Solux 350

The Solux 350 is HortiBloom's straight swap for a 600W HID. They built it to the physical size of a 600w HID fixture deliberately, so it drops into an existing layout without moving hangers or rethinking spacing.

Efficacy is 2.9 μmol/J and the PPFD is spread over 4'x4'. HortiBloom's own comparison testing in a 4'x4' tent claims it beat a 1000W HID at both centre and edge readings while saving 40% of the energy — their figures, not independent ones, but the edge reading is the right thing to be measuring.

It carries a 5 Years Warranty and HortiBloom offer a full refund if testing fails. For a retrofit, matching the fixture's footprint to the old one is worth more than a slightly better spec sheet.
