how many lumens, is this a true cree xml-t6

I don't have a lumen tester, but it seems much brighter than your normal led light. I'm a cable guy and looking under homes or in the attic, this piece will light it up for sure, and it won't hurt your eyes as some do. I was very happy with it till I lost it after the 2nd week. The clip is not reliable. It bends way to easy. It came off my belt and I know someone out there is happy to have it. Hope that helps. It's worth the money.

The claims of the # of lumens are all over the chart. Therefore not too reliable. You can see the valve at the bottom of a 5 ft 4" black pipe as bright as day with this little jewel. Best lite that I have ever owned. Well worth the $.

It is as advertized. I bought 4 different and this was the best. Batteries last 30 min of continuous use. I use it on a bike and recharge often.

The Cree claims '10 yr life', based on 3 hrs per day. A much better indicator is total run-time. Then do the math, depending on how you will use it (... maybe it's 4hrs per day ...).Cree makes several different levels of efficiency. Not all Cree is the same quality.They tend to over-hype their products.Feit has been a reliable company, with good quality electrical components, for many years.The bulbs are instant-on and work with most older, existing dimmers. So take a chance on something different, than Cree.

So far, been running (6) of them for over 6 months (normal at-home hours) and no failures. I also prefer the Cree brand but could not find them in a Par 16 fixture. Brightness is very good and they are dimmable. (must install a LED approved dimmable switch for best results though)

I didn't use it with Cree.What I use with this dimmer is a dimmable A19 LED light from Triangle Bulbs and it's working well for me for 2 years now. I like the light output because it's beautiful. It's also durable. Triangle Bulbs T95123-6 (6pack) - LED Dimmable 60 Watt Equivalent Daylight A19 Light Bulbs, 6 pack

Incandescent bulbs produce about 16 lumens per watt, so you want 3x60x16 = 2880 lumens. This reel (looks as if they changed the description since you asked this) produces 40% of that, 1180 lumens, or about as much as one 75 watt incandescent.The HitLights high density reel produces 2x light, costs 2.8x.

It doesn't really matter, why are you asking since the LED needs no servicing and Cree LEDs are now only a slight bit higher efficiency, not enough to matter on a value priced light.

If you have three modes Low,High and strobe, you have the real thing UltraFire WF502B CREE T6 XM-L 1000 Lumens . If you have five modes it is a cheap copy and dim display. I have bought 3 and got the right one twice E-cloud and prettylight and a fake from SunnyStore8 with a LED array 1/4 the size of the real one.

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

It should be noted that "lumen" can mean many things depending on how you obtain a lumen measurement. At one foot away with the "zoom" at max spread the light produced 4800~4900 lux which is about 450 lumens/sq ft. Though when focus to a point the light produced over 90,000 lux which is about 8,300 lumens/sq ft. Unless you can find definitive data that explains the lumen of this light (or any other light in existence) the advertised brightness of a flashlight is meaningless. It's would be better to look up the datasheet for the Cree XML emitter and search for visual examples of the light (using quality 3.7V 18650 Li-Ion bats of course).

The product description says that these are 72 lumen total. The LEDs are 3528 SMDs which output 6 lumens a piece. If you're planning on building a flashlight, my advice would be to use a Luxeon or CREE LED instead; these tiny SMDs just don't put out enough light per square inch. On the plus side, they're dirt cheap, so if you're on a budget then this is probably a good choice.

I will say No but the NEW P7.2 does have a CREE LED, The Lenser Website call's it Upgraded to Cree LED - P-7 is 170 lumens and the P7.2 is 320 Lumens - Almost Double, Looks like I need to upgrade myself

The generic Amazon listing which is what I used to list mine says 500, but I bought it from the Surefire website and it says 600 lumens. So I would imagine that the website is accurate.

if it is the newer one with the Cree XM-L2 and not the XM-L U2 then the rating will be 2900 lumens. the opposite is true about the 2600 lumen rating. as of right now, the most likely one is the older, 2600 lumen model.

Cree Led Bulb R5 3.7-18V 500 Lumens for Surefire Flashlight Torch C2 G2 Z2 P60 P61 6P 9P G3 S3 D2I just found this on the Beck Tek (no relation) website. It advertises as made for the C2.

According to this spec sheet from the manufacturer, the T6 and U2 are both under the same Cool White model. Definitely not a knock-off. Just a varient within the same Cree group. http://www.cree.com/~/media/files/cree/led%20components%20and%20modules/xlamp/data%20and%20binning/xlampxml.pdf

I do not know the true output i have no way to test but if your worried if the light is not bright don't worry. I have had mine for 8 months now use it on a daily basis is very bright the testing I have seen done on this shows that this light is truly 800+ lumens and I believe it. It's a great deal at 40 bucks I recommend buying 18650 battery and charger I have gone on to buy 3 other lights from thrunite I am very impressed with them all considering I use to work at a outdoor store and sold surefire Phoenix lights and other high end lights. Buy it you won't be disappointed.

I believe it is approx. 2304 lumens , hope this helps! Don't get hung up on the wattage of a led fixture but more important is how many lumens per watt , the better quality like Cree are setting the standards!
