    What's the next step up from an XHP70?

    I'm looking for a LED that will put out around 7-10K lumens for some custom off road lights (more like work lights than driving lights) I'd like a 12v diode because I'll be using a linear driver. Is the Cree CXA series what I want?

    Connecting multiple MOSFETs for extreme current switch

    I used an inductive ignition coil clamp. Again, I have no idea if I set it up correctly or if the clamp and scope are even compatible with each other (the clamp is Fluke, the scope is Snap-on) And Roger that on the safety glasses!

    Connecting multiple MOSFETs for extreme current switch

    I'm not sure if I measured it correctly, but I think the motor generated 350V of kickback under no load. From this I'd imagine I'd be around several kV when switching off a high load.

    Connecting multiple MOSFETs for extreme current switch

    I just heard from them: I guess I'll try to parallel a couple of the smaller mosfets and see what happens. I can't imagine it would exceed 100A reeling cable out :shrug:

    Connecting multiple MOSFETs for extreme current switch

    I emailed their technical support about the power required for letting cable out under load, I'll see if they provide anything helpful. I do have access to a oscilloscope, I'll see what kind of inductive kick I'm actually dealing with and report back.

    Connecting multiple MOSFETs for extreme current switch

    If an H-bridge was used, could I use two of those mosfets that you linked in you previous post, and two of the smaller ones that I already have? I assume reeling the cable in requires FAR more power than letting it out.

    Connecting multiple MOSFETs for extreme current switch

    Ok, thanks. Like I said, it will have some pretty significant cooling capacity. And about the inductive kick, the issue I have is the motor needs to be able to swap polarity in order to real the cable in or out. Is a ~15V bidirectional TVS diode what I need?

    Connecting multiple MOSFETs for extreme current switch

    Ohhh, that could work! I have 20 of the TO-220 mosfets already that were for a different project, but maybe it's not worth the hassle. The inductive kick was the next issue I was needing to address, but I wanted to see if anyone could help with mounting first. EDIT: I see it says max power...

    Connecting multiple MOSFETs for extreme current switch

    I'm trying to setup a solid-state switching device for my coworkers truck winch. The manual says it can draw a maximum of 335A at full load. I was planning to use 8 TO-220 mosfets that are rated at 49A each. They will be connected to the A/C evaporator line, so heat shouldn't be an issue. I'm...

    TK75vnQ - Best Searchlight

    I have a question about heat! I assume the driver in the XHP70 version is a linear type. Would a extended run tome kit raise or lower the operating temperature of the driver?

    30 amp single battery Vinh light using Sony VTC5?

    The VTC5 is not rated for 30A continuous discharge

    I think 3 and 1would be better! The MM18vn has plenty of throw, imo. But MOAR lumens! Maybe even 3 xhp70s and 1 xhp35? :naughty:

    I'll try to take some comparisons tonight of my xhp70 version vs. my Mercedes' D2R HID lights EDIT: Sorry folks, something came up tonight. I'll get pictures tomorrow evening.

    WTS: LD50vn ;-)

    Yes it certainly could be done. But the U4 Dedome shifts to a very green color. The reflector in the LD50 has a tendency to make things a little green as well. Combine the two and I think you will end up with a very bright light with an unbearably ugly tint.
