Up here in Northwestern-Central East California, all the new development is pure LED, but the “blast-on” feature—that would surely decimate incandescents—seems to have gone out of style.
I understand that Hewlett-Packard {LEDs and everything else} and CalTrans {state road dept.} did a lot of development work up to several years ago. A ~100K town in the region carried an evening news report of getting a $150K rebate for signal retrofits from PG&E [“inspired”/ramrodded by the state energy commission, no doubt.]
For retrofits around here, changeouts are not wholesale in the heads—some green, some red, some both, fewer amber—but way too many obnoxious ADA “chirpers.”
