Ultrafire Cree LED WF-606A

[ernsanada]

I just received the Ultrafire Cree LED WF-606A from Kai Domain.

https://www.kaidomain.com/WEBUI/ProductDetail.aspx?TranID=2255

Shipping took 16 days.

Uses Cree P4.

Can be used as a 2AA or CR2 size light.

1 stage reverse clickie.

Come with a lanyard.

Fit and finish is excellent.

Type II Anodize has some flaws in the finish.

Costs $20.42.

CR2 Size

Cree module screws out very easy!

In the following beam shots the Energizer 2300mAh Rechargeable AA's were used in the Ultrafire Cree LED WF-606A and the Jet Beam CL-E.

The Lumapower M1 Cree used a Tenergy 18650 Li-Ion Rechargeable Battery.

I think if you are interested in an inexpensive 2AA Cree light this might be a light for you.

The Ultrafire Cree LED WF-606A has a nice beam and nice tint.

I am going to use this light at work. I lost my Mag Led 2AA so I think this light will be a good replacement.

+1 from me...

I intend to replace my MinimagLED in my camera bag...One of my cameras runs on CR2s so the choice was obvious. I had been waiting for more than a year for buying in hope something better came out and presto! Cree version!

Also this is a great gift flashlight. It runs on AA and has a clickie!

enjoy & thanks ernsanda, kostas

If runtime is not too bad, I might get one too.

 

[ernsanada]

There is a natural version of this light.

What is the current draw when using the two nimh AA cells?

What is the current draw when using the two nimh AA cells?

2.12V

 

[ernsanada]

Current draw on AW's Protected RCR2 is 3.38V.

In the Stepped down exposure the Ultrafire Cree LED WF-606A, AW's Protected RCR2 looks a little brighter.

i use sanyo eneloop.

Wow! The Ultrafire Cree LED WF-606A, AW's Protected RCR2 is a little pocket rocket!

2.12V

thanks, but actually I was talking about how much current in milliamps the light draws from two nimhs. This will determine roughly what the runtime will be.

What's the best way to measure milliamps?

 

[nanotech17]

unfortunately my sanyo 2700mah too fat for the battery tube.
Ernsanada,
The AW rcr2 - is it 3.0v or 3.7v?

Ernsanada - You'll need a digital multimeter (often referred to as a DMM). A DMM will measure voltage and current; volts and amps. They are available at Radio Shack (and many other places) for not alot of money, and are invaluable to the flashaholic, especially one who does excellent reviews/pics!

For example: for this light, let's say you find the current draw to be 800ma (milliamps). If you're using 2500ma capacity nimh AAs, you can figure you'll be getting fairly close to 3 hours runtime (3 x 800ma = 2400ma). And as nimh cell voltage discharge is fairly flat, you know you'll be getting decent output "regulation" in addition to whatever the circuit is doing.

I do have a DMM.

Where do I measure on the light to take the current draw?

----------------------------------------------------------------------

Where do I set the rotarty knob?

 

[__philippe]

Set switch on position 10A A DC (Amperes / Direct Current)
Plug probes in "COM" and "10A" connectors

Cheers,

Configure the meter like filippe said, then take the tailcap off of the light. With batteries installed in the light, place the meter's black lead on the negative end of the battery, and then touch the red lead to a bare area at the tail of the light...right at the end of the body tube, or on the threads...wherever you can find a good ground point. When doing current measurements, the DMM acts as the light's switch, completing the path from the battery/ies negative to the light's body.

Using the 10A scale of your meter, say you get a measurement of .73 or something like that. This means .73 amp, or 730 mA. Have fun!

 

[LGCubana]

Using an AW 3.7v, 350mAh (RCR2)
.832 - .838 mAh

Maxell Gold, CR2
.690 - .695

Depending on my point of contact on the rim of the base.
