  2. The professional shall submit PDF computer generated point-by-point calculations of most interior spaces to Engineering Services for review.  The use of certain “typical” rooms shall be acceptable except when the amount of fenestration or the room orientation changes.  Show calculations for each space without daylight contribution as well as with daylight contribution and lighting controls.  Point levels shall be legible, shown on a scaled drawing.  All pertinent calculation parameters shall be indicated, highlight where the design is non-IES compliant.  Engineering Services will provide direction and variance where deemed adequate.  Utilize AGI-32 full calculation mode or similar program, as approved by Engineering Services.

Systems shall offer a range of temperature control from 2700K through 6000K, dimming control from 100% to 1%, and shall offer compatibility with any LED dimming driver/controller including 0-10V, DALI, DMX, etc. Controller types and deployments shall be reviewed with Engineering Services.
  4. Linear LED lamps (T-8/T-5 types) intended to replace equivalent fluorescent lamps shall be deployed using a connection to a ballast for operation. Line-voltage or hybrid linear LED lamps bypassing a ballast shall not be utilized. Dedicated LED/driver linear lamp deployments are acceptable with drivers meeting the minimum standards specified elsewhere. LED lamps connecting to a ballast with end-of-life circuit protection shall not be used for normal/emergency or emergency illumination requirements.
  5. All LED deployed luminaires shall include field replaceable LED drivers capable of access without removal of ceiling systems or other building components to replace or service the driver.

  8. The use of other fluorescent lamps is discouraged.  Linear T5HO (high-output ) fluorescent lamps are allowed where design applications exist, but only as approved by Engineering Services.
  9. Compact fluorescent lamps shall not be specified.  LED luminaires or lamps shall be specified instead.
  10. Coordinate other lamp wattages and styles with Engineering Services prior to specification.

  16. LED screw-in lamps using medium base, GU24, GU10, bi-pin etc.  shall be approved by Engineering Services prior to specification.  PSU prefers purpose-built LED luminaires over socket based solutions. Lamps shall provide flicker-free dimming to 10% where permitted or required.

.03 Ballasts & Drivers
  1. Fluorescent ballasts shall be NEMA “premium” efficiency, electronic, CBM and ETL approved with a sound rating of A.  Ballast shall also be Class P, thermal cut-out switch, rated where required by U.L.  Investigate use of high or low ballast factor as part of the illumination calculations.  Linear ballasts shall be as follows:
