I found a YouTube video of the Station Nightclub fire and took a screenshot of what looks like a Wheelock MT.
As you can see, there is a crap quality picture of the white strobe housing as the MT or LSM strobe would have.
Here is a picture from the video not zoomed in.
This is a link to the original video. As you can see when the wall in the second picture is in view, a strobe flash can be seen.
Feel free to post your own opinions concerning this matter.
