Rebel LED (3D version) Under/Overdrive

[mansell2]

I bought a new version MAG 3D with Rebel reflector and emmitter for my SST-50 Mod.

After removing the switch assy which I won't be using in my build, I considered where I could put to use.

I used an old 2d host and fitted it with the new 3D LED assy. I used the old style reflector. you have to remove the old style cam. Then remove the cam screw and LED pill. Then drill a new cam hole 90 degrees from cam slot. Drill the new cam hole as close to end of plastic as possible. Stretch the LED pill spring and re install at a higher fixed position.

On 2D alkaline it produced a smaller / dimmer (but still white) beam. Pill does not appear to have any boost capability. Pill was marked "U3"

I sleeved 3 C sized alkalines and modified the spring to seat inside the cap (de anodize required) and 3 alkalines returned the beam to its as purchased beam intensity.

Then I thought 2x18650. Some quick math inticated 3x1.5 = 4.5volts 2 x 4 = 8 volts. But hey why not give it a go? I sleeved the 18650's and turned on the light.

I received a bright beam for 1/4 sec and .


I returned to lower voltages to check for life :thinking: but my led was dead :sick2:.

interesting experiment?

i'm pretty sure 3 alkalines would experience voltage sag under load. why not a single 18650?

why not a single 18650?

Because you weren't there last night to ask me then .

2x18650 was an easy attempt given my setup. Too late to try it now. Maybe next time....or another member can give it a go.

The question is, what did you ? More than likely the circuit board. You can probably separate the module and put the can with the Rebel LED to use with a good, working lower half. I believe that Mag now pots their boards into the plastic lower half unlike the earlier MagLEDs that I have so taking it apart would be extremely difficult.

I was just playing Lego with my Rebel pills this morning. I put a 3D Rebel pill into a Mini-MagLEd and admired the near moon-mode that I got from two NiMH AA cells. Then it occured to me that I have three near new N cells sitting around never to be used again so I rolled up some paper and made a sleeve to hold the 3N cells and dropped a short piece of aluminum rod on top of the last battery before I screwed on the tail cap. Now I have a nice little 3N Mini-MagLED until these batteries run out of juice.

Yeah, I would have gone with one 18650 and a spacer.
