This probably isn’t the best place to ask, but since David bumped what turned out to be an interesting, somewhat related thread:
Is there a list anywhere of 4-channel drivers? Here’s what I know of so far:
- Mountain Electronics has one that has been around for a while.
- tterev3 used to offer the really sophisticated looking meld-x, but has discontinued it.
- Dr. Jones also used to have a similarly neat looking e-switch driver, but it also appears to no longer be available.
- The Light Saber driver also looks awesome, but is too big for most flashlights, and not yet available?
My personal interest is RGBA, specifically an E17A quad from Clemence, to put in preferably an S2+ with a frosted lens.
I can probably live with the driver Mountain offers, which is easy because it comes assembled, ready to go, for a decent price, and the default current is a good match for the E17A. The drawbacks are the modes are fairly basic, switching mode groups requires soldering, output is only adjustable by swapping resistors, and there’s no mode that runs all 4 channels at the same time - the color E17A’s are phosphor converted, so they should be able to mix to a pretty good white, if you get the power levels right.
