Spider Farmer SF300 33W LED Grow Light – 2.3 µmol/J Full Spectrum for Seedlings & Indoor Growing

The Spider Farmer SF300 33W LED grow light is a compact and energy-efficient solution for seedlings, cuttings, and small indoor grow setups. Equipped with 192 high-brightness diodes, this light delivers a powerful light output of approximately 4800 lumens with an efficacy of 2.3 µmol/J , while maintaining a power consumption of just 32–33 watts.

Thanks to the integrated reflectors, the light is better focused and evenly distributed, resulting in a higher light concentration and more efficient photosynthesis in compact spaces such as grow tents, cabinets, shelves and countertops.

Sunny Full Spectrum

With a 120° beam angle, the SF300 provides a balanced full spectrum light suitable for every growth stage from germination to flowering.

The spectrum contains:

• 660–665 nm (Red)
  
• 730–740 nm (Infrared)
  
• 2800–3000K (Warm white)
  
• 4800–5000K (Blue)

This spectrum supports strong root development, compact vegetative growth, improved flowering, and efficient chlorophyll production. Ideal for vegetables, herbs, microgreens, and houseplants in small indoor spaces.

High Light Output with Low Energy Consumption

With an actual consumption of only approximately 32 watts, the SF300 offers an energy-efficient alternative to traditional T5 fluorescent lamps. Thanks to the improved light focus via reflectors, you achieve a higher output per watt consumed.
