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.
