Terminology#CRI|CRI]] LED's, with CRI values of 80, 85, and 90 represented by bins H1, P1, and U1 respectively (separately, L1 represents normal CRI white LED's, and O1 is outdoor white).

==MC-E==
Below are output numbers for different currents for the various brightness bins of more current LED models. There is more information available with the '''[http://pct.cree.com/ Cree Product Characterization Tool]''', an online calculator that allows you to look up output based on more factors. The numbers on this page, like those given by the PCT, are based on charts in the LED datasheets.


A 4-die LED available with four of the same color dies or the MC-E Color with four different color dies (white, red, green, blue). The maximum current is 700mA with a Vf of 3.4V, though this varies from one color to another. Bins run from G (240 lumens) to M (430 lumens) at 350 mA. The white quadrant of the MC-E Color is available in cool white (A5) or neutral white (A4).
'''Older models of Cree LEDs have been moved [[Old Cree LEDs|here]].''' For bins at 25° see [[Cree 25 degree bins|this page]].

==MT-G2==


The MC-E was widely used in high-power flashlights like the EagleTac M2SC4, Fenix TK40, iTP A6 Polestar, and JETBeam M1X with advertised output of up to 700 lumens. The color version is in the Quark RGB (with neutral white or cool white available) but although the LED allows mixing of colors, the Quark RGB is switched to one color at a time.
Large die high power LED has versions that run at 6, 9, or 36 volts with maximum power of 18 watts, first available around November 2012. The LED is 8.9mm x 8.9mm and the light will be floody compared to the smaller XM-L. The first production lights to use this LED were the Crelant 7G10 and Solarforce S200, introduced in May 2013. The LED is binned at 85°C. The bins shown below have been increased by 15% to give output at 25°C for easier comparison to other LEDs.

==XB-D==
==XM-L2==


Very compact LED (the die is mounted on a chip 2.45 mm square opposed to 3.45 mm square for XP series) introduced in February 2012, promising lower cost. Should provide similar brightness to XP-E LED's. First available units were warm white with Q2 brightness bin (at 350mA). This LED is binned at an operating temperature of 85&deg;&nbsp;C instead of 25&deg;, so in order to directly compare its output to other LED's that are typically binned at 25 degrees, the numbers in the table below have been increased by 14% (see [[XB-D output]] for the 85&deg; numbers). Can be driven up to 1000mA. [http://www.cree.com/products/pdf/XLampXB-D.pdf Datasheet], [http://www.cree.com/news-and-events/cree-news/press-releases/2012/january/120111-xbd press release].
Same 5mm x 5mm size as the [[Old Cree LEDs#XM-L|original XM-L]] but with up to 20% more output. Introduced in December 2012. Like the XP-G2, the XM-L2 is silver on top, has two bonding wires, and the die has dots instead of lines. The XM-L2 is significantly larger than the XP-G2 and has a round hole at the upper left as opposed to the XP-G2's square hole. The first production lights to feature the XM-L2 were the [[ThruNite]] Catapult V3 and TN31 in January 2013, followed by a number of Xeno lights which also had options for neutral tints in Feburary.

==XM-L==
[[File:Creexm-l2.jpg|thumb|right|Cree XM-L2 is the same size as the original XM-L, but a new design]]
 
[[File:Cree-xml.jpg|thumb|Cree XM-L LED with 6 yellow strips and 3 brass bonding wires]]Larger die LED first available in November 2011, offering efficacy of 160 lumens per watt at 350mA. Output is 260-280 lumens at 700mA (bins T5 and T6) therefore it is more efficient and puts out more light at any current than earlier single-die Cree LED's. However the biggest improvement to overall output is the XM-L can be driven to 3000mA for 910-975 lumens of output. The LED die is 2mm x 2mm on a 5mm x 5mm substrate with 6 yellow strips and 3 bonding wires as opposed to the XP-G with 4 strips and 2 bonding wires and the XP-E with 3 strips and 2 bonding wires. The first production lights to feature the XM-L were versions of the [[ThruNite]] Catapult V2 (first to ship), [[EagleTac]] M3C4, a [[4Sevens]] Quark MiNi, and the [[JETBeam]] M1xm, introduced in December 2010, but budget retailer KaiDomain had LED's and [[P60]] drop-ins as well as P60 lights around the same time. Neutral and warm tints began shipping in March 2011.

==XP-C==
==XP-E2==
 
[[File:Cree-xpc.jpg|thumb|Cree XP-C LED has a smaller die than the XP-E]]A lower current version of the XP-E with a smaller die. Maximum current 500mA and Vf of 3.5V. Bins up to Q4 (100 lumens) in cool white, Q2 in neutral white (84.7 lumens) and P3 in warm white (73.9 lumens). Looks like the XP-E, but the die has 2 yellow strips and 1 bonding wire instead of 3 strips and 2 bonding wires. The XP-C is used in the Streamlight Microstream.
 
[http://www.cree.com/products/pdf/XLampXP-C.pdf Cree XP-C datasheet]<br clear="all">
 
==XP-E==
 
Introduced in Fall of 2008, the XP-E shrunk the XR-E by 80% (though it uses the same die), now 3.45 mm square. It is available, in white (cool, neutral, and warm), blue, green, amber, red, and red-orange. For cool white, bins are Q3, Q4, Q5, R2 and R3 with output from 93.9 to 122 lumens. Neutral white bins are from P4 to Q4 (100 lumens min) and warm white bins range from P2 to Q2 (87.4 lumens min).
 
[http://www.cree.com/products/pdf/XLampXP-E.pdf Cree XP-E datasheet]
 
This LED is used in the [[NiteCore]] Defender Infinity, early Quarks (R2, neutral whites used a Q3), the iTP A series EOS and S series lights, EagleTac P100 and T100 series.


The XP-E has 3 strips on the die as opposed to 2 on the XP-C and 4 on the XP-G.
Introduced in September 2012, this redesign is similar to the XP-G2. Cree claims up to 20% more output than the [[Old Cree LEDs#XP-E|original XP-E]] at half the cost in terms of lumens per dollar. Given the small die size, this LED throws well for the amount of output. It was used in some smaller Fenix flashlights.

==XP-G==


Same size package as the XP-E, but with a larger die. Therefore the resulting beam has a little more flood. It is available in varying output bins from R2 to S3. Maximum current is 1500mA and Vf of 3.3V with efficacy of 141 lumens per watt. [http://www.cree.com/products/pdf/XLampXP-G.pdf Cree XP-G datasheet], [http://www.cree.com/news-and-events/cree-news/press-releases/2009/september/090930-xp-g-led press release].
==XP-G2==


The XP-G R5 began widespread use in 2010 after being adopted early by 4Sevens and EagleTac. The limited edition titanium Quarks were among the first to use the XP-G, with an R4 bin. S2 bins became available in November 2010 but only in Quark and iTP special edition lights. Special edition matte-finish titanium Quark Mini and Turbo models were the first to feature S3 bins, shipping in December 2010.
Introduced in July 2012, the XP-G2 is an all new design with the same size as the [[Old Cree LEDs#XP-G|earlier XP-G]]. In August 2012, [[Foursevens]] was the first company to adopt this LED, claiming up to 20% more output and a 5% smaller hotspot for greater throw compared to the same models using a XP-G.

==XP-G2==
==XP-G3==


Introduced in July 2012, the XP-G2 is an all new design with the same size as the earlier XP-G. Like Cree's other 2012offerings, the XP-G2 is binned at 85&deg;C, but for ease of comparison, output is increased by 13% to get 25&deg; values. [http://www.cree.com/news-and-events/cree-news/press-releases/2012/july/xpg2-intro Press release], [http://www.cree.com/led-components-and-modules/products/xlamp/discrete-directional/~/media/Files/Cree/LED%20Components%20and%20Modules/XLamp/Data%20and%20Binning/XLampXPG2.pdf Datasheet]
Announced in April 2016, the XP-G3 is completely covered in yellow phosphor and can be driven to higher currents than the XP-G2, with a maximum current of 2 amps instead of 1.5. High CRI versions of the LED appear to be available in all tints, even cool tints.

==XR-C==
Same size as XR-E (7mm x 9mm) but is designed for less current (500mA max). The die itself is smaller than the XR-E (same as the one in the XP-C). The maximum bin is Q2 with 87.4 lumens for cool white. It is available in white (cool, neutral, and warm) as well as royal blue, blue, green, amber, red-orange, and red. Vf is 3.5 volts at 350mA. Identifiable by the metal ring around the dome and a LED die with only two yellow strips and one bonding wire.
[http://www.cree.com/products/pdf/XLampXR-C.pdf Cree XR-C datasheet]
The XR-C is used in retail lights made by Coleman, River Rock, and Energizer.
==XR-E==
[[File:Cree_xr-e.jpg|thumb|Cree XR-E LED easily identified by the metal ring around the LED]]Introduced in the Fall of 2006 the XR-E was widely used in a number of different flashlights, with cool white, neutral white, and warm white colors available in addition to blue, royal blue, and green. Common bin numbers are P4, Q2, Q3, Q4, Q5, and R2 with increasing output from 80 lumens to 122 lumens at 350 mA and a Vf of 3.3V, but with much greater output available with higher currents. The size is 7 mm x 9 mm and you will often see this referred to as a 7090 XR-E. The die itself was available as the EZ1000 at first and then the smaller EZ900. Because the EZ900 can have the same overall output as the larger EZ1000 but in a smaller form, it should provide 23% greater intensity and throw (the EZ1000 is 1 mm square and the EZ900 is 0.9 mm square).
[http://www.cree.com/products/pdf/XLamp7090XR-E.pdf Cree XR-E datasheet]


This LED was very widely used, featured in flashlights by [[Fenix]], [[JETBeam]], [[NiteCore]] D10, and [[EagleTac]] P20 and T20 series, and is still available in some [[budget lights]]. The neutral white version is used in Nitecore EZ series. It is easily recognized by the metal ring around the die with 3 yellow strips and 2 bonding wires.<br clear="all">
==XP-L==


==XT-E==
[[File:Xp-l.jpg|thumb|Cree XP-L HD LED puts a large die in a XP-G size package under a frosted dome]]
[[File:Cree-xpl-hi.jpg|thumb|Cree XP-L HI does away with the dome, allowing greater throw]] Introduced in May 2014, the XP-L puts the same size die as the XM-L2 onto the smaller 3.5mm board of the XP-G (shaving off the edges of the dome to make it fit). Due to the larger die, it will not throw quite as well as the smaller die of the XP-G, but it puts out more light and can be driven at higher currents. Binned at a higher current than the XM-L2, higher bins are typical for the XP-L, but a V5 bin XP-L is roughly equivalent in output to a U2 bin XM-L2. In June 2015, Cree began shipping a "[http://cree.com/LED-Components-and-Modules/Products/XLamp/Discrete-Directional/XLamp-XPL-HI high intensity]" or "HI" version of the LED with a flat coating instead of a dome that could offer the throw of a de-domed LED without the trouble. The original domed version is referred to as "high density" or "HD." The brightness bins for both are the same, but the highest bin on the HI is about V3.


[[File:Cree-xte.jpg|thumb|Cree XT-E LED]]Introduced in February 2012, the XT-E has the same size chip as the XP series but seems to have a wider viewing angle for more flood and less throw. Can be driven up to 1.5A and available in bins up to R5 (at 350mA). This LED is binned at an operating temperature of 85&deg;&nbsp;C instead of 25&deg;, so in order to directly compare its output to other LED's that are typically binned at 25 degrees, the numbers in the table below have been increased by 14% (see [[XT-E output]] for the 85&deg; numbers). Cree introduced the XT-E as a low-cost, high efficiency LED capable of 148 lumens per watt at 350mA, offering higher lumens per dollar. The LED is not a flat square, but has an X shaped hill on the surface. The beam is like a small XM-L with a large hotspot and some varying tint across the beam. [[EagleTac]] was the first company to feature the XT-E in a production light, making it an option in the D25 clicky series in April 2012. At about the same time, KaiDomain offered P60 drop-ins and flashlights with the XT-E.
