The blue tint could have been because of DFN (day for night) photography. Night scenes are often shot in daylight, with the film under-exposed and using a blue filter to simulate night-time. At least, that used to be the case with celluloid - I don't if they still do the same nowadays with digital video.
There was a night guard with a (I presume) Streamlight Stinger, Incan, in the same scene. His light was normal white, not blue at all, while the smaller lights were definitely blue. I don't doubt for a second that they were, in fact, LED lights.
I know day-for-night; but usually, the day-for-night filters tint everything blue, not just the lights
.
That was not my question. My question was the brand -- and I thought they were G2Ls as well.
The scene in Bones was another good example of incan vs. LED -- Bones had the incan M6; Angel, I mean, Booth
, had an LED weapon light (X200?).
