Espird Outdoor LED Grow Light Strip — 41FT 12-Bulb Full-Spectrum Waterproof, UL-Certified for Greenhouse

Espird Outdoor LED Grow Light is a 41-foot, 12-bulb, full-spectrum, UL-certified waterproof string designed to support all plant stages from seedling to fruiting.

Bring reliable supplemental lighting to greenhouses, patios, and garden frames with a durable, weather-resistant string of E26 sockets and full-spectrum bulbs. Engineered for outdoor use and tested to UL standards, this system blends red, warm white, and daylight LEDs to cover photosynthesis and photomorphogenesis bands while offering flexible installation and long runtime efficiency.

How does this grow light support different plant stages?

The Espird strip combines 3000K warm white, 5000K daylight, and targeted 660nm red LEDs in each bulb to address both growth and flowering needs. The mix of wavelengths spans 400–700nm for photosynthesis and extends modeling light up to 780nm for developmental cues, so one setup can serve seedlings through harvest.

• Full-spectrum bulbs include 24 warm, 18 daylight, and 6 red LED chips each
• 400–700nm coverage fuels photosynthesis across stages
• 660nm red LEDs enhance flowering and fruiting development

Is this light safe and reliable for outdoor use?

Yes — the Espird system is UL certified, indicating it met independent safety testing for electrical and construction standards. The string features IP44-rated waterproofing on sockets, connectors, and a rubber-coated switch, making it suitable for covered outdoor spaces and greenhouses.

• UL certification for electrical safety and quality assurance
• Waterproof E26 sockets and end-to-end connectors (IP44)
• Covered on/off switch and protective design for outdoor settings

How energy-efficient and powerful is the lighting?

The system delivers 30,000 lumens across 576 LED chips at roughly 100 lm/W and a photosynthetic photon flux of 23.5 µmol/s, balancing visible output with useful plant photons. An aluminum lamp body helps reflect light back toward plants, reducing wasted illumination and improving uniformity.

• 576 LED chips total for broad, even lighting
• Approx. 30,000 lumens and 100 lumens per watt efficiency
• Aluminum housing reflects photons to optimize plant exposure

Can I customize the layout for different garden sizes?

Yes — lights connect end-to-end so you can expand or shorten runs to fit benches, trellises, or greenhouse bays. One switch can power up to 120 lamps (configurations vary by bulb count), and the recommended hanging height is 30–50 inches above the canopy for general crops.

• End-to-end connectivity for flexible layout and scaling
• Supports up to 120 lights from a single switch in specified groupings
• Recommended mounting height: 30–50 inches above plants

Who this is for: Gardeners and small-scale growers who need a dependable, weather-resistant full-spectrum lighting solution for outdoor or greenhouse use. Espird’s string is well suited to hobbyists and market gardeners growing vegetables, herbs, and fruiting plants like tomatoes, basil, lettuce, raspberries, and root crops that benefit from balanced spectral coverage and robust outdoor construction. The product also appeals to anyone prioritizing safety certifications and expandable configurations for varied growing spaces.
