Typical Lighting Retrofit Practices

·  Non hi-bay fluorescent lamps will be 4100K in color with a Color Rendering Index (CRI) >80.

·  F54T5 49 watt hi-bay lamps will be 5000K in color with a CRI >80.

·  Most fluorescent retrofits will use 25 watt F32T8 40K+ hour lamps with a CRI >80 and 95% efficient ballasts with a “normal” ballast factor.

·  Most fluorescent retrofits will use 2 lamps. Use “high output” ballasts rather than more than 2 lamps if needed.

·  Clear prismatic lensed 4’ long fixtures will have lamp and ballast retrofits and may be delamped to 2 lamps.

·  Clear prismatic lensed 2’ long fixtures will be retrofitted with F17T8 lamps and ballasts.

·  Abandoned sockets will be filled with silicone.

·  Sagging, broken and discolored lenses with be replaced with 0.125” thick clear lenses of equal pattern.

·  Louvered fixtures will be gutted and 2 lamp “volumetric” retrofit kits will be installed.

·  Bi-Level switched fixtures are not always justified and can often be retrofitted with one ballast and 2 lamps on one switch. Make a recommendation and have the Owner make the decision. Leave second switch leg abandoned in place if only one light level is used.

·  Bi-Level switching can be maintained by gutting the fixture and retrofitting with a Lithonia RT5R bi-level with F28T5 lamps.

·  If linear fluorescent dimming is needed, retrofit with Lithonia RT5R and Advanced MK VII or Mk X dimming ballast. Line voltage dimming is preferred.

·  All dimming must be reviewed by Owner prior to installation.

·  200 watt and higher HID fixtures will be replaced with 49 watt F54T5 fixtures and >93% efficient ballasts.

·  Smaller HID will be replaced with compact fluorescent or LED.

·  Most spaces with 8 or more lamps will have vacancy sensors installed.

·  Lighting attached to building exteriors will be photocell controlled if appropriate.

Miscellaneous Requirements:

·  All EXIT signs will be replaced with LED.

·  Incandescent medium base lamp fixtures < 100 watts will be replaced with screw-in CF or LED.

·  Incandescent lamp fixtures >100 watts and small HID retrofitted or replaced with separately ballasted CF using triple tube (TRT) amalgam lamps.

·  32 watt and 42 watt TRT CF may be replaced with lower wattage lamps if enclosures do not dissipate heat well. For instance a 32 watt lamp in a 6” can” will be replaced with a 26 watt lamp.

·  Other CF fixtures will not be retrofitted.

·  MR-16 HIR will still be allowed for many applications.
