A compact, 4W USB grow light designed for indoor plants that don’t get enough natural light. The 6000K full-spectrum bar combines 40 white LEDs (simulating noon daylight) with 8 red LEDs (620–660nm) to support every growth stage — from seedlings to established houseplants.
Your plants need light — this delivers it reliably
Most indoor spaces provide a fraction of the light plants actually need. North-facing rooms, windowless offices, and seasonal shifts in daylight can all slow growth, cause leaf drop, and lead to leggy, underperforming plants. This lamp is designed to fill that gap without taking over your space.
At 4W, it draws less power than most USB chargers while delivering a focused, full-spectrum output tuned for photosynthesis. The white LEDs replicate the quality of midday sunlight. The red LEDs target the 620–660nm wavelength range — the band plants rely on most heavily for flowering and fruiting.
What’s included
- LED light bar (7.8 in / 19.8 cm) — 40 white (6000K) + 8 red (620–660nm) LEDs
- Flexible gooseneck arm (12.2 in / 30.9 cm) — fully adjustable in all directions
- Soil stake / ground anchor (4.1 in / 10.4 cm) — inserts directly into the pot
- Inline controller — brightness and timer buttons built into the USB cable
- USB-A cable (76.7 in / 194 cm) — powers from any USB-A port, charger, laptop, or power bank
Setup in 3 steps
- Connect. Screw the LED light bar onto the gooseneck arm. Tighten until fully seated — no tools required.
- Insert the stake. Push the soil stake into the pot near your plant's base. The stake holds the entire lamp upright without any surface mount or clamp needed.
- Adjust height and angle. Bend the gooseneck so the light bar sits 6 to 12 inches above your plant's canopy. The arm holds its position once adjusted.
Using the inline controller
- Power on/off: Press the power button once to turn on at the last-used brightness. Press again to turn off.
- Brightness: Press the dimmer button to step through 5 levels — 20% → 40% → 60% → 80% → 100%.
- Timer: Press the timer button to set a daily cycle — 4H on / 20H off, 8H on / 16H off, or 12H on / 12H off. Once set, the lamp repeats automatically at the same time each day without needing to be replugged.
Why 6000K — and what the red LEDs add
Light temperature (measured in Kelvin) describes the colour quality of the output. At 6000K, this lamp produces a crisp daylight-white light that closely matches the colour of midday sun — the optimal range for photosynthesis across nearly all growth stages.
The 40 white LEDs provide broad-spectrum coverage: blue wavelengths that drive compact, vigorous vegetative growth, and green wavelengths that penetrate deeper into the plant canopy. The 8 red LEDs at 620–660nm specifically promote flowering, fruiting, and root development. Together, the two spectra replicate the full range of a clear summer day.
6000K full spectrum
Covers all growth stages. Mimics midday sunlight. Colour rendering index ~95% — soft enough to also serve as a reading or desk lamp.
620–660nm targeted
Promotes flowering, blooming, and fruiting. Activates phytochrome receptors that regulate plant development cycles and encourage root development.
Getting the best results
- Start with less, increase gradually. Begin at 40–60% brightness and monitor for 1–2 weeks before increasing intensity. Signs of too much light: bleaching, browning tips, or colour fading.
- Don't exceed 16 hours of light per day. Plants need a dark period for cellular rest. The lamp's presets — 4H, 8H, and 12H — are all within safe limits.
- Combine with natural light, don't replace it. Use this lamp to supplement gaps — morning shade, winter months, or a north-facing window.
- Keep the LED bar clean. Dust reduces light output over time. Wipe the LED bar with a dry cloth every 4–6 weeks to maintain full brightness.
- Adjust height as the plant grows. Check every 2–4 weeks and raise the light bar as your plant's canopy develops. The goal is consistent distance, not a fixed height.
- USB adapter tip. This lamp ships with a USB-A connector. If your nearest power source is USB-C only, a standard USB-A to USB-C adapter works perfectly. Any 5V USB source with at least 1A output is sufficient.
AgrilHoTech warranty coverage
LED lights — 6 months
If the LEDs fail to illuminate or significantly underperform under normal indoor use within 6 months of purchase, we will replace the unit. This covers manufacturing defects in the LED bar and light output only.
Physical damage
Breakage, gooseneck damage from excessive force, water contact damage, cable damage, and damage from improper use are not covered. Handle the gooseneck with care — it is adjustable but not designed for repeated extreme bending.
How to make a warranty claim
- Contact AgrilHoTech support at [your support email or contact page link].
- Include your order number and a short description of the issue.
- Attach a photo or short video showing the defect.
- We will respond within 2 business days and arrange a replacement if the claim is valid.
Will this lamp work for my low-light plant that barely gets any sun?
Yes — this is exactly the scenario this lamp is designed for. Plants like Pothos, Philodendron, Peace Lily, and ZZ Plant adapt well to supplemental LED light. Use the 8H or 12H timer at 60–80% brightness for best results.
How do I power it if I don't have a USB-A port nearby?
The lamp uses a standard USB-A connector with a 194cm cable. It works with any USB-A power source — a phone charger, laptop, USB hub, or power bank. If you only have USB-C ports, a USB-A to USB-C adapter (not included) works perfectly. The lamp requires 5V at 1A — well within any standard USB charger's output.
What is the difference between the 4H, 8H, and 12H timer settings?
All three work on a 24-hour repeating cycle from the time you first activate the timer. 4H on / 20H off suits succulents that prefer long dark periods. 8H on / 16H off is suitable for most established tropical plants. 12H on / 12H off is ideal for seedlings, herbs, and fast-growing plants. The timer may vary by up to 15 minutes per cycle — this is normal.
Can I use this for growing herbs in the kitchen?
Yes. Insert the stake into the herb pot, set the timer to 12H, and use 80–100% brightness. Basil, Mint, Parsley, and Coriander all respond positively. Keep the light bar 5–8 inches above the growing tips and raise it as the plant grows taller.
Will the lamp get hot enough to damage my plant?
No. At 4W, the LED bar runs cool — it may feel slightly warm to the touch after extended use, but not hot. LEDs do not emit significant infrared heat toward the plant. Keeping the bar 6 inches or more above the canopy eliminates any heat risk entirely.
Is this suitable for a large Monstera or Bird of Paradise?
Not as a primary light source for very large plants. The 4W output and 19.8cm bar are best suited for pots up to 6–8 inches in diameter. A large Monstera would benefit from the light directly under the bar, but full coverage would require two or more lamps positioned around the plant.
