Ditch inefficient, power-hungry T5 fluorescent tubes and transition to sleek, high-output LED technology. The Spider Farmer SF300 (33W) and SF600 (74W) are ultra-slim, lightweight light bars engineered specifically for propagation shelves, cloning racks, kitchen countertops, cupboard grows, and micro-vegetative setups.
Operating in complete, fanless 0dB silence and generating minimal heat, these plug-and-play panels are coated in a moisture-resistant protective layer—making them ideal for high-humidity propagation domes and indoor seed-raising kits.

Core Performance Features
-
High-Density Light Emission: Utilizing up to 384 premium diodes per bar, these panels achieve an impressive light output (74.92 µmol/s for the SF300 and 166.81 µmol/s for the SF600) with a wide 120° beam angle. This guarantees dense, concentrated light coverage right across your plant trays.
-
Targeted Veg & Propagation Spectrum: Fine-tuned to facilitate rapid germination, robust rooting, and intense chlorophyll synthesis. The spectrum combines 4800-5000K (cool blue white) for tight node stacking, 2800-3000K (warm white) for structural growth, alongside 660-665nm (deep red) and 730-740nm (infrared) wavelengths.
-
Streamlined Plug-and-Play Design: No bulky, complicated drivers or wiring configurations to worry about. Simply hang the light using the included hardware, plug it straight into standard UK mains, and begin growing. Its slim, low-profile form factor saves valuable headroom in tight spaces.
-
5-Year Local Support: Built for a lifespan of up to 50,000 hours. Authentic Spider Farmer fixtures include a dedicated 5-year after-sales warranty service operated directly from our specialised UK repair centre.
