The compatibility between UV germicidal lamps and ballasts is very important, but which is often ignored unfortunately during practical application.
There are magnetic ballasts and electronic ballasts in the market, but the latter is more environmental than the former, saving energy. Lightbest can provide multiform electronic ballasts and inverters compatible with lamps.
