Diamond Vision flood beam CRT's. Predecessors to today's bright RGB LED's in large display signs. They differ from the CRT tubes used in old monitors by being small, and having a nonfocused electron beam “flood” spraying onto single color phosphor. Diamond Vision once had a rooftop sign near Times Sq. at 47th@7th, but large LED signs have now taken completely over.

Choosing an LED bulb is like finding a romantic partner: You gotta know what you’re looking for, so you know when you’ve found it.

Prototype LED light on Murray St. where the entire mast holds the lights on the bottom. Thought it was ugly, and happy that with new even brighter LED's, they finally went with new cobrahead models that can fit onto existing poles.

Color scale a fellow railfan produced showing possible color ranges for subway line map colors.  Hues 170 and/or 200 are allotted for the future 2nd Ave. subway (later phases, when it goes below 63rd. Segment being constructed now will be an extension of the existing [yellow] Broadway line).  Hues 152 (sea green), 272 (an even purple), 320 (an even pink) and 244 (like a cerise red) are unused. I've suggested using the deeper version of yellow (hue 56) for Bway.

My own BetaBrite Prism (from Amazon, for an amazing $69; when it's worth about $300 new!) showing off the colors (which are distorted by the photography), and how it can be used for transit. I have been putting it in the window with holiday messages for the past few years.

The block I grew up on looks cool with the new LED street lighting (which is all over that side of Bklyn, but nowhere to be seen over where I am yet). Reminds me of before '74-5, when they began replacing the old white mercuries with the orange sodiums. The one in the foreground (top) held out until '82 for some reason. Never thought 40 years later, they would be white again!
