I ordered an Ultrafire C2 flashlight after reading Ernest Sanada’s great review on CandlePower Forums, but delivery from DealExtreme.com in Hong Kong took 5 weeks. They have good prices, but you can’t expect your stuff right away.BatteryJunction.com (highly recommended) – they only took 4 days for delivery.The Ultrafire C2 uses a Cree XR-E-7090 P4 LED which puts out up to 87.4 lumens @ 350 mA, according to Cree. What this actually means is this flashlight is really bright. The manufacturer also says, “White XLamp LEDs are tested for luminous flux and placed into luminous-flux groups.” Your flashaholic calls it binning -they test the LEDs, then throw them into “bins” depending on their output. These Ultrafire C2s use a P4 bin LED.type III specification – it’s gray. The Battery Junction Ultrafire uses the type II specification anodizing – it’s black.A couple of days ago, DealExtreme came out with an Ultrafire C2 that uses the Cree XRE-7090 Q5 LED, which has a maximum luminous flux of 114 lumens @ 350 mA. What this actually means is this is really, really bright. I ordered two Cree XR-E Q5‘s on star boards from Kaidomain.com, maybe I can stick one in one of my C2s.
