ultrafire C8 with a CREE MCE (1000 lm?) (? 4, 4wat LEDs?)

[TURNER936]

I bought this Cree MC-E six inch powered by one 3.7v 2200mah. It was advertised to push out 1000 lumens. Don't get me wrong, this is a tremendously powerful light for under $90 with three rechargeables and shipping. It destroys all Coast (and others you can find at high-end walk in retailers. I just don't believe it throws 1000. It may hit 500 to 600. does anyone know about this light. I did a bit of research and there are three MC-E four cluster leds bulbs that look identical except for their peak lumen output. I stopped building flashlights a year ago and this link :

:thinking:


is helpful if you want learn about all the bulbs in one place. you can buy there . high end quad layout LEDS are only about $15. the chinese retailers , however will negotiate and you can end up with two for $15.
SORRY ABOUT THE RANT. This is my fist post and I never even thought to find a forum. I thought i was the only person who collected and I will probably always buy the next best thing. I told my girl i will stop collecting when i find the perfect light. -I flick it on and the beam feels like i just fired a 12 gauge.
one last thing since I'm ranting; any excellent reflectors to look at?

Sorry, but that light is probably only putting out 400 or so lumen's.

There are two main 4 Die LED's on the market. The Cree MC-E, and the Seoul Semi Conductor P7.

Neither is capable of producing 1000 lumen's.

No, a single MCE won't give you 1000 lumens. And be aware of UltraFire's flashlights have general problem with heat management. Their batteries are like lottery as well. You may get good ones if you are lucky. Otherewise they won't work after 2 or 3 charges.

ElectroLumens EDC MC-E puts out about 700 lumens,
The fenix TK30 and TK40 put out 630 lumens.

The MC-E is a really nice emitter, my guess is
400 to 600 lumens is the norm.

Electrolumens light is high on the scale because it's directdrive, single mode.

Cree lists the MC-E at 700 lumens at 2.8A.

Most single cell lights run at 2A (to control heat and provide better runtime).
So 700*2/2.8=500 lumens.

Now the reflector/lens absorb some of the light. Transmission varies from 65% of a Mag to 81% for a Fenix. Let us use 75% for the Ultrafire (glass lens instead of plastic of the Mag, no AR coating like the Fenix).
500*0.75=375 lumens.

For reference a 3W MagLED is ~50 lumens, a Rebel MagLED is ~100 lumens.
So the Ultrafire is ~4X as bright but not 1000 lumens.
