MASTER GreenPower 600w dual spectrum bulb The Philips Master Green Power 600W HPS lamp is a dual-spectrum lamp with a high 88,000 lumen’s output. The lamp produces light in the orange/red part of the spectrum for excellent flowering plus a generous amount of blue for healthy plants and vegetative growth. Lumen’s is a measurement of total light output, not the amount of light that plants can actually use. The Philips Master Green Power 600w HPS has lower lumen’s output than some other HPS lamps but it actually produces more usable light for your plants than any other making it the best lamp for growing plants that you can get. The Philips Master Green Power 600w lamp is built to professional standards and because of this it maintains it’s light output for much longer than other lamps, meaning it lasts longer between change-outs.

Philips GreenPower 1000W Sodium Bulbs are extremely high quality sodium bulbs that produce better growth rates and results from superior light output, spectrum and build quality.

Parlux - 600 Watt Bulb (Dual Spectrum)

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.

Plantastar-T dual spectrum bulb The Osram Plantastar HPS lamp is one of a handful of bulbs specifically designed for the horticulture market. The colour temperature rating of the Osram Plantastar is 2000k, which is firmly in the red spectrum. There is also a substantial amount of light in the blue spectrum to give a more rounded, balanced light for your plants. The Osram Plantastar uses the standard E40 lamp fitting, meaning it is compatible with all the standard reflectors and 240v ballasts. As such, you can simply replace your current 600w, 240v lamps with this plant specific lamp. It has been designed with focus on tall growing plants which may suffer from light drop-off to the lower leaves. The Osram Plantastar gives great penetration into the canopy. This delivers high PAR light to more photosynthesis sites that boost production of sugars, leading to better harvests.
