No serious, if I order one it will be my first fet based driver.
I’m planning to build a convoy c8 with this driver and a XP-L HI and I’ll use a high drain 18650.
How long can I set the turbo timer? Would 60 sec be manageable? Or is 30 sec better?
It depends on your tolerance for heat, but I would go with either 120 or 180 seconds. The C8 can take a bit of heat. Make sure to copper braid the tailcap spring.
I would think that depends if you mean brighter as in lux or lumens? Lumens for the XP-L but i think the XP-G2 should out lux the HI XP-L but it could be close, if you dedome the XP-G2 it should out throw the XP-L HI more clearly i think, but this is just estimates maybe someone who have actually measured this could clear this up.
Another complication is are you planning to use it in a reflector, optic or lens light? That could also change things
Looking at djozz’sgraphs, it looks like XP-L HI should emit more lumens at the same power levels. It also makes a more consistent tint, with less of a rainbow effect going from the center to edge of the beam.
Another product similar to this, i know a lot of BLF X6 & BLF A6 buyer who don’t mod would like, is a drop in pre bypassed tail spring/switch pcb either in switch pcb through the spring style like Dale, or just a normal bypassed spring with wire or braid.
There are thousands of these lights out there now and probably only a fraction of those ever get modded, but most users can fit a pre bypassed tail spring/switchpcb for a nice lumens boost.
And the biggest benefit for you Richard, is it might be the first modding some of these users have ever done and you know when they start they will continue and buy more modding supplies from you.
I wonder if it would be possible to “build up a box to mail” over a few days and then have whatever drivers I’m lucky enough to get top that off — wait and send everything together once the “if-you-are-lucky” items are bought and paid for.
That might be way too much annoyance for the shipping folks. It might also save some postage and effort, though.
The XP-L HI will put out more lumens, but especially in the V2 bin the XP-G2 will have slightly higher intensity, although the XP-L HI is close. For throw in the Carclo optics I still think that the best is a set of dedomed XP-G2 emitters. I really should put up the 0D as a triple dedomed option because it is definitely one of the very best dedomed tints I've ever seen--I take that back; the few I have dedome are the the best dedomed tint I've ever seen.
It is possible to stack chips on the FET+1 w/A6 FW, and what would be the max amount? I’m modding a Eagletac M30LC2C and want a higher low and med modes without having to power the FET. Thanks
Will, Halo is right, you’ll also increase the level of moon because the firmware is set at a percentage of full power, so instead of a level derived from 350mA, you’ll be getting it from 700 or whatever. So all levels on the 7135 channel will increase, not just low and med.
Say we wanted 2% of max, and the chip gave us 700mA with one stacked. 255 is the maximum in the firmware, so it’d be set at a level derived for the 350mA on the original driver, which would be 2% of 350mA or a setting of 5 in the firmware. This same setting (5) will now give 14mA draw instead of 7mA, or thereabouts. This is going to bump your lumens output quite a bit, from around 14 lumens to about 50 lumens in moon. As long as you’re aware of this, then yeah, go for it.
To keep a low moon level you’d have to re-flash the mcu with a rewritten firmware to accommodate the lower requirement. Not sure how well it would work, as it’s already going to be set at 3 in the firmware, you might not have enough headroom to get a reasonable moon mode with stacked chips.
