due to recent emails and information regarding the Energy Independence and Security Act of 2007 - there are certainly going to be a lot of questions and points of clarification that folks will be asking. Aside from the main lighting requirements, (CFL vs. Incandescent, etc), there is the requirement to increase efficiency in probe-start metal halide ballasts (to 94%) and pulse-start ballasts (to 88%), It might be worth asking/reviewing/discussing (in layman's terms) a few points;

a) what is the difference between Pulse start and Probe Start? (besides a pink socket?)

b) does this just apply to ED-17 lamps?

c) Most architectural lighting fixtures have begun to move away from ED-17 and towards T-6 lamps, what types applications and/or industries need to use probe start ballasts?
