Osram Vialox- 400 Watt S-T-P (Red Spectrum Lamp)

SHP-TS Super flower bulb Affordable, reliable, and powerful. Like all of the lamps in this series, what stands out is the price, but also excellent performance values. Sylvania is a subsidiary of Osram and has certainly made a name for itself in the world of grow lights. The lamps in the Sylvania SHP-TS series emit a large proportion of their light in the red spectrum (approx. 2050°k) and are therefore best suited for the flowering phase of most harvest crops and ornamental plants. The manufacturer states that the lamps have an average lifetime of 30,000 hours in operation, which makes the Sylvania SHP-TS lamps not just good value, but also relatively long-lasting.
