UltraFire WF-501B SSC-P7-CSXO

[tuli]

Hi all, I purchased this flashlight for $20.68 thinking its a SSC-P7 and what could be the difference at all.

It is very bright for a $20 light, but not as bright as the more expensive ones - $30-35.

Can anyone help and explain why?

Is there anything I can do to increase the output?

Thanks!

From the sounds of people's comments on the DX P7 drop-in, the driver isn't drawing enough current. Therefore you would need a new 17mm driver (circuit board) and solder it in place of the one the flashlight came with. Of course if you drive a P7 at 2.8 amps to get the full brightness you will also get a lot of heat (you'll need some good heatsinking) and there won't be much battery life.

I know Shiningbeam.com had a well regarded driver board for P7's at one time, but it doesn't seem to be in stock right now and therefore doesn't appear on their website. I've never messed around with P7 drivers, so you may have to ask around if there are any good ones from DX or KD, if you're willing to do some soldering.

:welcome:

Thanks a lot man!

i'll check around to see if any recomended one is available.

off course it only worth a little money to invest or better to leave it as is and to buy another flashlight...

thanks for the welcome!

The original driver is pathetic. I swapped this one with KD 5 mode direct driver for P7. However, the tailcap current draw is still only 1.8 A. They probably used high vf P7 bin. Don't know about the others, but the beam quality on my example is not on the prettiest side.

+1 for the KD driver...adn rush cos it is on the sales list.....
ProductId=1845

and I think that the performance is also determined by the batt too...(in high mod it works in Direct drive)

Hi,

i posted a reply earlier but i don't see it.

i'll look into replacing the driver although I never did it before.

i guess i'll look for some instructions for the firs time.

Thanks for your help and welcome :thumbsup:

I purchased sku 36030 drop in. I received one with a red driver and it pulled 2.5a high and .2a low. Memory was wonderful, however, it was a pathetic build really. It had a huge donut hole, lots of rings, and no where near 900, or even 600 lumens for that matter. It was probably around 300. It was floody, though.

vF , voltage forward ... C***I bin VS say C***J bin

The I bin will have lower vF and run harder , the J bin will run around 2A or lower depending on the battery driver combo [ 18650 ] .

No joy with the J bin in single 18650 applications , swapping drivers may result in a small gain only .

Hi,

I'm not sure I understand. It saise CSXO not C***I or C***J.

Are you saying messing with replacing the driver wil not help much?

Thanks!

 

[old4570]

Yeah , they left out the part [ letter ] that tells you the vF .

If its a J-bin [ higher vF ] then your gains from replacing the driver may be very small , if you have a Multi meter , best to check current draw @ the tail end to see just where you are , if its very low , 1.6A or less , then a driver swap may be your only option , but expecting more than 2A , maybe not . It could happen ? :shrug:

thanks man, i'll check and see

has anyone tried doing a direct drive on this light with the p7?
