UV lamp (Grainger# 2EWY8) used in 2EWX9 12V car unit ($140+). I just want the ?exciter? & power for the lamp for a small water UV device in the solar boat's water circulation line. Lamp is 85mm X13mm X4mm & will slip into sealed Pyrex test tube for its use. Lamp has a micro drop of mercury inside. I can cannibalize 2EWX9 but rather build off a less costly/destructive 12/24V compact solution. Is there a somewhat common starter for these lamps?
