BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part IX)

Re: BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part 9)

it doesn't surprise me the Seoul version light outperforms it....:sigh:

Did you have the opportunity to compare both versions: TK-701 and the actual (i.e Cree) TK-702)?

Re: BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part 9)

Does anyone know the current capacity of the switch used in the Ultrafire 503-B? The DX MC-E module I am hosting it with draws about 2.10A (depending on the 18650 cell I use). Am I at risk of overloading the switch?

It seems OK after about ~10 cycles.

thanks in advance
:thinking:

Wow - was surfing KD and I came across an interesting 3xAAA flashy ...
ProductId=7703

For the money ?? What the heck , might make for a nice mod project ... Not much info - typical KD , but at that price , ill take my chances . It looks like it could be Cree ?? , and two mode ?? In anyway , might make a nice 5 mode Q5 mod host ... 😀

My view - Looks interesting indeed. Well, for the price at least. But it's definitely not a Cree. That's a generic LED. For that price, I guess the reflector would be plastic. Front lense is probably plastic also. No o-rings I would expect either. Looking at the beam shots, it might be a two mode though. btw, I'm more interested in that orange light which they accidently added. =P

newbie questions about romisen rc-g2 and Ma

Hi guys,

Im new here. I would really appreciate it if you could help me out a little here.

I have read several reports that the romisen draws 1600 Ma from a battery. Where does it all go before it reaches the LED? is the max for an LED not supposed to be 20Ma.

Also is there anything i can do to make tthe runtime on the romisen longer? And dont most flashilights run at 350-700 Ma? Im really confused.

P.S i ordered it from DX a few days ago so it will be a while before i get it. This is my first proper flashlight.

Oh, and how does the brightness compare to my brothers tle-5

Thanks in advance for all the help guys!😀

Sorry = More info PLZ / Model + DX item no ...

Re: BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part 9)

The ones Matt reviewed are from this ebay shop - stores.ebay.com/cwtco
Just search for RCR123A and you will find them. Cheap but non-protected.

UPDATE
- No idea why. Just out of impulse, I bought MTE SF-22 SSC P7-D-SXO 5-Mode just then.
- It looks mean and is one of the cheapest SSC P7 lights. Also is using the latest P7 D bin.
- I also ordered it as it looks like it might be able to tail stand. (Which I really like to have)
- Ordered some Ultrafire 18650's as well. (Cheapest protected 18650 - sku 19624)
- Anyways, I will do a full review when received. =)

Yeah , I got my MTE and then a few days later they get all these new models , . If only I had waited a week .

Those Ultrafires = Cheap but good , I like the two I have very much .
I got a pair of = sku.21474 , I had a fever today , so didn't get to test them .
But one of these days ....

I also got me a Charger sku.4151 , I have a very interesting mod in mind ...

Its Cheap , I hope its 2 mode , if it pumps enough mA , I might just pop a Cree P4 or a SSC P4 in there .



Hmmm what kind of LED is that ?

Re: BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part 9)

Sorry i was not more specific. The flashlight in question is a romisen rc-g2 sku 3607.

I would love to learn how to make it more efficient but i dont know how many Ma the driver is. Is this related to the battery draw?

Thanks for the help

Re: newbie questions about romisen rc-g2 and Ma

I would estimate the RC-G2 at around 40 - 50 lumens (I use a lithium primary in mine). The overall output looks similar to the TLE-5 dropin to me, but the RC-G2 throws better. I'm only going by eye, but there isn't a huge difference.

Re: BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part 9)

Thanks for the imput guys!

Can anyone explain mA or tell me how to increase efficiency?

Assuming the romisen you refered is using one AA battery like RC-A3, yes, it does pull 1600mA from the battery. Let's do the simple math from there.
1.5V * 1600mA (1.6A) = 2.4W of power is being sent to the LED thru LED driver. LED needs arround 3.7V or up, so there's a driver b/w battery and LED to step the voltage up from 1.5V to arround 3.7V. 2.4W means 0.65A or 650mA at 3.7V. LED is going to see 650mA if the driver efficiency is 100%. But you know no circuit has 100% efficiency, right? The driver itself consumes power to do the job. Typical AA driver efficiency is rather low, usually arround 50~60%. So, LED is gonna get 300~350mA at 3.7V. And, as battery drains, LED is gonna get less power, so it gets dimmed. Typically what you can expect from 1AA flashlight is about 1 hour of bright light and couple hours of dimmed light.

Re: newbie questions about romisen rc-g2 and Ma

Thank-you all very much for your help.I really appreciate it.

Just a couple more questions

will replacing the standard P2 with a Q5 or R2

a) significantly increase brightness

or

b) significantly decrease runtime

and the second is

Are eneloop rechargeable batteries the best Nimhs to use.

Re: BessieBenny's Budget LED (DX/KD etc) Flashlights Review Roundup (Part 9)

I love your reviews and am just learning. When you report throw and lightbox, what do these mean so that I may compare your ratings?

IIRC it will increase brightness by about 30% and shouldn't effect runtime significantly. Shiningbeam.com sell a Q5 version of the RC-G2.

Eneloops are one of the best LSD NiMHs (LSD = low self-discharge, meaning they hold a charge when not in use much longer than ordinary NiMHs). I use GP Recyko which are also good.

Re: newbie questions about romisen rc-g2 and Ma

Just one more quick question. HaHa. I bet u guys are fed up.

My question is

1) i just looked up creeswebsite and they say the R2 is over 100 lumens at 350 Ma. Is this real or just marketing hype.

Thanks

That's real -- manufacturers have to put real data on their datasheets, as customers will reject parts falling (more than a certain %) outside datasheet values as defective.

But lumens out of the emitter is not lumens out of the flashlight, of course; reflector and lens losses decrease the flashlights output by up to 30% or so.


BTW, it's mA, not Ma. M means mega-, m means milli-, and A means ampere, a means are (an obsolete area unit), so "350 Ma" actually refers to an area slightly larger than the state of Maryland, not to a current value...

DealExtreme TrustFire SSC P7-C Dead on Arrival!

Hi All,

I am a long time reader here, and have purchased a couple of lights (Fenix T1 and Maglite 3C LED upgrade) based on reviews here.

I just purchaesd a TrustFire SSC P7-C from Deal Extreme and it was Dead On Arrival. On installing 2 verified fully charged 18650s and powering on for the first time, it flickered for a second and then there was a burning smell and some smoke. Smells like a burned capacitor.

Has anyone else had a problem with these lights? What kind of response did you get from DealExtreme? I filed a complaint with PayPal (DOA product) and contacted DealExtreme yesterday.

What are the chances of either getting a replacement or getting my $ back?
