EVERYGROW Outdoor Full-Spectrum LED Grow Lights 21.3ft String, IP65 Waterproof & Daisy-Chainable for Greenhouse Plants

EVERYGROW Outdoor Grow Lights are a 21.3-foot, UL-certified, IP65 waterproof full-spectrum LED string designed to deliver photosynthesis-supporting light for greenhouse and outdoor plants.

This weatherproof string light system combines broad-spectrum LEDs, daisy-chainable connectivity and durable construction so you can add consistent supplemental light to seedlings, potted plants and greenhouse benches. Built with aluminum housings and waterproof switches, the set balances luminous output and outdoor reliability while remaining simple to install and expand.

How does this grow light support different plant stages?

EVERYGROW’s bulbs blend cool, warm and targeted red diodes to cover wavelengths that contribute to both energy capture and structural development. The mix of 3000K, 5000K and 660nm red chips supplies light useful for sprouts, vegetative growth and flowering, making the same string suitable through a plant’s lifecycle.

• Full coverage from about 380–780 nm to stimulate photosynthesis and photomorphogenesis.
• Each bulb contains 48 LED chips for balanced spectrum distribution.
• 15000 lumens total output to brighten multi-plant setups.

Are these lights safe and reliable for outdoor use?

The system is UL certified and engineered with corrosion-resistant aluminum lamp bodies and effective heat dissipation to reduce light decay over time. Waterproofing features include sealed housings, a rubber-covered switch and vent holes to limit internal moisture buildup, making the string suitable for exposed greenhouse or patio installations.

• IP65 waterproof rating for protection against rain and splashes.
• Durable aluminum construction for improved thermal management.
• UL certification ensures adherence to electrical safety standards.

How flexible is installation and expansion?

EVERYGROW lights use a one-piece daisy-chain design allowing end-to-end connection so you can create longer runs without extra wiring. A single switch controls the system and many lights can be linked together, giving freedom to scale lighting to benches, aisles or rows.

• Connect up to 120 fixtures in approved configurations for large layouts.
• Recommended mounting height: 30–50 inches above plant canopy for even coverage.
• Protect unused sockets from moisture when not connected.

What performance metrics and efficiency should I expect?

The string delivers a high luminous flux and a strong photosynthetic photon output to improve light availability across plant tops. With a high power factor and efficient LED array, it provides substantial light without excessive energy waste.

• 288 LED chips across the string for even distribution.
• Approximately 15000 lumens and 100 lumen/watt efficiency.
• Photosynthetic photon flux around 23.5 μmol/s for effective plant light delivery.

Who this is for: growers looking for a weatherproof, scalable lighting solution for greenhouses, elevated beds or outdoor plant displays will benefit from EVERYGROW’s blend of full-spectrum output, expandability and certified safety. It fits hobbyist gardeners upgrading seedling setups, small commercial growers needing reliable supplemental light, and anyone who wants an easy-to-deploy string light that stands up to outdoor conditions.
