Ultra Dense Bridgelux Array for Superior Growth
The G4500’s secret sauce? A high-density array of American-made Bridgelux diodes. These diodes are known for their reliability and output quality, providing an exceptionally balanced full-spectrum light that plants love. The spectrum includes a rich red peak in the 660-665nm range, perfect for promoting flowering, fruiting and overall potency. This red spike enhances flavours, boosts aromas, and encourages heavier yields - ideal for growers looking to take their plants to the next level.
Plus, the G4500's dense diode layout ensures deep light penetration and minimizes hotspots, offering uniform light across the canopy. So, whether you’re cultivating in a 2’ x 4’ core area or stretching out to the max 3’ x 5’ coverage, every inch of your grow space will benefit from consistent, high-quality lighting.
Cool. Quiet. Efficient.
Spider Farmer has crafted the SF G4500 with a bar-style design, and it’s more than just good looks. This setup enhances airflow through your grow tent, helping keep temperatures in check and promoting healthy growth across the entire canopy. The bar structure allows light to penetrate deeper into the plant, ensuring lower branches and buds receive ample light for even, full growth.
And here’s a big bonus for those who value quiet operation: the G4500 runs completely silently too. No fans are needed thanks to its passive cooling system, which uses heat-dissipating materials to maintain low temperatures naturally. With 0 dB noise, this light is perfect for stealth setups or shared spaces where peace and quiet matter.
Built To Last. Durability You Can Count On.
Spider Farmer understands that growers need equipment that can keep up with demanding schedules. Built for durability and longevity, the SF G4500 boasts an impressive 50,000-hour lifespan meaning it’ll keep delivering peak performance season after season. This light is crafted with high-quality materials that stand up to the rigours of daily use, so you won’t need to worry about replacements anytime soon. And to back it up, Spider Farmer includes a solid warranty - a testament to the confidence they have in this grow light’s reliability.
Digital Dimming for Precise Control
Whether you’re fine-tuning for seedlings or ramping up light for flowering, the digital dimming feature on the G4500 gives you pinpoint control over your light intensity that simply isn't available with other LED Grow Light brands. Compatible with 0-10V universal controllers, this dimming system is designed for advanced growers who want precise management of their environment.
