How do you verify whether a fixture uses genuine Cree COB chips or standard diodes?

Check the product documentation for specific chip model designations such as Cree CXB3070 or Cree CXB3590 rather than generic LED marketing descriptions. Authentic Chip-on-Board fixtures house concentrated clusters of diodes under a single phosphor coating, whereas panels using standard surface mounts feature arrays of individual diodes like Samsung LM301B. If a listing mentions broad diode branding without a clear COB part number, inspect the technical diagram to confirm whether it features unified circular chips or spread-out surface diodes.

What is the difference between advertised wattage and actual wall draw?

Advertised wattage typically refers to theoretical diode capacity, whereas actual wall draw indicates the real electrical power pulled from your wall outlet. For instance, a 300W Cree CXB3590 light lists an actual wall draw power between 185W and 200W, and a 36W fixture can claim a 400 Watt equivalent rating while consuming only 36W. Always check the electrical specifications for measured power consumption to prevent overloaded breakers and manage your grow tent heat load accurately.

Do Cree COB LED grow lights use active fans or passive cooling?

Cooling methods depend on fixture wattage and heat sink design. Compact units like the waterproof 100W CFGROW 3500K feature natural heat dissipation without noise, relying entirely on metal heat sinks to shed warmth. In contrast, higher-output multi-chip units such as 200W four-COB systems or 580W arrays generally require internal cooling fans to move hot air away from concentrated diodes. If silent operation in a living area is essential, confirm on the product listing whether the fixture uses fanless heat sinks or motorized exhaust fans.

Which Kelvin rating should you choose for different growth stages?

Match the color temperature to your plant development phase, using higher Kelvin ratings for vegetative growth and lower ratings for flowering. A 6500K spectrum, such as a 65 Watts Viavolt unit producing 12,000 Lumens, provides cool light suited for compact vegetative structure, seedlings, and clones. For bloom cycles or entire seed-to-harvest runs, warm white options like 3000K or 3500K deliver red-weighted light suitable for plants across all growing stages indoors. For propagation racks or low-clearance seedling shelves where high-intensity COB heat would overwhelm tender starts, growers often use under-shelf lighting without exposed wiring as gentle secondary illumination.

How does light penetration compare between COB chips and SMD diode boards?

COB chips deliver significantly higher canopy penetration because they concentrate intense light from a single source, driving photons deeper into dense foliage before the beam scatters. Multi-chip configurations, such as a 200W fixture with 4 COB units, punch through upper leaf layers to illuminate lower branch sites that often starve under flatter arrays. Standard panels with spread-out surface diodes illuminate broad canopy tops evenly, but their dispersed light loses intensity faster in lower growth levels. For bushy crops with thick undergrowth, high-density COB focal points help prevent underdeveloped lower flowers.

What canopy footprint will a COB LED fixture cover?

Usable footprint depends on wattage, form factor, and whether the light uses concentrated lenses or wide reflectors. Mid-range units frequently cover 2x2 ft or 3x3 ft spaces, matching tent sizes supported by 1000W-rated panels, while commercial multi-bar 720W designs spread coverage across a 5x5 ft footprint. Because COB beams are concentrated, hanging height dictates whether your footprint provides concentrated center intensity or wider edge-to-edge coverage. Always confirm the manufacturer hanging height recommendations to ensure the light spread matches your tent dimensions.
