What the Q400 Quantum Board is for
The largest fixture in the board range: four Samsung LM301B panels on a two-rail hanger, knob-dimmed, passively cooled. Where the Q100 and Q200 light a tray or a bench, the Q400 is sized to cover a small grow area from a single hang. Board dimensions and photometric data are supplied per order — ask us for the measured numbers before you plan a layout around it.
What you get
- Four-panel board array on a two-rail hanging frame.
- Samsung LM301B diodes, the same type used across the Q100 and Q200.
- Single dimmer knob, 0-100%.
- Passive cooling — no fans, no filters, no service in the canopy.
- One hang, one power drop for the area a multi-board layout would otherwise need.

Before you spec it
How does the Q400 compare to the smaller boards?
Should I use the Q400 or a top-light panel for a 4ft × 4ft bench?
For a documented 4ft × 4ft flowering bench, take the SF 880D ECO — 2,464 µmol/s with a published PPFD map, coverage figure and five-year term. The Q400 is a board-format alternative for buyers who specifically want that form factor; we are not going to claim it matches a fixture whose numbers we can show you.
Why is there so little data on this page?
Because we would rather have a short honest page than a long one with invented numbers. The board range is being re-specified with the factory; measured photometrics will be published here when we have them.
Can I get the data now?
Yes — send us your application and we will request the measured file from the factory.
