We built the factories to make professional LED grow lighting accessible to every grower.
Automated SMT diode placement, gluing lines and fixture assembly controlled in-house in Dongguan: full traceability per batch. 130+ patents & certificates, 32 invention patents.
Every fixture runs a burn-in cycle on our aging racks before packing; per-batch test reports ship with orders so your receiving QC can verify, not just trust.
In-house integrated sphere lab verifies PPF and PPE per model; PPFD maps issued with test conditions stated: the numbers we quote are the numbers we measure.
LEDs from Samsung / OSRAM / Epistar / Ledestar / CREE and drivers from UL-listed Sosen or MEAN WELL: named suppliers, BOM disclosed to OEM partners.
Operational warehouses in the USA and Canada with ready-to-ship models dispatched within 48 hours; experienced engineers can fly on-site for after-sales support.
