Buying Guide
- Coverage and layout: For large tents or multi-plant benches, consider fixtures that offer broad coverage or modular stacking. Daisy chaining and linkable designs simplify scaling without extra controllers.
- Spectrum balance: A mix of red (around 660-665nm), white (3000K-5000K), and optional IR (730nm) supports vegetative growth and flowering. More mature grows may benefit from adjustable spectrum options.
- Power efficiency: Compare wattage to PPFD and coverage area. Higher efficiency reduces operating costs, especially in longer grow cycles.
- Heat management: Look for fixtures with passive cooling or efficient heat sinks to minimize ambient temperature rise in enclosed spaces.
- Installation flexibility: Clip, hanging, or surface-mount options help tailor layouts to tent dimensions or shelf configurations.
- Durability and warranty: A longer warranty reflects build quality and support, particularly important in energy-intensive setups.
- Maintenance and replacements: Consider availability of spare parts, common replacements, and ease of cleaning the lenses and heat sinks.
