I read an interesting article on another hydroponics message board claiming that electonic ballasts are not suited for use with the vast majority of HPS and metal halide bulbs on the market. This is contrary to what I have read and heard in magazines , hydro stores, eballast manufacturer's info,etc. The writer asserts that although the e-ballast may light the bulb, that bulb will fail prematurely and cause the release of hazardous gases or subtstances. The article states that most HID lamps are made to operate at 50 - 60 hz, whereas e- ballasts operate at 22,000 hz and higher.

Can someone confirm or refute this for me? I recently purchased an e-ballast with the understanding that it can effectively operate both HPS and metal halide lamps and am now concerned.

Thanks
