Simon was closer than me to numbers.
I just measured the new XHP50.2 4000K L2 and got this:
1829 lumens and 49200 cd
It has more spill than XP-L HI and XM-L2 version. It lights up the surrounding area much better. Soon I will upload the video I made.
everydaysurvivalgear, have you measured the actual emitter amperage after your resistor mod to the driver? Just curious what that 9A reading you listed is doing for the emitterā¦
Convoyās my favorite. My next light will be a L2. I donāt need it, but you know how that is. I run hounds. (no animals harmed). I usually carry an S2 and a C8. I use as little light as I can to get through the woods, then a light with throw to find what theyāve treed, or at least see eyes through lots of foliage. Could somebody please explain how to choose between a L2 XHP35, XHP50.2 or XPH70.2 , or maybe something else. I want most throw and narrowest beam.
Forgive me if this is easily searchable. My old computer with dial up is a mess.
You canāt buy XHP35 or XHP70.2 L2 yet. You only can choose XP-L HI, XM-L2 and XHP50.2.
For most throw choose XP-L HI version or wait a few months because Simon want to release XHP35 HI version.
In my experience with modding the L2, the XP-L HI will give the most throw even over the XHP-35. Sufficient to say though, the XHP-35 comes close and gives more total output in the process. Significantly more light.
I have a machined finish L2 with XHP-35 HI using a prototype boost driver and it really seriously rocks. (~2300 lumens? Edit: From notes, 2246 lumens at 266.75Kcd for 1033M throw) Run time on a single high discharge 26650 is similar to what a pushed XP-L HI will draw, the extra lumens come in very handy. I also have a black L2 with extension tubes and 4 26350 cells utilizing a tweaked LED4POWER driver to run the XHP-35 at a maximum, it too does a very good job and run time is sufficient for me. I do like the short configuration of the L2 the most though and the machined finish light is just exceptional, jewelry grade. Thanks Simon!
Edit: FWIW a sliced and diced SST-40 also rocks the L2. Just sayingā¦ (careful, this one has bond wires!)
Edit: To add, a modified L2 with XHP-70.2 also impresses, just not so much in the throw department. I built one for my Bro-in-Law that he loves, something in the 7000 lumens range. Heās a hunter and uses it regularly, fights my nephew over it all the time! lol
H1-A driver makes it possible with a single cell. Available in LHT Flashlight Store and its sister shop Kaidomain. I have one running inside a super modified SK98, using additional stacked R100 + R330 + R330 sense resistors for up to ā4.20A of output current without issues (using an additional 47ĀµF output capacitor too).
Can you please give us some more information about the XHP35 HI driver?
Is it a new developed driver from your usual supplier or does it come from KD?
Will it also work 1S (1x 26650) or 2S (2x26650) only?
What is the maximum current it can apply to the XHP35 HI?
What diameter sizes of the driver can you offer?
Okay, so itās not possible to boost to 12V with only one battery. I guess Kaidomainās H1-A will still need some tuning for providing 1.5A to the XHP35HI from a single cell. But I see that Sofirn will soon launch the C8G (1x 21700 with XHP35 HI, SMO and 2.000lm). In my opinion the Convoy L2 makes much more sense with XHP35 HI. The L6 is quite a large light for this little amount of lumens (max. 2.000lm), its small reflector diameter in comparison to its length and its moderate power consumption. The XHP35 HI is - to my mind - for throwers and the L6 is more or less an allround-like flashlight but no thrower, perfect for XHP50.2 or XHP70.2. Just sayināā¦
According to Jensen567's figures the H2-C still did well at ā2Aā gear, but pay attention to the already low efficiency at that point (1S input with R075 + R075 sense resistors). Since high mode uses a 60 second stepdown you may try an R100 over the stock R050 (2.25A maximum), but beware of the low efficiency risks, high current losses in switches, springs, etc.
If I were Simon I would go to driver designers and manufacturers and tell them to āstop complaining and make an outstandingly powerful driver, this is for enthusiastsā.
