Notes:
1) Lamp voltage in the luminaire should not increase by more than 5V when compared to lamp voltage in free air.
2) Ballast protection required, according to IEC61167.
3) 35W & 70W data is based on operation from a conventional magnetic ballast. Improved performance can be achieved using an electronic ballast.
4) 35W 4200K CMH lamp is based on operation from an electronic ballast. Lamps can run on conventional ballast with a small reduction in performance.
5) 20W designed for operation only from an electronic ballast.
