Anyway, can't wait to try it tonight.
And the quick review of the XM-L drop-in is that it's great. Definitely a noticeable step up from the XP-G.
Rated at 700 lumens, spot on. Only had the 630 TK40 to compare it with and it looks just as bright. At these levels even the ceiling bounce was hard to gauge with just my eyes as to the difference. What was really good was the throw. It lights things up better than the TK40 at a distance. I don't really have any other throwers but this is great. 100 metres, not a problem, the tree on other side of the football field was lit in all it's glory.
Tint on my XM-L was a bit green around the edges when compared to the TK40, which now seems a bit blue. Initially I didn't notice the green and though that the overall tint was a little bit warm. Very happy with the unit. Have to keep the head out of focus as the light is just searing when it is tightly focused and you turn it on near a wall.
Unit was easy to install as usual. I put it in my 4D and the head did get warm after 5 minutes. Not blistering hot let alone hot. On a side note, the Tenergy centura LSD D cells didn't have a problem with amperage being drawn from them.
