FAQ about Cree LED Flashlight

Difference between lux and lumens? Hey everyone. I've been wanting to purchase a flash light. I'm a bit confused though. So far all the flash lights I have taken a look at measure their brightness in lumens, like this one for example: http://www.dealextreme.com/p/ultrafire-u4-mcu-cree-q5-wc-3-mode-230-lumen-led-versatile-flashlight-cr123a-18650-18500-aaa-17401 And this other flash light I found has a different measurement. I don't understand it. http://www.dealtoworld.com/reviews-12479-50767-Bright+flushlight.html The output is 85 lumen...? This flash light is a lot better than the first one, so I'm a bit confused. Could someone please explain me how this stuff works? Also, if you have any idea how much lumens the second flash light might be, please let me know. Thanks everyone. From Wikipedia
Lux versus lumen
The difference between the lux and the lumen is that the lux takes into account the area over which the luminous flux is spread. A flux of 1,000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1,000 lux. However, the same 1,000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux.
Achieving an illuminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12,000 lumens. To light a factory floor with dozens of times the area of the kitchen would require dozens of such fixtures. Thus, lighting a larger area to the same level of lux requires a greater number of lumens

Is this a good bright flashlight for camping? CREE Q5 LED 260 Lumen Flashlight Lamp Torch UltraBright Im in BSA and been in it for bout 2-3 years now. Im looking for a better flashlight. The CREE Q5 LED 260 Lumen Flashlight Lamp Torch UltraBright is made by "Surefire" (as it says). Please help! You certainly picked a bright light. One problem with such a bright light is that it will not last long. In some of the specs I saw it would run for 4 hours on the battery. That should be enough for one night out. If you are out two nights you may run out of power.
I have not used the Surefire brand. It certainly is expensive at $ 50.
I personally prefer a headlamp. With a headlamp I can work with both hands. I will use a headlamp even when I am not camping.
I would recommend two flashlights One would be a 30 lumen or less headlamp for around camp. The second would be a 90 lumen or more light, for emergency travel at night, or just for high power.
It is good to take a medium power flashlight camping. If you need to head home in the middle of the night because of an emergency. You do not want to use a small pen light that does show things in your path, or the lack of them like a cliff. The web site below recommends 30 lumens about 1 watt, for walking on a trail. Tactical / military lights start at 90 lumens or 3 watts. Yours is very bright at 260 lumens. That explains the short battery life. You need a light that will last till you get back to the trail head, while traveling at night.
Maglight makes good LED flashlights. I have a 4 D - cell battery 3 watt Maglight. I tested it an it ran for 27 hours on alkaline batteries. They also make a 2 and a 3 D-cell flashlights with a 3 watt LED bulb. LED is the way to go, it lasts 10 times longer. The Maglight is less expensive than the CREE Q5. Maglight has good quality. Brinkman also makes good flashlights
I have had bad luck with Princeton brand and Gerber brand of flashlights.
Enjoy your camping.

Is this flashlight worth $151? I saw this flashlight on a b2c website(here the link:http://www.dinodirect.com/wolf-eyes-fox-i-digital-cree-r2-ho-285lumens-led-rechargeable-flashlight/s-94.html),it cost 151$ Here is the question:how much would you guys spend for this flashlight? Oh. wows. not worth it. >< you can buy any other flashlight and it might work just fine for you. I would probably spend $10-20for this flashlight. =/ it just look the same as the others to me.

Any ideas for a good flashlight? I am looking for a very good flashlight. One that is relatively small but very bright. Must have the push button on the end and must be black. Can spend about $60 for this, so I want the best for the money. Right now I am looking at a Smith & Wesson M&P Tactical CREE LED Flashlight. If you have any helpful input on this question, it would be greatly appreciated. Thank you http://www.fenixtactical.com/fenix-ld40.html
Fenix LD40, 10 bucks more than your target price and a much more versatile design. Also it uses 4x AA batteries that are easier to obtain (and cheaper) than the CR123 batteries the S&W light uses.

Best flashlight for me? I want a flashlight that has a far throw and has to be led.I have narrowed it down to these three choices, http://bestofferbuy.com/Aurora-AK-P7-5-SSC-P7-C-8-Mode-Memory-900-Lumen-LED-Flashlight-with-Assault-Crown-(1*18650)-p-14154.html?currency=USD&utm_source=gbase&utm_medium=cse&utm_campaign=gbase , http://www.dealextreme.com/p/ultrafire-wf-502b-ssc-p7-bin-c-5-mode-800-lumen-led-flashlight-1-18650-39737 . http://www.dealextreme.com/p/aurora-wf-800-q5-1-mode-cree-led-flashlight-7-4v-17v-8686 I'm sorry but I didn't check your links...I've been boned too many times for checking unknown links...
I've recently purchased a Mini Maglite that is a 2 "AA" cell LED flashlight. I've been very happy with this flashlight. It has the rugged dependability that made Maglite famous, and the brightness out of the 2 "AA" batteries rivals that of my traditional 4 "D" cell Maglite.
The one feature that SOLD me on this flashlight was the use of "AA" batteries. I've had LED flashlights in the past that require fancy lithium camera batteries that are extra pricey and hard to find....not a fan. You can go to just about any convenience store and pick up some AA's though.

LED Flashlight Question? Hi I have a Flashlight with a Cree Q5 LED bulb and it supports .7V-4.2V and I was wondering if it would be brighter if I put a rechargeable Li-ion 14500 battery. Right now I'm just running regular Duracell AA with 1.5V. Would It be brighter if I bought the 14500 batteries? What brand should I get if I wanted to purchase the 14500's? The flashlight is advertised at 230 lumens but it only uses one AA so I dont think It can reach 230. But if I buy the 14500 would that maximize the light output? Thank You If the driver can handle it, it should be significantly brighter.

How do I source this LED driver board? I have purchased several of this type of driver board from dealers on the web. But I am getting tired of paying retail price for them. I want to know where to purchase a bulk lot of this type of driver? How do I source this board? The board I am looking for uses a 7135 chipset and is multimode with a high of 2.8 amp. This link has a picture of what they look like. http://cgi.ebay.com/LED-Driver-Circuit-Board-for-Cree-MC-E-SSC-P7-Emitter_W0QQitemZ250594211855QQcmdZViewItemQQptZUS_Flashlights?hash=item3a5894380f The ones I want have the 8x 7135 chips on them, and use the Atmel TINY13V controller chip, but I would prefer the board that has the 4 stars on the back to program the driver rather than the 17 mode like this one. Its likely that these come from Hong Kong, but I am not certain. The 10 points goes to the one who finds me the manufacturer and/or the cheapest bulk lot of them.

Why is this thing only $17? Its 500 Lumen flash light off ebay from a United States seller? Tell me what you think about this. At a sams club they selling a 200lumen for $29.. this is a 500 for $17 http://cgi.ebay.com/CREE-LED-Lamp-500-Lumens-Flashlight-Torch-14500-Charger-/280621693020?pt=US_Flashlights&hash=item41565b385c Maybe but see they are selling 10 of them More than likely its a chinese piece of crap. It will work for 2-3 minutes and then break. Regardless of "location" or "ship from" address, 99% of stuff on ebay is chinese knockoffs and they aren't worth anything

EDC flashlights? or favorite flashlights? I never see any flashlight questions on the hunting section... (besides the dude wanting to mount a light to his shotgun). Whats your favored flashlight? If you would have asked me this a good few months ago i would have said my standard AA mini mag light. But Here last month we went through a period where snow knocked out our power for a good 2-3 days, while the maglights kept working they were pissing me off because i had to change the stupid light bulbs or they just werent lighting up enough. So i did some research and studied away and saw guys were really like these new Cree LED lights. I looked at SureFire and saw what people had to say but from what i picked up, while they are good lights they just arent worth the money and guys were talking about Fenix and 4Sevens as coming up to being serious competition for Surefire. I went and picked up a Fenix LD20 and ive got to say. It is well worth the money and now im curious why i never looked at these types of flashlights before. Its my first investment in a flashlight but im happy and hell its bright enough i would use it for night hunting out to a good 100 you can see there eyes and im sure it would give you a positive Id on what they are out at about 40-50 yards. So whats your favorite flashlight? Oh wow, I am a flashlight maniac! I am not fooling when I say that I own about 50 different flashlights; everything from the little keychain LED lights that can fit into a breast pocket of a shirt, up to the 6 cell Mag Instrument lights.
These days, the absolute best value that I have found are the Coleman 115 lumen LED lights that sell for about $25 at most big box retailers. These things really put out the light and are small and compact enough that they can fit into your coat pocket. The battery life in them is pretty good and the bulbs are supposed to last a lifetime.

Which flashlight should I pick and which batteries to go with it? I'm trying to find a flashlight and batteries to go with it for when I go camping. I'm just looking for something strong that will light up paths in the forest. I have found two sets of flashlights/batteries that may be suitable for me but since I have never chosen a flashlight and do not know much about batteries/flashlights, I'm looking for some help, Thanks! Set 1: Flashlight: http://www.dealextreme.com/p/trustfire-r5-a3-cree-xp-e-r5-3-mode-230-lumen-memory-led-flashlight-1-aa-1-14500-39062 Battery: http://www.dealextreme.com/p/trustfire-protected-14500-3-7v-900mah-lithium-batteries-2-pack-blue-19626 Charger:http://www.dealextreme.com/p/trustfire-tr-001-multi-purpose-lithium-battery-charger-12594 Set 2: Flashlight: http://www.dealextreme.com/p/torch-light-c78-flood-to-throw-zooming-cree-q3-wc-130-lumen-led-flashlight-1-aa-29095 Battery: http://www.dealextreme.com/p/soshine-aa-2500mah-batteries-4-pack-487 Charger: I don't know which charger will work with these batteries. I am open to any suggestions for batteries/flashlights, or tips on how to pick them. Also: my budget is about $20-$30 total. Thanks! -Sunny edit: Are rechargeable batteries the way to go? Or just any disposable batteries are alright.
