Planning notes

Best use

Comparing a narrow 300-watt full-spectrum fixture for a 2×4 tent or bench.

Before you buy

Confirm hanging clearance, controller compatibility and the current base package before adding accessories.

Strengths noted

  • The long fixture geometry is purpose-built for a 2×4 canopy.
  • IP65 protection and passive cooling suit humid indoor environments.

Considerations

  • The base listing does not include the optional smart controller.
  • Coverage and yield figures are manufacturer claims rather than independent test results.
