Required Field *
Please Note: Default specifications "DF_XXX" will not appear in the ordering code.
LIGHT SOURCE *
To ensure color consistency, SPI uses precise bin selection and strict quality processes to maintain a 3-step (MacAdam) SDCM on all white LED lampings. Published LED luminaire wattages are calculated using a typical power supply efficiency of 88%; exact wattages may vary based on application. Alternative wattages available upon request.

Lamp Options *
Apply multiplier from chart for delivered lumens at other CCT’s and CRI’s.
Extended lead times may apply for controls other than 0-10V. Contact factory for additional control options such as Current NX, Enlighted, Encelium, Wattstopper, WaveLinx, Casambi, or others.
2 Not recommended for natatorium environments without additional component protection. Contact factory for options.
Mounts over standard 4” octagonal junction box with auxiliary mounting holes. When STM2 is specified, power is on the left stem when facing the front of the fixture.
Optical Orientation *
Specify the direction of light.
When the NAT option is selected, you can feel confident that the luminaire specified is designed with high-quality materials that will withstand the corrosive environment of indoor pools. Electrical components are protected from moisture and the fixture has been tested to operate in warm ambient temperatures.
Other Than Standard Options
Specify overall height required from the ceiling to the bottom of the fixture. The OAH min/max range is determined only by the physical limitations of the luminaire. Appropriate mounting heights are separately calculated from photometric lighting layouts and recommended from the specifier. If the specified mounting height is outside of the OAH range, please contact the factory.
