I took my Night Train to bed last night...had to see it the first night, right? Anyway, I turned out the light, keeping my glasses on, and checked out the tritium. It looked nicely bright, and the blue minute markers are very cool...but it didn't exactly knock my socks off. But I think part of that was due to the fact that I had just turned the light off, and my eyes' pupils had not fully dilated yet.
I can tell you this, because I woke up in the middle of the night(as I oftentimes do nowadays ), and my arms were underneath the covers. Not even thinking about the NT, I pulled my arms out from under the covers, and my eyes were suddenly shocked by the major brightness of the NT's tritium tubes! I got out of bed to use the bathroom, and was amazed at how bright the tritium now appeared to be(compared to how it seemed when I first went to bed). It was especially cool how I got a double hit of the tritium tubes' brightness, as the glow reflected off the master bathroom mirror right back at me!
Have you spent the night with your Night Train, yet?
