Ultrafire Cree LED WF-606A

I put a DX 16mm Q5 in mine, the output is noticeably better. Unfortunately they only sell the WC tint which is bluer than I prefer.

I just got this one which is the Q2 version and have the Q5 version on order, maybe hoping to swap out the emitter and switch. But I must have hit the DX jackpot. This light is bright, whereas most people are measuring 800 or so mA, mine on a fully charged set of energizer 2500's are going at a strong 1200 mA. It has great regulation because a set of half discharged nimh's will pull 2000 mA. Though I'm only getting about 1.5 hours runtime on a set of batteries, I know these are a true 2500 mAh because I have a battery charger/discharger that tells me the capacity of the cells.

Did I mention how bright this is? It put's my inova bolt to shame, ironically my multimeter is from walmart and is of the innova brand, two n's. Does get kinda hot though after 15 minutes of continuous burn time.

With a Q5 I'm impressed at how close it gets to 18650 torches in performance.
I don't use it much nowdays as I joined the Lithium-ion fold.

I measured the same runtime with new Q2 WF-606A, it looks like they use different driver than they used a year ago.

Does anyone know if any dx drop in module's fit this light? Ironically enough I wanted to do heat tests and removed the emitter to put heat sink epoxy, screwed down too tight and shorted the bulb, so the whole regulator is burned out.

I just purchased the WF606A Q5 from Deal Extreme.

The WF-606A uses a Cree XRE Q5.

Fit is excellent. I give the grade A.

Finish is excellent. I give the grade A.

The Cree Q5 module screws out very easy. It's different from the earlier WF-606A's.






This version uses a Cree XRE Q5.





The modules comes out very easy.











I also took lux readings of the WF-606A Q5. These are the lux readings I got. I am using a Meterman LM631 Light Meter measured at 1 meter. I waited 2 minutes before taking the readings. I am using Energizer 2500mAh Nimh AA Rechargeable Batteries which were fully charged.

I've measured runtime of the Q2 version. It is significantly shorter than P4 version I had a year ago.

That doesn't look so good.

It would be nice to see a run time of the WF-606A Q5.

Sorry I don't have Q5 version.

I just got the Q5 version from DX last week. Theyve changed alot since I bought the Q2 version 6 months ago. Before the change the tailcap and forward clicky from a ROMISEN RC-G2 would fit perfectly on the 606a. Now with the new q5 version theyve changed the threads on the light so it no longer fits. Doesnt seem to be as well made as the older version. Anodizing is more of a matte finish now. The pills will interchange though. So I took the q5 out of the newer version and put it in my older version with the forward clicky.

Did a quick runtime test with the Q2 and Q5 at the same time. Both ran for an hour with no drop in brightness. At 1.5 hours both had dropped to about 60% brightness. I dont remember the exact voltage but the Q2 lights batteries were about gone where the Q5 lights batteries still had plenty of voltage left.
As far as brightness goes for the first hour the Q5 was only a little brighter than the Q2. Both lights get really warm after 20 min. Not HOT, but close. I used DURACELL ULTRA BATTERIES.

I bought a natural one of these back when it first came out. It's been fantastic, we use it all around the house for a couple years now.

My only complaints is the button that is oversensitive, and there is questionable waterproofing because the lens is undersized.

I felt like this was one of the best flashlights I bought directly from China.

My button was also sensitive to the touch and all i did was cut a sliver off the nipple of the rubber boot.

Ha! I also cut a sliver off the little nipple on the boot. I also sprayed some wd-40 in the plastic switch assembly just to make sure it doesn't corrode and to protect against water intrusion.

Here is the WF-606B version, FWIW. With the CR2 cell. Ignore Malkoff M60 next to it.

I got my switch loosened up to an acceptable level a long time ago. I honestly forgot what it took, maybe oiling the nub, removing the tit or stretching the boot. :shrug:

Hey nice light etc. Do you like it? :naughty:

P.S. that threaded tail allows you to put it on a standard tripod.

It's a neat backup piece, with CR2.

I'm a Correctional Officer at a juvenile work camp in the mountains. I carry the Q5 version as a less-bright backup to my CL1H. It works great for cell searches or indoor use without being overbearing. The switch is sensitive, but I like that is quick and precise. It's a great replacement for the mini-mag.

anyone disassemble the switch on the q5 version?
I cant seem to get it open...

This is how to take out the rear switch. BTW this is the Q5 version.



I like to use either a pick or pointed neddle nose pliers.



There are 2 holes located in the circular nut.



If it's very hard to turn the circular nut I like to use the pointed neddle nose pliers.



If it's easy to remove like my rear switch was I'd rather use a pick. It's faster for me to use the pick.



Turn counter-clockwise.



The switch comes out very easy.



Reverse the order to install.
