my observation (from local retail perspectives) is that mag ballasts still cheaper to purchase than that of electronic ones (averaged 10bux less per 2x 4ft T8 style), which to me is a farce.
Like you said: electronic ballasts cost less to manufacturer than iron lams and copper windings, so theoretically speaking: retail price should be more appealing than mag ones...but alas, no, not the case here.
(been like that for 10yrs now, unlike Asian countries such as Japan, Korea, etc. where electronic ballasts are a norm for over 2 decades now).
