  • Great flood emitters at great price

    posted by yrnkrn

    These are great flood emitters at great price. The Cree XT-E are among the newest and most efficient emitters available.
    I build a rechargable emergency light with two of these and no optics. At about 10W it provides great amount of lights, as much as a 26W CFL. Maybe more. I plan to replace some CFL lights in my house with custom build XT-E and XM-L Cree lights. the cree efficiency on paper is about twice as the CFL. Practically it is less but still much better.
    Great buy.
  • nice led light

    build quality is really good!!
    i bought this as a spare...but busted my led on an inova radiant series so decided to try to put this on....started to cut the star heatsink with a wire cutter..and try if it will work...but it didn't coz its grounding the wire connection with the remaining heatsink...so decided to grind of the remaining heatsink....after that tried it and surely enough it still lit up...still a bit deep on the inova pill but nothing some copper contacts won't fix
    i definitely recommend this product....with the kind of abuse it was put under when i was working on it...it still worked...
  • It's on a par with Luxeon K2 led

    posted by Arief

    - It almost has the same lumens with Luxeon K2 led with 4.5V, 900mA, but haven't tested it with more Amps.- The hard acrylic dome lens is better compare to Luxeon which has soft dome lens (easily get dirty, hard to clean).- Very good built, and has aluminum ring around it's emitter to protect it from damage if it's not well fit from the reflector.
    It's good for replacement
    It's really a good emitter.
  • Great for an upgrade!

    Very Bright, Perfect color temperature!
    Great for upgrading your old Q3 or Q5 light!
    I purchased two of these and upgraded a Q3 and Q5 AA EDC's that I use quite often. I really liked the extra performance and the increased battery life these R5's provided. My friend also ordered one and he is over driving it with much success. One only lasted two months drivin at only 800mA but the other is still going strong at 1000mA and my friends has lasted over a month at 2000+mA which is practically triple the brightness and easily beat my P60 R5 driven at 1200mA!
  • Excellent Q/P ratio, extremly powerful

    posted by Natopsi

    Very powerful and efficient. The Insulated Metal Substrate is easy to fit on any thermal dissipation device with M3 screws.The warm white color is perfect for domestic lighting.
    If you are searching for high power LED lighting solutions this is a good choice, equivalent to a 500W incandescent light.Also, if driven at low power (5 to 10W) it has an excellent efficiency and thermal dissipation is very easy to achieve.
    I melted some plastic putting it about 1cm on the front of the led.
