Failing Alto Lamps at My Work There is a light fixture just front of my cubicle that I have snapped this picture. For the last 2 or 3 month, one light failed, but the other one was still shining normally. Until this shot, the normal light started to flash, then it came weird glowing discharge like this.

Such a cool effect! I have a few of the Motorola ballasts that do this when lamps fail at one end before the other! still need to get the 3 lamp version with that one one bad lamp causes all 3 to mercury migrate to the good end eventually

interesting! My school uses GE F32T8/CW EcoLuxes. Some of the older lamps are Sylvania T8s with green etches (either 25 or 28W ES lamps). My middle school used the Sylvanias and GEs like my high school but also last year they started using Service Long Life Garenteed (or some spin off that lol) which were i believe 25W ES lamps, also with green etches.

Phillips makes the service long life lamps usually
