Direct drive 17mm driver from Fasttech

Yes there is, but it is not as bad as my Solarforce XPG, the droplets appear much smaller with the XPG drop in, so you can make your own mind up there I’m afraid.

By the way I recharged my Sanyo as it was reading 4.16v. I took it off at 4.22v and it now pulls 3.1A. Not a lot of difference but I thought I would mention it.

I think I'll drop a couple of these on my next order for testing then. Sounds like it might make a good driver for a C8-type light since it's a fairly high Low mode but can be bumped up to Turbo if needed.

Yes, The way I see it I do not want a C8 with a 200ma low. What’s the point? So 1A and 3A is perfect to me. By the way it is not last mode memory, it always comes on high. So even better!

I wondered why there is a eeprom on that driver?

Me to, now you mention it! I may even be concerned about it if I new what one was. :bigsmile:

Marc.

Does your driver has a spring on the backside?
And had it presoldered wires?

I found out that if you remove capacitor from that drives you will most likely get 1-mode driver, it will always start in high mode :slight_smile:

Also mine has no low battery function.

i changed to this driver on my cheap, underdriven xr-e c8. couldn’t stand the next mode memory, and it was very boring when it was underdriven. now it’s much more useful when it’s only 2-mode!

Used one of these in a build I like the direct drive part and then have another mode if you want it. No strobe no blinkies just good ole lumens in different doses…………. Mine pulled 1.3a on a green xre with long thin wires (was trying to be conservative) will shorten them and see if it pumps up the power.

I have played around and this little beast pushes 5A through my testleds…
I have powered it with a power supply so no voltage sag…but it got hot and smelled a bit warm.

No spring and no wires, I’m afraid. But they were already on the torch.

Marc.

It does start on high every time.

This looks exactly the same as the one in my hd2011 GK003A7

I think it must be, someone mention that earlier.

Marc.

I musnt have read that :nerd_face:

No probs, I do it all the time. :wink:

Marc.

But it’s supposed to, right?

I’m looking for a driver like this but need the low discharge protection because it’s for a family member who will be running IMR.

Fastech website says it has but coulb like chinese lumens :exmark:

Have you measured how much seconds/minutes after power off it reverts to high mode?

thanks
