Solarmax HPS bulbs are a high output, German‑manufactured lamp designed specifically for horticultural use. It delivers a balanced blue and red spectrum suitable for every stage of plant development, from early vegetative growth through to flowering. With a strong reputation for reliability and consistent lumen performance, it provides growers with a dependable lighting option for indoor gardens.
Engineered in an ISO‑certified facility with over 40 years of HPS and MH lamp expertise, the bulb offers targeted red light to support flowering while maintaining overall spectral balance. Its improved wire frame enhances compatibility with digital ballasts, and the single‑ended design suits most standard fixtures. This combination of spectral output, build quality, and longevity makes it a trusted choice for growers seeking stable, predictable results.

Care and Maintenance:
-
Allow full warm‑up and cool‑down cycles
HPS lamps are sensitive to thermal shock. Always let the bulb reach full operating temperature before switching off, and allow it to cool completely before turning it back on. This protects the arc tube and extends service life.
-
Handle only when cool
Never touch the bulb when hot. Allow at least 10 to 15 minutes for cooling before removal or adjustment.
-
Avoid touching the glass with bare hands
Oils from skin can create hot spots on the glass envelope. If contact occurs, clean the bulb gently with isopropyl alcohol and a lint‑free cloth.
-
Keep fixtures and reflectors clean
Dust and residue reduce light output. Wipe reflectors and glass covers regularly to maintain maximum lumen delivery.
-
Replace on a schedule
Although the rated lifespan is 24,000 hours, horticultural performance typically declines after 12 months of daily use. Most growers replace their HPS lamps annually to maintain consistent results.
