Here are two USA manufacturers of UL listed/recognized Constant Current LED drivers. I have used both of their products and they are both excellent, (and of course not at all cheap).
Magtech Industries (Las Vegas), possibly the LF1048-48 would work for you, you can take a look at them here;http://www.magtechind.com/engine/fil...4Os2yuTCKz.pdf
They tend to have some units on hand and they also have stocking distributors listed on their website.
Thomas Research, possibly the LED50W-48-C1050 will be right for you, you can take a look at them here;
You pretty much go direct to the manufacturer for these, they are in IL.
The voltage and current specs you mentioned seem a bit odd to me, and I took a look and couldnt find any bridgelux products that use those, if you tell me which model number you are using I could possibly be more specific about what specific driver might work for you.
The bottom line with local inspectors is that they are GOD and they can approve or reject anything they actually want to in my experience.
We use 3 of the the bridgelux
in one of our overhead fixtures and it is one 'butt-kickin' LED as far as I am concerned.
