This is a state of the art test type designed for use at 6m. Illumination is achieved via numerous LEDs (Light Emitting Diodes) producing a bright, homogenous light. LEDs have an expected lifetime of between 30,000 and 50,000 hours eliminating the need to regularly change bulbs/tubes. The user can switch between illuminating the letter panel and illuminating the LED spot situated directly beneath the letter panel. Cabinet finished in a smart gloss white and supplied with a mains adaptor providing a 12V DC output. This unit is supplied with an adjustable wall mount (with screws) but is also available as a stand alone unit – please see SDT-903-L. Various letter panels available.
