My first LED mod (SSC P4 with Flupic) - output stinks - need help

[Pokemonrules]

Stuff used for this project:

Mag 2C body
Hotlips C-heat sink
Arctic Alumina 2 compound epoxy
Flupic board from Goldserve
SSC P4 LED from AW http://www.candlepowerforums.com/vb/showthread.php?t=151476


Finished the modification. Works nice. There is the levels: Low, High and Max.
Otherwise works great, but output sucks!

This is my first SSC LED light so don't have any experience how bright it should be...
Or is it just so that I was waiting too much of it???



I compared this mod to my older Fenix L2T.
Compared side by side L2T is brighter than the Mag SSC P4 Mod. How can this be???
I tought that these SSC was rated some 90 lumens with 350mA. And if I have understood right the Flupic should give the LED some 1000mA on the high?

I'm now running 2 normal Alkaline C batteries in the lamp... can it be that they don't have enough Juice to run the LED. (Going to use one 18650 Li-Ion in future).

What else could be the problem?

Here is my wirings:

And here are the wirings inside:

Red +
Blue -

1. Red from switch to center of the Flupic
2. Red from Flupic (LED +) to the + leg on the LED

1. blue from switch "ground" to Flupic (LED -)
2. blue from switch "ground" to the - leg on the LED


Good advice highly appriciated.

Hello Pokemonrules

I guess that's the reason for.The batt. source should deliver the current of the vf of the Led, in this case about 3,8 Volts at 1000mA. The current from 2x C-primaries should be too low for higher driving levels.

Go with the 18650 and you will be surprised

The FLupic needs a minimum of 3x Alkaline cells the operate at full brightness.

3 Cell Alkaline minimum 4 cell max

or 1 single Li-Ion such as an 18650

Also I hope you made sure your Seoul slug was isolated.

Also maybe you should edit your title so "Output Stinks"

Thanks for your advice guys!

I will have to get a 18650 or maybe a Li-Ion "C" -cell from AW.
For the isolation I used this non elektricity conducting epoxy. Should be ok.
Would it work at all if there would be a problem with the isolation?

just to check, was the epoxy heat conductive?

because if the heat is not taken away from the LED it will cost it to heat up and output will be lowered by ALOT

secondly, 2x C cell alkaline cannot drive the led to it's minimum as alot of ppl on top of me has say.

you can either use a 18650 or a C cell li-ion .

if there was a isolating problem, the led could just go to hell in a few seconds.

I have a mag running from 1 18650 and a flupic. It it very impressive to say the least.

You should have it cut down and use one of AW protected C li-ion batteries.
