This HPS Lamp 400W 240V, pulse-start lamp, has been engineered for use with Lumatek 400W 240V electronic ballast and is produced using high-grade ceramic arc tube technology and specific horticultural gas blend that creates optimal spectral output for healthy plant growth.
The PCA ceramic arc tube permits the lamp to operate at higher internal temperatures increasing colour rendering, output and efficiency. PCA resists interaction with the chemicals inside the tube which stabilizes the chemical mix over the life of the lamp, thereby improving colour consistency and PAR/PPF level maintenance. Pulse-start technology enables faster start up & restrike time, longer lamp life and increased lumen maintenance.
