I thought Ti comes from USSR or Russia nowadays?
No, it's all China. Any Ti coming out of any other nation, was first imported there from China.I thought Ti comes from USSR or Russia nowadays?
I managed to twist the head off of mine, as described, can see the back of the PCB with spring. PCB has two holes which suggests using a spanner to rotate to remove it. I tried needle-nose pliers which usually works. It does not want to come off and I prefer to not damage it; suggestions?Pull the head as far upwards as it will go like you're zooming in.
The keep pulling upwards while turning the head and it should unscrew and you will see the pill as soon as you get it off.
If it's on super tight you may have to turn it very hard and fast at the same time. Most it's not that hard usually.
Best of luck. Just remember it's the zoom feature that makes it tough to get the light apart. Pull it to full zoom and turn it really quick and like you mean it. Once you get it off you will see it the pill it's screwed into and it's turning as your turning.

I want to see what's inside even if I can't fix it. There is no made in U.S. restriction in my case. I have learned a lot by opening things up, even which are not broken, including how to re-assemble things.Sure.
Put it back together, put it on the shelf, and FUHGETABOUTIT!!
Dave,The driver PCB is press-fit and separate from the LED "star" (aluminum). I was able to pop out the driver board with small slot screwdriver. Driver IC is a tiny 3-pin device, not much else other than four 1-ohm current-setting resistors and capacitors (no diodes). I verified that LED at least lights, by probing with DMM set on "ohms" or diode-test, causes a dim glow. Failure mode points to the IC.
IC pseudo-marking is GW05 which I don't know has been identified, even so it is likely
not easily obtainable in low quantity, if at all generally. Driver PCB would have to be
replaced, not worth it at the moment, so it will be kept for parts or other usage.

If you refer to the driver IC, GW05 is only a marking code which usually does not resemble the orderable part number. These packages are too small to mark the full part number. There are directories of cross-reference of these codes somewhere online. Otherwise it is yet to be identified.Dave,
Thank You for your follow up reply .
I'd give Digikey a look. They might sell the single piece, and not bulk, or replacement if they are still made???
