The SHP-TS 600W SYLVANIA bulb is a tubular HPS lamp designed for flowering , offering reliable start-up and a warm spectrum. With 90,000 lumens , 2,050K color temperature, and an E40 base, it efficiently and consistently promotes flower density in indoor cannabis cultivation.

The SHP-TS 600W SYLVANIA bulb technology prioritizes red and far-red light to accelerate fattening, resin production, and uniform maturation in cannabis cultivation , while maintaining a slight blue boost that helps control internodes at the beginning of the generative phase.
The tubular design operates at 125V with 5.5A , integrates reinforced glass and delivers 90,000 lm at 2,050K , a warm “sunset” that the canopy takes advantage of very effectively.
In typical installations, this lamp performs at its best over areas of ~1.2–1.5 m² with an open reflector or cooltube type and a 600 W magnetic or electronic ballast . The useful life reaches 32,000 hours (preventive replacement is recommended after several intensive cycles to maintain flow and uniformity).
Reference dimensions: ø48 × 280 mm ; approximate weight: 178 g . To preserve performance, it is advisable to note the installation date, avoid touching the bulb with bare hands, and keep the reflector clean. The phase change is managed by photoperiod ( 18/6 in vegetative stage with a suitable light source and 12/12 with this HPS during flowering).
In hybrid systems, the SHP-TS is combined with perimeter LED grow lights , improving lateral coverage and homogeneity without excessively increasing the heat load.
The result is a uniform canopy, compact tails and consistent aromatic profiles, provided that ventilation, extraction and irrigation keep pace with the growth rate.
Designed for indoor growing in grow tents and medium-sized rooms, the warm spectral curve optimizes the filling of the middle and lower layers of the canopy. Ideal for Sea of Green (SOG) with compact plants or Screen of Green (SCROG) setups where a tightly stretched net receives even light. The 600W power output facilitates penetration into dense canopies, reducing shading and improving yields per square meter.
It promotes abundant flowering , bud fattening , and resin production in cannabis plants . The 2050K spectrum accelerates calyx formation and helps ensure uniform ripening at harvest. It is also useful during transitions from the vegetative stage when the goal is to accelerate the generative response by changing the photoperiod.
A solution with an excellent price-performance ratio for rooms seeking stable performance without complex investments. It allows for achieving ambitious goals at a lower cost compared to other technologies, especially when the installation is properly calibrated.
