Which bulb for a 2D mag with 3C's

I have a 2D Mag i put 3C's.. alks at the moment.. the stock 2 cell bulb is much brighter and a nice white rather then the ugly yellow but i figured i would ask which bulb would give me the most light output?

I am rather tight on cash so i am stuck with what i have for the moment so no battery holders or that sort of thing at the moment that cant be easily home made


is the 3cell bulb brighter then the 2cell overdriven? and will it be as nice a color?

thanks again!

I'm running a KPR103 3.6V bulb in mine. I tried several times running the stock Mag 2 cell bulb but it consistantly poofed. Someone said that the 2 cell bulbs don't hold up well on 3 cells because they're being driven at 150%, whereas a 3 cell bulb on 4 cells is only being driven at 133%.

The 3.6 bulb isn't the greatest choice but it does give you 3 cell performance in a 2 cell light.

Now, a 3 cell being run on 4 c cells will overdrive nicely and produce a white light. But that being said my 3 cell 2 D light is pretty white.

Probably didn't help much but at least you have an answer.

yah i have not poofed mine yet so i guess i will just let it go till it dies then maybe i will have the cash for the battery adapters to go 6 or 8 aa's in it.


anyone know if the KD ones are any good on his site it says on high amp applications high resistance is a problem... i assume it would be easy enough to fix by changing contacts right?

Another option is to watch for a sale and buy a Mag-Led drop-in for 3 cells. I might be trying that one myself.

The classic answer is the XPR103

But I have found the Japanese H-26P the brightest 3-cell PR bulb

Gotta a source for them? I bought out all the remaining stock in 3 separate Radio Shacks locally.

Again, somewhere on here, someone posted a "fix" for the KD 3 to 1 cell adaptors. I think it did involve changing or beefing up the contact points, with, I believe, extra copper. It was in a thread about the ROP and the poster provided pictures showing the before and after.

A better choice is either Fivemega's or Mdocod's adaptor. The FM has the advantage of being able to charge all the cells as a whole pack. Mdocod's adaptor is very affordable.
