Correct, but they have been when I tested it (residual solder on the pads).
The upper pads are S4, S3, S2, S1. The lower pads are their adjacent pads and are part of the ring. A connection would be a small vertical line connecting an upper and a lower pad. (I don't know how to paint over the picture). Is it clear now?
I received one of theese a few days ago, and now the included instructions match the mode selection table in the OP.
The instructions also advise applying thermal epoxy to avoid thermal protection kicking in prematurely. What is anyone's experience in this regard? I would rather skip that messy step...
All 7135*8 are current regulated. They are current controlled on High mode and PWM on Medium an Low. A difference, regulated - controlled. They want to say constant current.
before I got an iron w/ small tip I would do tiny stuff by stripping more of the wire, putting a little blob of solder on the end of it, putting that in place and then holding the iron onto the wire as close as i could get to the blob...
and, as for pwm - i must be the luckiest budget light guy, w/ respect to pwm - i have to try to notice it and it doesn't bother me (though, I'm sure I haven't seen the worst stuff that's out there...)
I received my set of five today and didn't waste any time.
You need steady hands for soldering on to this drop-in, it's the size of a 5p coin!
I soldered the supplied wires for the LED and soldered the points to allow for memory and Hi-Med-Low sequence.
After a little sanding of the drop-in I placed it inside a Ultrafire C8.
This is all a very much first impressions basis, however the drop-in appears to be fantastic! Low is very low, I'd call it 'near moonlight', it's actually brighter than the typical 0.2L of moonlight - very useful.
Medium is a perfect brightness. Inside a C8 body you can leave medium running until the cows come home without fear of thermal issues.
High is very bright!

PWM
Low: ?? - Unable to detect.
Med: 15.4khz
Hi: ?? - Unable to detect.
The PWM on medium is fantastic, this drop-in shows that PWM can work well. Not only is it of a high frequency but also a high duty cycle is implemented. I'm very sensitive to PWM and I'm unable to see evidence of PWM with my eyes.
Low leaves me scratching my head a little, as I'm unable to measure the PWM frequency, which is rather unusual. I'm guessing that the frequency used is too high for my testing method. As you can imagine, I can't see any signs of PWM with my eyes.
Building my first couple of drop-ins has been so much fun, I definitely recommend it to those that haven't done so.
I now have a neutral tinted (T6-3C) C8 and a cool white (T6 1A) C8 with will spaced modes, no flashes, moonlight mode with crazy runtimes and I am able to use all 3 modes without the annoying strobing affects of poorly implemented PWM, the likes of which is found in so many budget lights/drop-ins.
I plan to write up a more in depth write up soon, but this is all for now. :)
I am absolutely with you on that one. I really have to work hard to notice any modest PWM. Besides, I think my hands are shakier than what the average PWM will produce (and they're really not that shaky) so it's a moot point anyway! haha
