Source: wholesale.mars-hydro.com (verified 2026-07-11) · corroborated by hydrobuilder.com. The official Mars Hydro wholesale page (wholesale.mars-hydro.com) titles the exact model "FC-E6500 730w USA MSRP 489.99 USD" and carries a full SPECIFICATION table (730W±5%, PPE 2.8 μmol/j, PPF 2026 umol/S, BridgeLux, 3546 chips, IP65, 5-year warranty, WEIGHT(KG) 10.72), confirming both the US MSRP and the model identity. Hydrobuilder (retailer) independently lists the same "Mars Hydro FC-E6500 730 Watt LED Grow Light" with matching specs (730W, 2.8 μmol/J, 2026 μmol/s, AC120-277V, IP65, 5-year, 4x4 flower / 5x5 veg coverage, 3546 BridgeLux chips) and a Sale Price of $489.99, corroborating the price and the numbers. Both pages identify this as the 730W USA Bridgelux version — distinct from the EU 680W unit and the Samsung EVO siblings — so identity is verified; the noisier Amazon listing (conflicting 2044/2140 PPF and 3-year warranty from cross-contaminated fields) was deliberately excluded as a source.
