Published footprint
Separate vegetative and flowering coverage claims, then match the intended footprint to the room.
What to compare
Actual input power
Use rated input watts for electrical planning. Do not treat model names or equivalent-watt marketing as measured load.
Fixture geometry
Check length, width, bar spacing, driver location and the clearance required above and around the fixture.
Controls
Record whether dimming is onboard, app-based or dependent on a separately sold controller.
Evidence date
Treat every price and specification as a dated snapshot and confirm the current model before ordering.
Before buying: confirm the exact model, package contents, current price, availability and compatibility at the manufacturer or retailer.
