Espird Outdoor LED Grow Light 6-Bulb 21.3ft Full-Spectrum Strip with 24H Timer & Waterproof IP44

Espird Outdoor LED Grow Light with Timer is a 21.3-foot, UL‑certified, waterproof string of six full‑spectrum E26 LED bulbs designed to support seedlings, vegetative growth, flowering and fruiting with a built‑in mechanical 24‑hour timer.

These outdoor string grow lights combine a robust waterproof design and a mechanical 24‑hour timer with full‑spectrum LED bulbs plus 660nm red supplementation to support plant photosynthesis and development across growth stages. The set arrives as a 6‑bulb strip (connectable end‑to‑end) offering 15,000 lumens and an aluminum body that reflects light back toward plants. UL certification and IP44 protection make it well suited for greenhouse benches, patios, and seasonal outdoor setups where durability matters.

How does the timer make daily light scheduling easier?

The integrated mechanical 24‑hour timer lets you automate daily light cycles without relying on photocell sensors that can be triggered by stray artificial light. Set the dial to the desired on/off pattern for consistent photoperiods, helping maintain predictable plant responses.

• Mechanical 24‑hour dial avoids false triggers from ambient light.
• Simple manual pins for on/off segments—no app required.
• Reliable for repeated daily schedules in outdoor conditions.

What spectrum and output do these bulbs provide for plant growth?

Each bulb contains 48 LEDs blending warm (3000K), cool (5000K) and supplemental 660nm red diodes to deliver a broad 400–700nm usable spectrum and extra red light that supports flowering and fruiting stages. The whole 6‑bulb strip offers roughly 15,000 lumens and a photosynthetic photon flux appropriate for seedlings to mature plants when positioned at recommended heights.

• Combination of 3000K, 5000K and 660nm red chips in every bulb.
• Total 288 LED chips across the strip with 100 lm/W efficiency.
• Designed to cover seedling trays up to greenhouse benches with even spread.

How weatherproof and safe is this grow light for outdoor use?

Espird’s string includes waterproof lamp holders, end‑to‑end connectors and a rubber‑covered switch, rated IP44 to resist splashes and light rain. The product is UL certified, which reflects independent testing for electrical safety and reduces risks common in outdoor lighting setups.

• IP44 protection for splash resistance in outdoor settings.
• UL certification ensures standardized electrical safety testing.
• Rubber‑covered switch and sealed sockets—screw bulbs fully for best seal.

Can I scale the lighting layout for different spaces?

The string design supports cascading multiple strips: a single switch can control up to 120 lights when connected end‑to‑end, making it flexible for longer rows or larger benches. You can also use fewer bulbs by protecting unused sockets to maintain water resistance.

• Connect up to 20 six‑bulb strips (or equivalent) under one switch.
• Recommended mount height: 30–50 inches above plant canopy for balanced coverage.
• Keep unused screw sockets covered to preserve IP44 protection.

Who is this for: growers needing a durable, easy‑to‑set outdoor lighting solution for greenhouses, balconies, or garden workspaces. Espird’s UL‑certified, waterproof strip suits hobbyists and small commercial producers who want automated daily cycles, broad-spectrum light with red enhancement, and a scalable layout that grows with their space.
