The 400W 240V HPS Dual Spectrum E40 Grow Light Bulb is a pulse-start lamp designed for use with the Ref#613052. The bulb is manufactured using high-quality ceramic arc tube technology and a horticultural gas blend that generates an optimal spectrum for plant growth.

The bulb can operate at high internal temperatures by taking advantage of the PCA ceramic arc tube technology, thereby improving color rendering, output, and efficiency. This system stabilizes the chemical mix throughout the life of the lamp, achieving consistency in color and PAR/PPF level. When starting by pulses, it starts up faster, has a longer lifespan and maintains better light.
