Sunmaster

Sunmaster is a long-standing name in indoor horticultural lighting, trusted by growers for decades who want reliable lamps that deliver strong plant development through every stage of the cycle. Built around stable output, consistent spectrum control, and dependable long-term performance, Sunmaster lamps help maintain balanced lighting conditions for healthier structure in veg and improved density in bloom. Their straightforward, grower-focused approach has made them a popular choice for both hobbyists and experienced cultivators looking for predictable, results-driven lighting.

Key examples include the Sunmaster 600W Super HPS Lamp, designed to deliver intense bloom-focused output for stronger flowering, improved canopy penetration, and reliable density, and the Sunmaster 10K Finishing Lamp, a specialised late-stage bulb that enhances ripening performance and supports improved final quality during the last one to two weeks of the cycle. Together, these lamps highlight Sunmaster’s commitment to providing clear spectral advantages at each phase, offering growers practical tools to fine-tune development from early veg through to harvest.
