Instrument Lighting

UMA Instruments, Inc.

UMA’s technologically advanced lighting system is the ideal replacement for your existing post lights or indirect lighting system.

The EL (electro-luminescent) light does not use bulbs, but an electro-luminescent light strip housed in a black injection molded enclosure

ready to install. The light strip draws very low current and produces virtually no heat. Inside the strip, semiconductor crystals convert electrical energy directly into light energy. EL Bezels require AC voltage for illumination. A small inverter (see next page) converts battery DC to AC required by the EL. Light colors available are Aviation Green, Blue/White (FAA/PMA’d) and Red.

EL Lights are easy to install onto your existing instruments in just minutes. Simply place the light bezel between the instrument and the panel or between the instrument panel and the panel overlay. The EL Light, unlike conventional lighting systems, will not burn out and is guaranteed for the life of your panel. Bezels are available to fit MS standard 2 1/4” and 3 1/8" instrument cases. We have bezels with left or right cutouts, center cutouts, or dual cutouts to fit all your instrument needs.

Bezels require an AC voltage to power the lights. Each Inverter will handle up to 12 bezels at one time. Three models are offered for different DC input voltage ranges of 5, 14, or 28.
