It took a while for batteryspace to ship all the parts, but I finally got them today. The lamps they sent were just a tad taller than the originals. One of the lamps just barely fit inside the housing. The fit is acceptable, but another source for the lamps might not be a bad idea if you didn't want to take the chance of them not fitting.
I put a fast charge on the battery and gave the lights a test. The lights ran for 72 minutes before the light started to fade. I was hoping for 82 minutes, but my commute is less than 1 hour, so I'm still in good shape. I really like the charger. It has two different charge rate settings which are .9A and 1.8A. This is pretty handy because it takes about 2 hours on the 1.8A setting. If you're leaving it overnight, you can put it on the .9A setting. Slower charging is easier on the battery. The charger shuts down to a trickle charge once the battery is full, so you can leave it on overnight using either setting. The battery has a charging port which provides thermal shutdown for added protection. With both lamps running, I read 3.3A on my meter, which is exactly what I anticipated. I'm going to charge the batteries overnight and try another test.
I've only looked at the light indoors, but it seems to be exactly what I wanted. You can really tell the difference between the spot and the flood and both complement each other well. I'm very interested in finding out how they perform on the bike.
