JRL's patented technology is an automatic adjusting (dimming) electronic ballast with fiber optic sensors, sold under the trademarked name Just Right Light®.

Until now, dimming of fluorescent lighting could only be accomplished through a separately wired, manually operated and expensive control system.

Technology Description:

• Just Right Light® units work using variable control of the frequency at which the electric arc flowing through the gas column of a fluorescent lamp tube is reversed.
  
• Just Right Light® uses light feedback through fiber optics to generate a control signal. That signal is used to continually adjust the light output of the lamps if there is any deviation from the preset ambient light level.
  
• When daylight is present, the light output proportionately adjusts down; the converse takes place when daylight decreases or when depreciation or other diminishing factors occur.

Best Applications

• Lighting upgrades of buildings with magnetic ballasts and T-12 lamps
• Lighting upgrades of buildings using electronic ballasts and T-8 lamps that are over-lit
• Construction (new buildings) and renovations (existing buildings)
• Large areas of fluorescent-lit space, such as
  • Schools, colleges and universities
  • Institutional, government and military buildings
  • Hospitals and health care facilities
  • Office buildings
  • Manufacturing facilities
• Buildings with specific controlled lighting needs

How It Works

1.	Just Right Light® ballasts are the same size as standard electronic ballasts, and are installed as easily and economically, (with minimal work required to install fiber optic cables and sensors). JRL's Just Right Light® ballasts are installed into existing fixtures at the site or Pre-installed into new fixtures which are then shipped and installed.
2.	JRL's technology provides a Just Right Light® environment that is personalized to the task(s) being performed and people performing the tasks. Each luminaire (fixture) is adjusted and preset (using the internal fiber optic sensor) to provide the amount of light recommended by IESNA standards (or other standard as requested by the user) to the area being illuminated.
3.	Just Right Light® ballasts automatically and continuously adjust the light output of the luminaire to compensate for changes in ambient light (daylight harvesting) or reductions in lamp output (lamp depreciation) Once the lighting level is preset, the Just Right Light® ballasts act as "thermostats" for each luminaire, maintaining the set level regardless of ambient light or lamp depreciation.
4.	JRL's technology provides the ultimate flexibility. Changes in layout, space usage, etc., requirements are easily accommodated because the lighting environment can be quickly modified (higher or lower) with a simple adjustment.
