The Jerguson LumaStar EPL-316 Illuminator (photo) provides high-contrast, white LED light for any transparent glass level gage, delivering superior gage visibility in either day or night. With its 316 stainless-steel construction, the LumaStar Illuminator is suitable for severe service environments. It is approved for use in Class I, Div. 1, Group B, C & D and Zone 1 & 2 environments. A single explosion-proof power supply with intrinsically safe lighting circuit can service illuminators up to 58 in. long. The illuminators are field-upgradeable to fit any glass gage, says the manufacturer. — Clark-Reliance Corp., Strongsville, Ohio
