I remember that they swapped the converter board and removed the "strong light" stamp. Did runtimes/output/reliability change as well?

Huh, didn't know they swapped the converter. What did they change in it?
I have one of the first NDIs, those that were sold at a discount in the first sales thread, so I must have the first-generation board.

I know the one I got from Edgetac out of the second run gave me nothing but trouble for months. The replacement I received from 4sevens around a month ago has worked perfect. I think they worked some of the flaws out although I can't tell you for certain of any specific changes.

The new clicky switches are a lot more reliable and they come with a spare switch now too.

I actually liked the "strong light" markings and wish they didn't remove those.

Another significant change in the latest NDI's is the addition of a split ring floating contact ring, similar to the D10. This is supposed to improve the longevity of the contact surface on the head's circuit board. I noticed this change on the GD version of the NDI. I would assume newer Q5's probably have this also.

How durable are the contacts on the original head? Or, in other words, can I expect them to wear out in the lifetime of the light, considering it doesn't see really heavy use?

The contacts will not likely wear out on you if you have the older batch considering the light doesnt rely on a twist action to turn it on. On twisty lights that get used alot, im sure they would wear out eventually.

Heres a question, if the newer NDI's have the exact same light engine as the D10, then why wont the light turn on when you screw the head on like the D10 does?

I still twist it all the time to change mode...

It doesn't have the exact same light engine as the D10. It only looks the same now that it has the floating split ring. It has to be programmed differently since the D10 doesn't have strobe, whereas the NDI does.
