I finally got my bulbs today, in fact I found a local source for them and picked them up today. They're surprisingly affordable.
Then I got home and loaded them up. I'd been putting up with the 90W Osram bulb that I'd gotten for testing, and when driven at 13V it is really yellow. It needs far more juice than that. And it started out badly - I put in the new bulb and it didn't light due to a bad ground contact that I spent some time troubleshooting. I probably need to wirebrush away some ano.
The 64625HLX on 4xA123 is absolutely AWESOME. You know, I'm kinda used to the white of LEDs, but when I fired up the 625, I was blown away by the nicest tint I've ever seen on an incan. It looks positively WHITE. Negligible voltage sag on A123s since they're designed for 120A (10 sec pulse) and 70A constant current discharge.
The ROP is supposed to be one of those that burns hotter and whiter and the ROP was totally drowned out by the 625. I flipped the ROP on and a fraction of a second later I thought the bulb blew because I couldn't see the hotspot. I pointed the ROP up and the bulb was still on - turned out that the 625 utterly blew it away.
Really one of those I cant keep the smile off my face moments - which are rare enough as it is these days!

The last time I worked with the 625 five years ago I recall I was very underwhelmed by the yellowish looking bulb. I am not really sure why, but on the USL platform I greatly preferred the 62138's characteristics. The problem was that I flashed half a dozen of them, which also greatly pissed me off. The 625 didn't flash but was not impressive looking at all.
I'm glad that's changed - the 625 is a new favorite on the A123 powertrain and AW's 3-stage incan D regulator. And it is GOOD to be back in incan land again!!
Thanks to mrQQ for the regulator - I have no regrets about buying this one
