No. 01 — High-efficiency flowering in 2x2 tents
A standard 100-watt class board suitable for two-by-two foot vegetative or flowering areas. The full-spectrum white output allows comfortable daily canopy inspection and delivers an even PAR spread across small footprints. Always verify the PPFD map against your tent height to prevent light bleaching on upper foliage.
No. 02 — Budget-conscious 2x2 grow tent setups
An entry-level 100-watt fixture sized for a standard two-by-two foot footprint. Its full-spectrum white output provides practical viewing in domestic spaces, avoiding the visual fatigue of blurple LEDs. Review the manufacturer PPFD map at your intended canopy height rather than judging capability by nominal wattage alone.
No. 03 — Overwintering single houseplants in standard lamps
A screw-in A19 bulb intended to deliver supplementary light via standard domestic lamp fixtures. The full-spectrum white profile integrates cleanly into living spaces without turning the room purple. Because usable PPFD drops steeply with distance, foliage must sit close to the bulb to gain any real vegetative benefit.
No. 04 — Budget-conscious small tent or closet growers
Drawing 70 actual watts, this panel delivers substantially more usable PPFD across a small footprint than consumer clip lights. The integrated dimmer lets you dial down output for seedlings and ramp up as vegetative mass increases. Diode branding and exact efficiency metrics are unspecified, so rely on physical canopy height adjustments to balance heat and coverage.
No. 05 — Supplementary lighting for low-light desk plants
A multi-head desktop clip light designed to supplement low-light house plants on shelves or desks. While the goosenecks allow directional targeting, the red-blue color profile is distracting in rooms you occupy daily. The total PPFD is modest, making this suitable only for maintaining low-light foliage rather than driving dense vegetative growth.
