Guarantees accurate and repeatable print exposures without the use of expensive voltage regulators by turning any printing system (contact or enlarging) into a closed-loop, feedback system. With a strategically mounted MetroLux II® photo sensor monitoring light output during exposure, the MetroLux II® Darkroom Lamp Controller compensates for intensity fluctuations by extending or shortening exposure lengths.
Since 1986, Redlight Enterprises has provided a cost-effective tool to eliminate the problems that photographers faced with voltage fluctuation, coldlight drift, and lamp aging. MetroLux II® is so versatile, it is used by photographers exposing platinum prints outdoors, compensating for cloud cover during exposure.
In 1993, the MetroLux II® Darkroom Lamp Controller introduced many new features:
Expanded time base: 0.1 to 9990 lux or seconds
Dual Calibration Channels w/ Three Memory Locations
Hold/Reset Option during exposures
Built-in Shutter Tester
Remote Sensor/Projection Densitometer Accessory
Compatible with Variable Contrast Heads
Lamp Decay Factoring
Dual Calibration Channels are ideal for use with twin-grid Variable Contrast coldlights. Due to rugged circuitry, no contactors are necessary for use with grid lamps up to and including 12" x 12". Battery-free, Nonvolatile Memories never forget calibration and exposure values.
Built-in camera Shutter Tester times exposures of 1/2000 to 6 seconds on focal plane and leaf shutters.
Lamp Decay Factoring computes light fall-off at the end of each exposure. Now, a "burst" printing of 5 two-second exposures equals a single ten-second exposure.
With the Remote Sensor accessory, projected light intensities can be measured at the easel to help determine contrasts, match grey-values, or automatically recalculate exposures during print-resizing.
