For professional cultivators and OEM partners, we engineer high-efficiency LED systems for commercial greenhouse and indoor cultivation at scale. The range covers top lights 600W–1600W and under-canopy bars 120W–300W, stocked in China, the US and Canada. Every project is backed by free lighting plans and full OEM/ODM for brands and distributors.
Eliminate shade-stunted yields. Traditional top lighting often leaves lower bud sites in the dark, leading to 'popcorn' buds. By integrating SLTMAKS high-output Top Grow Lights with targeted Under-Canopy LED Grow Light Bars, you ensure every layer receives optimal PPFD. Our dual-layer strategy is engineered to maximize flower density, increase overall harvest weight, and deliver crop consistency. One Supplier. Total Coverage. Maximum ROI.
