Drop-in for Solarforce L2M - on CR123's

I took advantage of E1320’s tip and ordered a couple of L2m’s from Solarforce last week. I got them to give away (well, that’s what I told my wife), so now need to get a drop in that will be working with CR123 throwaway cells. I don’t think it wise to inflict recharging regimes on my friends!

So, I need to get some drop in’s. For myself, I’d prefer neutral, but for gifts, probably cool white will be more practical. I think it’s confused by the fact that the L2M comes with an extension tube, so 2xCR123 will be probably used. I’d simply keep the extension myself, and present the L2m in all it’s miniature glory, but suspect it will come in a nice blister pack, and the recipient might feel cheated if I give him a shorty,

I’ve read that the SF drop-in’s aren’t too great, so any recommendations would be appreciated.

Oh, and forget about a E1320 custom build - the first one of those I get isn’t going anywhere - it’s mine :slight_smile:

If you are going to give them out as shorties Solarforce does have one decent drop in I recommend the low voltage XPG 3 mode I have two of them, one in each vehicle powered by CR123s. They work from .8 –4.2 volts and I have had mine for over year and they haven’t burned out yet unlike the higher voltage Solarforce drop ins I keep receiving to repair.

I also started making my own low voltage drop ins using this driver since it’s so hard to find a decent drop in that will drain an Alkaline down to nothing. If your so inclined to build one yourself I highly recommend you try using this Nanjg driver. The output is adjustable via a potentiometer screw which is accessible on the back of the driver without disassembly, it can be configured to single mode for the non flashlight types who want a simple on off light plus it maintains steady output from 3.5 volts all the way down to .3 volts.

Thanks for this, E1320. Don’t think I’ll be building my own just yet (hey, I’ve just discovered “drop-ins”), but the SF tip is good - might hang onto one as a car light.

I think I would like a higher voltage option too - I can guarantee that whoever gets it will blow it if they have the extender, and will “try” 2 cells despite anything I tell them.
