The 69th Annual Tony Awards are on CBS tonight at 8 pm. I was at the rehearsal this morning (see below) and I can tell you that it’s going to be a good show. Kristin Chenoweth and Alan Cumming are great fun. Check out this year’s nominees for best play and best musical (you can even stream it!), then get yourself some theatre tickets.
The spring semester starts this week for my Pratt students and next week for my Parsons students. The beginning of the semester is always a little hectic and stressful. Here’s a bit of fun to take the edge off. Not many forms of energy have their own song. Here’s “Electricity” by Orchestral Manoeuvres In The Dark (aka OMD). It’s so painfully dated that it’s funny.
No family get together or holiday party is complete without a yule log. Here’s one…
On Tuesday, April 15, the U.S. Department of Energy’s (DOE) Solid-State Lighting Program will host a 60-minute live webinar entitled LED Color Stability: 10 Important Questions. The webinar will begin at 1:00 p.m. ET (10:00 a.m. PT) and will include a 45-minute presentation followed by a 15-minute question-and-answer session with attendees. IES continuing education credits will be offered.
The lumen maintenance lifetime of many LED products is 25,000 hours or more, but that doesn’t mean products are guaranteed to perform the same over that time. One thing that could change is the color of the light, or chromaticity. This webinar will examine the causes of color shift, and look at existing metrics used to describe color shift/color stability in LED lighting. Are there established tolerances for color shift? What current standards apply to the measurement of color shift, and are there plans for new methods and/or standards for projecting color shift in the future? Presenters Michael Royer of Pacific Northwest National Laboratory, Ralph Tuttle of Cree, and Chad Stalker of Philips Lighting will answer these questions and many others.
Next Friday, the 21st, I’ll be speaking at the 24th Annual Symposium on Public Monuments in New York City. The symposium is on the legacy of the 19th century architect Patrick Charles Keely. I’ll be speaking on my relighting of his Church of the Holy Innocents on 37th Street in Manhattan. For more information, go to www.monumentsconservancy.org.
Here’s what the church looks like today.
